Description

wo 2013/032693 ED BACTERIAL STRAIN OF THE GENUS BURKHOLDER/A AND PESTICIDAL METABOLITES THEREFROM-FORMULATIONS AND USES TECHNICAL FIELD Provided herein is a species of lderia sp with no known pathogenicity to vertebrates, such as mammals, fish and birds but pesticidal ty against plants, algae, insects, fungi, arachnids, such as mites and nematodes and formulations and compositions comprising said species. Also provided are natural products, formulations and compositions derived from a culture of said species and methods of controlling algae and arachnids, such as mites, using said lderia and/or said natural products.

BACKGROUND l products are substances produced by es, plants, and other organisms.

Microbial natural products offer an abundant source of chemical diversity, and there is a long history of utilizing natural products for pharmaceutical purposes. One such compound is FR901228 isolated from Chromobacterium and has been found to be useful as an antibacterial agent and antitumor agent (see, for example, Ueda et al., US Patent No.7,396,665).

However, ary metabolites produced by microbes have also been successfully found to have uses for weed and pest control in agricultural applications (see, for example, Nakajima et al. 1991; Duke et al., 2000; Lydon & Duke, 1999; Gerwick et al., US Patent No. 7,393,812). Microbial natural products have been also successfully developed into agricultural icides (see, for example, Salama et al. 1981; Thompson et al., 2000; Krieg et al. 1983).

Sometimes, such natural products have been combined with chemical pesticides (see, for example, Gottlieb, US Patent No. 4,808,207).

Acaricides Acaricides are compounds that kill mites (miticides) and ticks (ixodicides). This class of pesticides is large and includes antibiotics, carbamates, idine acaricides, roids, mite growth regulators, and organophosphate acaricides. Besides chemical ides, diatomaceous earth and fatty acids can be used to control mites. They typically work through disruption ofthe e, which dries out the mite. In addition, some essential oils such as mint oil, are used to control mites. In spite ofthe great variety ofknown acaricide compounds, mites remain a serious problem in agriculture because ofthe damage they cause to wo 2013/032693 the crops. They can produce several tions during one season, which facilitates rapid development of resistance to the acaricide ts used. Hence, new pesticide products with new target sites and novel modes of action are critically .

Algicides Algae come in many forms. These include: (1) microscopic, lled algae, filamentous algae that resemble hair, algae that grow in sheets and macroalgae that look like plants; (2) algae that live inside the outer integument ("skin") or calcium shell of some corals, anemones, and other e invertebrates called zooxanthellae; (3) very hard-to-remove little dots of green that sometimes grow on aquarium panels which also are not algae, but diatom or radiolarian colonies (microscopic, lled, animals with hard shells) with algae incorporated in their matrix.

Growth of algae in a small amount of water retained in the container over a significant period of time can be considerable, which is highly rable. As a result, algae can cause clogging of filters in water filtration devices, undesirable smells and appearance in pools, exhaustion of dissolved oxygen, and suffocation of fishes and shellfishes to death. In addition to being t in water, algae may also be present in industrial materials which are exposed to the weather and light, such as coatings containing organic film formers on mineral substrates, e es, wood paints and also materials made of cs.

Algae control can be divided into four categories: biological, ical, physical and chemical controls. A few pertinent facts hold for all methods of algae control. For example, Turbo and Astrea snails, some blennies, some tangs, among others are good grazers. Snails are the most widely used scavengers, and generally the best choice. Some parts of the country seem to favor the use of sea urchins, dwarf angels. The former die too easily and move the decor about, and the latter can be problematical with eating expensive invertebrates. Other methods include functional protein skimmers, with or without ozone and ultraviolet sterilizers. These physical filters remove and destroy algae on exposure and help oxidize nutrients as the water is circulated. Antibiotics may also be used. However, they treat the symptoms only without dealing with the cause(s) of the algae problem. The factors can contribute to water system being out of balance. Copper, usually in the form of copper sulfate solution has been employed as an algicide~ as well as a general epizootic parasite preventative. This metal is useful in treatment and quarantine tanks, dips and fish-only ements but it is persistent and toxic to all life, especially non-fish. wo 2013/032693 Burkholderia The Burkholderia genus, 13-subdivision of the proteobacteria, comprises more than 40 species that inhabit diverse ecological niches nt et al., 2008). The bacterial species in the genus Burkholderia are tous organisms in soil and rhizosphere (Coenye and Vandamme, 2003; Parke and -Sherman, 2001). Traditionally, they have been known as plant pathogens, B. cepacia being the first one discovered and identified as the pathogen causing disease in onions (Burkholder, 1950). Several Burkholderia species have developed beneficial interactions with their plant hosts (see, for example, Cabballero-Mellado et al., 2004, Chen et al., 2007). Some Burkholderia species have also been found to be opportunistic human pathogens (see, for example, Cheng and Currie, 2005 and Nierman et al., 2004). onally, some Burkholderia species have been found to have ial as biocontrol products (see for example, Burkhead et al., 1994; Knudsen et al., 1987; Jansiewicz et al., 1988; Gouge et al., US Patent Application No. 2003/0082147; Parke et al., US Patent No. 6,077 ,505; Casida et al., US Patent No. 6,689,357; Jeddeloh et al., W02001055398; Zhang et al., US Patent No.7,141 ,407).

Some species of in this genus have been effective in bioremediation to aminate polluted soil or groundwater (see, for example, Leahy et al. 1996). Further, some Burkholderia species have been found to e a variety of extracellular enzymes with proteolytic, lipolytic and hemolytic activities, as well as toxins, antibiotics, and siderophores (see, for example, Ludovic et al., 2007; Nagamatsu, 2001).

PCT/US2011!026016 discloses a Burkholderia species, particularly Burkholderia A396 and compounds derived from said species with no known pathogenicity to vertebrates with activity against plants, insects, fungi and nematodes.

Oxazoles, Thiazoles and s Oxazoles, thiazoles and indoles are widely distributed in plants, algae, sponges, and microorganisms. A large number of natural products n one or more ofthe five-membered oxazole, thiazole and indole s/moieties. These l products exhibit a broad spectrum ofbiological activity of demonstrable therapeutic value. For example, bleomycin A (Tomohisa et al.), a widely prescribed anticancer drug, effects the oxidative degradation of DNA and uses a bithiazole moiety to bind its target DNA ces (Vanderwall et al., 1997). acin (Ming et al., 2002), a thiazoline-containing peptide antibiotic, interdicts bacterial cell wall new thesis by complexation with C55-bactoprenolpyrophosphate. Thiangazole (Kunze et al., 1993) contains a tandem array of one oxazole and three thiazolines and exhibits ral activity (Jansen et al., 1992). Yet other oxazole/thiazole-containing natural products such as thiostrepton (Anderson et al., 1970) and A (Selva et al., 1997) inhibit translation steps in bacterial protein synthesis. More than 1000 alkaloids with the indole skeleton have been reported from microorganisms. One-third of these compounds are peptides with masses beyond 500 Da where the indole is tryptophan derived. The structural variety of the remaining two thirds is higher, and their biological activity seems to cover a broader range, including antimicrobial, ral, cytotoxic, icidal, antithrombotic, or enzyme inhibitory activity.

EXAMPLES The compositions and methods set forth above will be further illustrated in the following, non-limiting Examples. The examples are illustrative of s embodiments only and do not limit the d invention regarding the materials, conditions, weight ratios, process parameters and the like recited herein. 1. Example 1. Isolation and identification of the microbe 1.1 Isolation ofthe microorganism The microbe is ed using established techniques know to the art from a soil sample collected under an evergreen tree at the Rinnoji Temple, Nikko, Japan. The isolation is done using potato dextrose agar (PDA) using a procedure described in detail by Lorch et al. , 1995.

In this procedure, the soil sample is first diluted in sterile water, after which it is plated in a solid agar medium such as potato dextrose agar (PDA). The plates are grown at 25°C for five days, after which individual microbial colonies are isolated into separate PDA plates. The isolated bacterium is gram negative, and it forms round, opaque cream-colored colonies that change to pink and pinkish-brown in color and mucoid or slimy over time. wo 2013/032693 2012/050807 1.2. Identification on the rganism The microbe is identified based on gene sequencing using universal bacterial primers to amplify the 16S rRNA region. The following ol is used: Burkholderia sp. A396 is cultured on potato-dextrose agar plates. Growth from a 24 hour-old plate is scraped with a sterile loop and re-suspended in DNA extraction . DNA is extracted using the MoBio Ultra Clean Microbial DNA extraction kit. DNA extract is checked for quality/quantity by running S]tl on a 1% agarose gel.

PCR reactions are set up as follows: 2 Jtl DNA extract, 5 Jtl PCR buffer, 1 Jtl dNTPs (10 mM each), 1.25 Jtl forward primer (27F; (SEQ ID N0:1), 1.25 Jtl reverse primer (907R; (SEQ ID N0:2)) and 0.25 Jtl Taq enzyme. The reaction volume is made up to 50 Jtl using sterile nuclease-free water. The PCR reaction includes an initial denaturation step at 95°C for 10 minutes, followed by 30 cycles of 94°C/30 sec, 57°C/20 sec, 0 sec, and a final extension step at 72°C for 10 minutes.

The product's approximate concentration and size is calculated by running a 5 Jtl volume on a 1% agarose gel and comparing the product band to a mass ladder.

Excess primers, dNTPs and enzyme are removed from the PCR product with the MoBio PCR clean up kit. The d PCR product as directly sequenced using s 27F (same as above), 530F (SEQ ID , 1114F (SEQ ID N0:4)) and 1525R (SEQ ID N0:5)), 1100R (SEQ ID N0:6)), 519R (SEQ ID N0:7).

The 16S rRNA gene sequence of strain A396 is compared with the ble 16S rRNA gene sequences of representatives of the ~-proteobacteria using BLAST. Strain A395 A396 is closely related to members of the Burkholderia cepacia complex, with 99% or higher similarity to several isolates of Burkholderia multivorans, Burkholderia vietnamensis, and Burkholderia cepacia. A BLAST search excluding the B. cepacia complex, showed 98% similarity to B. rii, B. gladioli and lderia sp. isolates.

A distance tree of results using the neighbor joining method, showed that A396 is related to Burkholderia multivorans and other Burkholderia cepacia complex isolates.

Burkholderia plantarii and Burkholderia glumae grouped in a separate branch of the tree.

The isolated Burkholderia strain was found to n the following sequences: Forward sequence, DNA sequence with 27F primer, 815 nucleotides (SEQ ID N0:8); Reverse sequence, 1453 bp, using primers 1525R, 1100R, 519R (SEQ ID N0:9); Reverse sequence 824 bp using primer 907R (SEQ ID NO: 10); Forward sequence 1152 bp using primer 530F (SEQ ID NO: 11); Forward sequence 1067 bp using 1114F primer (SEQ ID NO: 12); Reverse sequence wo 2013/032693 1223 bp using 1525R primer (SEQ NO: 13); Reverse sequence 1216 bp using 1100R primer (SEQ ID ; Reverse sequence 1194 bp using 519R primer (SEQ ID N0:15) 1.3. Proofthat Burkholderia A396 does not belong to Burkholderia cepacia complex 1.3 .1 Molecular Biology work using specific PCR primers In order to confirm the identification of Burkholderia A396 as Burkholderia multivorans, additional sequencing of housekeeping genes is performed. Burkholderia orans is a known member of the Burkholderia cepacia complex. Efforts are focused on PCR of recA genes, as described by Mahenthiralingam et al., 2000. The following primers are used: (a) BCR1 and BCR2 set forth in Mahenthiralingam et al., 2000 to confirm B. cepacia complex match and (b) BCRBM1 and BCRBM2 set forth Mahenthiralingam et al, 2000 to confirm B. multivorans match. A product-yielding PCR reaction for the first primer set would confirm that the microbe belongs to the B. cepacia complex. A product-yielding PCR reaction for the second primer set would m that the microbe is indeed B. multivorans.

No PCR product is obtained for either pair of primers. The performance of the PCR reaction and primers is tested using Burkholderia multivorans ATCC 17616 (positive control) and Pseudomonas scens (negative control). Strong bands are observed both forB. multivorans using both sets of primers. No bands are observed for Pseudomonas fluorescens.

The results indicate that A396 is a Burkholderia, but not a member of the B. a complex, and not Burkholderia multivorans. This is also demonstrated in a comparative culture experiment in which both A396 and a type culture of B. multivorans are grown y-side in a shake culture, and the growth is monitored daily using optical density measurements at 600 nm.

Under the set conditions, species A396 grew much faster than the B. multivorans type strain (Figure 1). 1.3.2 DNA-DNA Hybridization In order to confirm that isolate A396 is a new species of Burkholderia, a DNA-DNA ization ment with Burkholderia multivorans (the t 16SrRNA sequence match) is conducted. Biomass for both A396 and B. multivorans is produced in ISP2 broth, grown over 48 hours at 200 °C in Fernbach flasks. The s is cally harvested by fugation. The broth is decanted and the cell pellet is resuspended in a 1: 1 solution of water: isopropanol. DNA-DNA hybridization experiments are performed by the DSMZ, the German Collection of Microorganisms and Cell Cultures in Germany. DNA is isolated using a French pressure cell (Thermo Spectronic) and is purified by chromatography on hydroxyapatite as described by Cashion et al., 1977. DNA-DNA hybridization is carried out as described by wo 2013/032693 De Ley et al., 1970 under eration of the modifications described by Huss et al., 1983 using a model Cary 100 Bio UV/VIS-spectrophotometer ed with a Peltier thermostatted 6x6 multicell changer and a temperature controller with in-situ ature probe (Varian).

DSMZ reported% DNA-DNA similarly between A396 and Burkholderia multivorans of 37.4%. The results indicate that Burkholderia sp strain A396 does not belong to the s lderia multivorans when the recommendations of a threshold value of 70% DNA-DNA similarity for the tion of bacterial species by the ad hoc committee (Wayne et al., 1987) are considered. 1.4. Biochemicalprofile using Biolog GN2 plates For the carbon source utilization profile, A396 is grown overnight on Potato Dextrose Agar (PDA). The culture is transferred to BUG agar to produce an te culture for Biolog experiments as recommended by the manufacturer (Biolog, Hayward, CA).

The biochemical profile of the microorganism is determined by inoculating onto a Biolog GN2 plate and reading the plate after a 24-hour incubation using the MicroLog 4- automated microstation system. Identification of the unknown bacteria is attempted by comparing its carbon utilization pattern with the Microlog 4 Gram negative database.

No clear definitive matches are found to the Biolog profile. The closest matches all had less than 35% rity with A396: Pseudomonas spinosa (Burkholderia), Burkholderia cepacia, and Burkholderia pseudomallei.

Fatty acid composition After incubation for 24 hours at 28°C, a loopful ofwell-grown cells are harvested and fatty acid methyl esters are ed, separated and identified using the Sherlock Microbial Identification System (MIDI) as described (see Vandamme et al., 1992). The predominant fatty acids present in the Burkholderia A396 are as follows: 16:0 (24.4%), cyclo 17:0 (7.1 %), 16:0 3- 0H (4.4%), 14:0 (3.6%), 19:0 w8c (2.6%) cyclo, 18:0 (1.0%). Summed feature 8 ising 18:1 m7c) and summed feature 3 ising of 16:1 m7c and 16:1 m6c) corresponded to 26.2% and 20.2% ofthe total peak area, respectively. Summed feature 2 comprising 12:0 ALDE, 16:1 iso I, and 14:0 3-0H) corresponded to 5.8% ofthe total peak area while summed feature 5 comprising 18:0 ANTE and 18:2 ru6,9c corresponded to 0.4%. Other fatty acids detected in A396 in minor ties included: 13:1 at 12-13 (0.2%), 14:1 ru5c (0.2%), 15:0 3-0H (0.13%), 17:1 m7c (0.14%), 17:0 (0.15%), 16:0 iso 3-0H (0.2%), 16:0 2-0H (0.8%), 18:1 m7c 11-methyl (0.15%), and 18:1 2-0H (0.4%).

A comparison ofthe fatty acid composition ofA396 with those ofknown microbial strains in the MIDI database suggested that the fatty acids in the novel strain A396 were most similar with those ofBurkholderia cenocepacia. 1.6 Resistance to Antibiotics Antibiotic susceptibility ofBurkholderia A396 is tested using antibiotic disks on Muller- Hinton medium as bed in PML Microbiological's technical data sheet #535. Results obtained after 72-hour incubation at 25°C are presented in Table 2 below. wo 2013/032693 Table 2: Susceptibility of MBI-206 to various antibiotics.+++ very susceptible,++ susceptible, - resistant Concentration (tJ.g) Susceptible Tetracycline 30 cin 30 +++ Erythromycin 15 Streptomycin 10 llin 10 Ampicillin 10 Oxytetracycline 30 Chloramphenicol 30 ++ Ciprofloxacin 5 ++ Gentamicin 10 Piperacillin 100 +++ Cefuroxime 30 Imipenem 10 +++ Sulphamethoxazole- Trimethoprim 25 ++ The results indicate that the antibiotic susceptibility spectrum ofBurkholderia A396 is quite different from pathogenic B. cepacia complex strains. Burkholderia A396 is susceptible to kanamycin, chloramphenicol, ciprofloxacin, cillin, imipenem, and a combination of sulphamethoxazole and trimethoprim. As a comparison, Zhou et al., 2007 tested the susceptibility of 2,621 different strains in B. cepacia complex isolated from cystic fibrosis patients, and found that only 7% and 5% of all strains were susceptible to imipenem or ciprofloxacin, respectively. They also found 85% of all s to be resistant to chloramphenicol (15% tible), and 95% to be ant (5% susceptible) to the ation of sulphamethoxazole and trimethoprim. Results of Zhou et al., 2007 are similar to those of Pitt et al., 1996 who determined antibiotic resistance among 366 B. cepacia isolates and reported that most ofthem are resistant to ciprofloxacin, cefuroxime, imipenem, chloramphenicol, tetracycline, and sulphametoxacole. wo 2013/032693 2. e 2: Burkholderia formulation and isolation of Fractions from Formulated Product The following procedure is used for the purification of compounds extracted from a ated product of MBI-206 containing a whole cell broth of a culture of Burkholderia sp.: The culture broth derived from the 10-L fermentation Burkholderia (A396) in Hy soy growth medium and formulated using methyl 0.1 %and propylparaben, 0.1 % l 0.67% and Glycosperse .67% is extracted with Amberlite XAD-7 resin (Asolkar et al., "Weakly cytotoxic polyketides from a marine-derived mycete of the genus Streptomyces strain CNQ-085." J. Nat. Prod. 69:1756-1759. 2006) by shaking the cell sion with resin at 225 rpm for two hours at room temperature. The resin and cell mass are collected by filtration through cheesecloth and washed with DI water to remove salts. The resin, cell mass, and cheesecloth are then soaked for 2 h in acetone after which the acetone is ed and dried under vacuum using rotary evaporator to give the crude extract (MBIFP-CE). The crude extract is then fractionated by using reversed-phase C18 vacuum liquid chromatography (H20/CH30H; gradient 80:20 to 0:100%) to give 10 fractions (see Figure 1 for schematic). These fractions are then trated to dryness using rotary ator and the resulting dry residues are ed for biological activity using a whole plant herbicidal assay. The active fractions, fractions 3, 4, 5 and 6 and indicated as MBIFP-3, MBIFP-4, MBIFP-5, and MBIFP-6 tively are then subjected to repeatedly to ed phase HPLC separation (Spectra System P4000 (Thermo ific) to give pure compounds, which are then screened in abovementioned bioassays to locate/identify the active compounds (see Figure 2). 2.1 Analysis ofFormulation fractions These fractions are analyzed on a Thermo high performance liquid chromatography (HPLC) instrument equipped with Finnigan Surveyor PDA plus detector, autosampler plus, MS pump and a 4.6 mm x 100 mm Luna C18 5 f..Lm column (Phenomenex). The solvent system consisted of water (solvent A) and acetonitrile (solvent B). The mobile phase begins at 10% solvent B and is linearly increased to 100% solvent B over 20 min and then kept for 4 min, and finally returned to 10% solvent B over 3 min and kept for 3 min. The flow rate is 0.5 mL/min.

The injection volume is 10 JLL and the samples are kept at room temperature in an auto sampler.

To discover the identity of the compound, additional spectroscopic data such as LC/MS and UV are recorded. Compound corresponding to fraction 5, with a retention time of 17.45 s is not found in any of the starting materials, which indicates that the compound is a product of a chemical reaction between natural products in the ial fermentation broth and one or more of the compounds found in the formulation agents.

The different carbon chain alcohols were used in the formulation and the formation ofthe new parabens were monitored using LCMS.

Four separate formulation experiments were performed using butanol, hexanol, octanol and cetyl alcohol and all other ients were kept same. The formulation products were extracted over the period of 2 days and 3 weeks. The crude extract obtained from these formulations were analysed by LCMS. The corresponding parabens formed for all alcohols except for cetyl l. The yield ofthe parabens was found to be the highest for butyl n, followed by hexyl paraben and then octyl n for the one day old formulation product. The is result even after 3 weeks remain the same order ie, butyl paraben > hexyl paraben > octyl paraben. Thus, the rate of ion ofthese parabens such as butyl paraben, hexyl paraben & octyl paraben was found to depend on the carbon chain (number of carbon) of the t (alcohol) ofthe corresponding alcohol used in the formulation (butanol (C4) > hexanol (C6) > octanol (C8) etc). The formation of cetyl paraben was not detected till 3 weeks.

The yields ofthese parabens were found to increase over the time.

Another set of experiments were carried out to understand the role ofwhole cell broth (WCB) in the ion ofthe new paraben analogues. In 4 different expt. with were carried out with following changes in the formulation- Expt-1 : Propy1paraben (No methy1paraben) + WCB + other ingredients Expt-2: Methylparaben (No Propylparaben)+ WCB +other ingredients Expt-3: No parabens (both)+ WCB +other ients.

Expt-4: MethylParaben+ Propylparaben+ other ingredients+ No WCB.

The above formulations were extracted separately and the crude extract obtained were then analysed using LCMS. The formation ofthe hexyl paraben was observed only in the first two experiments. Thus, these experiments suggested that WCB plays a very important role in the formation ofthese parabens. 3. Example 3. Isolation of Templazole A and B s and Materials The following procedure is used for the purification of Templazole A and B extracted from cell culture ofBurkholderia sp (see Figure 3): The culture broth derived from the 10-L fermentation Burkholderia (A396) in Hy soy growth medium is extracted with Amberlite XAD-7 resin (Asolkar et al., 2006) by shaking the cell suspension with resin at 225 rpm for two hours at room temperature. The resin and cell wo 2013/032693 mass are ted by filtration through cheesecloth and washed with DI water to remove salts.

The resin, cell mass, and cheesecloth are then soaked for 2 h in acetone after which the acetone is filtered and dried under vacuum using rotary evaporator to give the crude extract. The crude t is then fractionated by using reversed-phase Cl8 vacuum liquid chromatography (H20/CH30H; gradient 90:10 to 0:100%) to give 11 fractions. These fractions are then concentrated to dryness using rotary evaporator and the resulting dry residues are screened for biological activity using 96 well plate lettuce seeding assay. The active fractions are then subjected to reversed phase HPLC (Spectra System P4000 (Thermo Scientific) to give pure compounds, which are then screened in above mentioned bioassays to /identify the active compounds.

The other active fraction 7 is also purified using HPLC C-18 column (Phenomenex, Luna lOu Cl8(2) 100 A, 250 x 30), water:acetonitrile gradient solvent system (0- min; 80% aqueous CH3CN, 10-25 min; 80- 60% aqueous CH3CN, 25-50 min; 60- 40% aqueous CH3CN, 50-60 min; 40% CH3CN, 60-80 min; 40-0% aqueous CH3CN, 80-85 min; 0- % s CH3CN) at 8 mL/min flow rate and UV detection of 210 nm, to give zole A, retention time 70.82 min.

Mass spectroscopy analysis of pure compounds is performed on a Thermo an LCQ Deca XP Plus ospray (ESI) instrument using both positive and negative ionization modes in a full scan mode (m/z 100-1500 Da) on a LCQ DECA XPplus Mass Spectrometer (Thermo Electron Corp., San Jose, CA). Thermo high mance liquid chromatography (HPLC) instrument equipped with Finnigan Surveyor PDA plus detector, autosampler plus, MS pump and a 4.6 mm x 100 mm Luna Cl8 5 11m column (Phenomenex). The solvent system consists of water (solvent A) and acetonitrile (solvent B). The mobile phase begins at 10% solvent B and is linearly increased to 100% solvent B over 20 min and then kept for 4 min, and finally ed to 10% solvent B over 3 min and kept for 3 min. The flow rate is 0.5 mL/min.

The injection volume was 10 11L and the samples are kept at room temperature in an auto r. The compounds are analyzed by LC-MS utilizing the LC and reversed phase chromatography. Mass spectroscopy analysis of the present compounds is performed under the following conditions: The flow rate of the nitrogen gas was fixed at 30 and 15 arb for the sheath wo 2013/032693 2012/050807 and aux/sweep gas flow rate, respectively. ospray ionization was performed with a spray voltage set at 5000 V and a capillary voltage at 35.0 V. The capillary temperature was set at 400°C. The data was analyzed on Xcalibur software. The active compound templazole A has a molecular mass of 298 and showed mlz ion at 297.34 in negative ionization mode. The LC-MS chromatogram for templazole B suggests a molecular mass of 258 and exhibited mlz ion at 257.74 in negative tion mode. 1H, 13C and 2D NMR spectra were measured on a Bruker 500 MHz & 600 MHz gradient field spectrometer. The reference is set on the internal standard tetramethylsilane (TMS, 0.00 ppm).

For structure elucidation oftemplazole A, the purified nd with a molecular weight 298 is further analyzed using a 500 MHz NMR instrument, and has 1H NMR b values at 8.44, 8.74, 8.19, 7.47, 7.31, 3.98, 2.82, 2.33, 1.08 and has 13C NMR values of b 163.7, 161.2, 154.8, 136.1, 129.4, 125.4, 123.5, 123.3, 121.8, 121.5, 111.8, 104.7, 52.2, 37.3, 28.1, 22.7, 22.7.

Templazole A has UV absorption bands at 226, 275, 327 nm, which suggested the presence of indole and oxazole rings. The molecular formula, C17H18N20 3, was determined by interpretation of 1H, 13C NMR and HRESI MS data mlz 96 (M+Ht (Calcd for C17H19N20 3, 299.1397), which entails a high degree ofunsaturation shown by 10 double bond equivalents. The 13C NMR spectrum revealed signals for all 17 carbons, including two methyls, a methoxy, a methylene carbon, an aliphatic methine, an ester carbonyl, and eleven aromatic carbons. The presence of 3'-substituted indole was ed from 1H -1H COSY and HMBC spectral data. The 1H -1H COSY and HMBC also indicated the presence of a ylic acid methyl ester group and a -CH2-CH-(CH3) 2 side chain. From the detailed analysis of 1H-1H COSY, 13C, and HMBC data it was derived that the compound contained an oxazole nucleus.

From the 2D analysis it was found that the iso-butyl side chain was attached at C-2 position, a carboxylic acid methyl ester at C-4 position and the indole unit at C-5 position to give templazole A.

The second herbicidally active compound, templazole B, with a lar weight 258 is further analyzed using a 500 MHz NMR instrument, and has 1H NMR b values at 7.08, 7.06, 6.75, 3.75, 2.56, 2.15, 0.93, 0.93 and 13C NMR values of b 158.2, 156.3, 155.5, 132.6, 129.5, 129.5, 127.3, 121.8, 115.2, 115.2, 41.2, 35.3, 26.7, 21.5, 21.5. The lar formula, is assigned as C15H18N20 2, which is ined by interpretation of 1H, 13C NMR and mass data.

The 13C NMR um revealed signals for all 15 carbons, including two methyls, two methylene carbons, one aliphatic e, one amide carbonyl, and nine aromatic carbons. The general nature of the structure was deduced from 1H and 13C NMR spectra that showed a para- substituted aromatic ring [b 7.08 (2H, d, J = 8.8 Hz), 6.75 (2H, d, J = 8.8 Hz), and 132.7, 129.5, wo 2013/032693 115.2, 127.3, 115.2, 129.5]. The 1H NMR spectrum of this structure together with the 1H- 1H COSY and HSQC spectra, displayed characteristic signals for an isobutyl moiety [b 0.93 (6H, d, J = 6.9 Hz), 2.15 (IH, sept., J = 6.9 Hz), 2.57 (2H, d, J = 6.9 Hz). In addition, an olefinic/aromatic proton at (b 7.06, s), and a carbonyl carbon group (b 158.9) were also found in the 1H and 13C NMR spectra. On inspection of the HMBC um, the H-1' signal in the isobutyl moiety correlated with the olefinic carbon (C-2, b 156.3), and the olefinic proton H-4 correlated with (C-5, b 155.5; C-2, 156.3 & C-1", 41.2). The methylene signal at b 3.75 correlated with C-5, C-4 as well as the C-2" of the para-substituted aromatic moiety. All these observed correlations suggested the tivity among the isobutyl, and the para-substituted benzyl es for the skeleton ofthe structure as shown. In addition, the carboxamide group is assigned at the para position of the benzyl moiety based on the HMBC correlation from the ic proton at H-4"& H-6" position. Thus, based on the above data, the structure was designated as templazole B. 4.

Isolation of Templamide A, B, 65 and FR901228 Methods and Materials The culture broth d from the 10-L fermentation Burkholderia (A396) in Hy soy growth medium is extracted with Amberlite XAD-7 resin (Asolkar et al., 2006) by shaking the cell suspension with resin at 225 rpm for two hours at room temperature. The resin and cell mass are collected by filtration through cheesecloth and washed with DI water to remove salts.

The resin, cell mass, and cheesecloth are then soaked for 2 h in acetone after which the acetone is filtered and dried under vacuum using rotary evaporator to give the crude extract. The crude extract is then fractionated by using reversed-phase C18 vacuum liquid chromatography (H20/CH30H; gradient 90: 10 to 0:100%) to give 11 fractions. These fractions are then concentrated to dryness using rotary evaporator and the ing dry residues are screened for biological activity using 96 well plate lettuce seeding (herbicidal) and early 3rd instar Beet Armyworm (insecticidal) assay. The active fractions are then subjected to repeatedly to reversed phase HPLC separation (Spectra System P4000 (Thermo Scientific) to give pure wo 2013/032693 compounds, which are then screened in above-mentioned bioassays to locate/identify the active compounds. To confirm the identity of the compound, additional spectroscopic data such as LC/MS, HRMS and NMR are recorded.

The active fraction 6 is purified further by using HPLC C-18 column (Phenomenex, Luna lOu Cl8(2) 100 A, 250 x 30), water:acetonitrile gradient solvent system (0-10 min; 80% aqueous CH3CN, 10-25 min; 80- 65% s CH3CN, 25-50 min; 65- 50% aqueous CH3CN, 50-60 min; 50-70% aqueous CH3CN, 60-80 min; 70- 0% aqueous CH3CN, 80-85 min; 0 - 20 % aqueous CH3CN) at 8 mL/min flow rate and UV detection of 210 nm, to give templamide A, retention time 55.64 min and FR901465, retention time 63.59 min and FR90128, ion time 66.65 min respectively.

The LC-MS analysis in positive mode ionization for mide B suggests a molecular mass of 537 based mlz ions at 538.47 [M + Ht and 560.65 [M +Nat. The wo 2013/032693 2012/050807 molecular weight for the compounds FR901465 and FR901228 are assigned as 523 and 540 tively on the basis of LCMS analysis. 1H, 13C and 2D NMR a are measured on a Bruker 600 MHz gradient field spectrometer. The reference is set on the internal standard tetramethylsilane (TMS, 0.00 ppm).

For structure elucidation oftemplamide A, the purified compound with molecular weight 555 is further analyzed using a 600 MHz NMR instrument, and has 1H NMR b values at 6.40, 6.39, 6.00, 5.97, 5.67, 5.54, 4.33, 3.77, 3.73, 3.70, 3.59, 3.47, 3.41, 2.44, 2.35, 2.26, 1.97, 1.81, 1.76, 1.42, 1.37, 1.16, 1.12, 1.04 and has 13C NMR values of b 173.92, 166.06, 145.06, 138.76, 135.71, 129.99, 126.20, , 99.75, 82.20, 78.22, 76.69, 71.23, 70.79, 70.48, 69.84, 60.98, 48.84, 36.89, 33.09, 30.63, 28.55, 25.88, 20.37, 18.11, 14.90, 12.81, 9.41.

The(+) ESIMS analysis for the second herbicidal compound, shows mlz ions at 538.47 [M + Ht and 560.65 [M +Nat corresponding to the molecular weight of 537. The molecular formula of N09 is determined by interpretation of the ESIMS and NMR data analysis.

The 1H and 13C NMR of this compound is similar to that of templamide A except that a new isolated -CH2- appear instead of the non-coupled ene group in templamide A. The small germinal coupling constant of 4.3 Hz is characteristic of the presence of an epoxide methylene group. The presence of this epoxide is further confirmed from the 13C NMR shift from 60.98 in templamide A to 41.07 in compound with MW 537. The molecular formulae difference between these two compounds is reasonably explained by elimination of the water molecule wo 2013/032693 2012/050807 followed by formation of epoxide. Thus, on the basis ofbased NMR and MS analysis the ure for the new compound was assigned and was designated as templamide B.

Example 14: Efficacy of Burkholderia sp. formulation (MBI 206) for control of two spotted spidermite (TSM) in strawberry — field data.

The efficacies of five traditional chemistry-derived and MBI 206 were evaluated for TSM control under field conditions. berry al’ transplants were set in the field in plastic mulched beds, 13 inches high and 27 inches across the top, and with 4 ft bed spacing.

Overhead irrigation was applied for 10 days after setting to aid in establishment of the transplants. Trickle irrigation was used for the remainder of the experiment. Each 12.5-ft. plot consisted of 20 plants in two ten-plant rows per bed. Plots were infested from a tory colony in four sessions with 10 to 20 motile TSM, per plant. Each session accomplished the infestation of one block of the experiment. The experiment consisted of treatments of various rates and schedules of application of miticides, some combined with an adjuvant, and a non- treated check. Treatments were replicated four times in a RCB design. Savey and Acramite treatments were applied before TSM densities reached threshold levels (6 Jan); the remainder of the treatment programs began 2 wks later. Treatments were applied using a hand-held sprayer with a spray wand outfitted with a nozzle containing a 45-degree core and a number four disc.

The sprayer was rized by C02, to 40 psi, and calibrated to deliver 100 gal per acre. Pre- treatment samples were taken on Day 1 and sampling ued weekly through 2 wks after the last application of treatments. Samples consisted of ten randomly selected leaflets per plot and were collected from the middle one-third stratum of the plants. Samples were transported to the tory where motile and egg TSM were brushed from the s onto ng sticky discs and counted on 1/ 10 of the disc surface to estimate average numbers per leaflet. Distinctions could not be made between viable and non-viable eggs, thus total eggs were recorded. MBI 206 at the highest rate (3 gal/acre) shows decrease in the number of eggs at a level comparable to at least two of the chemical controls.

A single treatment was delivered and compared to an untreated sample.

Mite counts were performed pre-treatment, and then at l, 7, 10 and 14 days after treatment.

Mite counts were an average of 10 fruits per treatment per sampling point. A reduction in the number of mites present in the MBI 206 treatments was observed at 14 days after ents with 1 and 2 gal/acre MBI 206 (approximately 6-8 mites per count), when compared to the untreated control (approx. 16 mites per count).

Example 16: Insecticidal (sucking contact) activity of Templamide, FR901465 and FR901228 against ed bugs.

The insecticidal activity of the pure compounds templamide B (MBI 206; MW 537), FR 901465 (MBI 206; MW 523) and FR901228 (MBI 206; MW 540) were tested in a laboratory assay using a sucking contact bioassay system. The compounds were dissolved in 100% l to concentrations of 1mg/mL. Individual 4th instar ed bugs, penultimate nymph, larvae were placed in 5C maid container with 2 sunflower seeds in each tub and 1 water cup (water in contact cup with cotton wick) into each tub. A Hamilton Micropipette was used to apply 1 ML (1 drop) of nd onto abdomen of ed bugs (MWB) of each larvae. Tubs were place into the Rubbermaid container and cap with mesh lid. Eight larvae per sample were treated. The assay was incubated at 25°C, 12h light/12h dark. Larvae were scored at 4 and 7 day after application. All the three nds exhibited contact activity against MWB, while not all insects died but many were clearly affected and unable to move. Most of the MWB on day 7 had molted which suggests that the compounds may inhibit molting or affect normal MWB development.

Thus, FR 901465 provided a better (87.5 %) control of milkweed bugs, than FR 901228 (MW 540) and templamide B (Figure 4).

Example 17: Insecticidal activity of pure compounds against Lygus hesperus late 2nd/early 3rd instar The insecticidal ty of the four compounds, templamide A, templamide B, FR901465 & FR901228 isolated from Burkholderia were tested in a tory assay using a 12 well plate with treated green beans bioassay system. The compound was dissolved in 100% ethanol to concentrations of 1 mg/mL and 500 ML of this sample was added to 3.5 mL of water to make a total volume of 4 mL containing 0.25 mg/mL concentration of the compound. Green beans were washed earlier in bleach on and then sat in water to rinse. Beans were dried before using and then were cut with rs to fit into wells of 12 — well plate. With the help of forceps the beans were dunked into a 15 mL plastic falcon tube containing each treatment and then submerged in treatment for exactly one min. one bean part was put into each well and then individual late 2nd/early 3rd instar Lygus us, were placed in wells with help of brush. Plate sealer was used to cover tray and hole poked into the plate sealer for aeration. The numbers of Lygus/well were counted and plates were placed on brench top. Larvae were scored at 24, 48 and 120 hours after application. Based on the results presented in Figure 5, compound FR 901465, was found to be the most potent with mortality of 91.2%, followed by templamide with B 69.2%, and FR901228 with 51.7%. The templamide A was inactive in the Lygus feeding bioassay. The positive control used in this testing was Avid (Avemectin) at the rate of 13 uL/10 mL.

Example 18: Nematicidal Activity of 28 The pure sample of FR 901228 was tested using an in vitro 96-well plastic cell- culture plate bioassay. 15-20 des in a 50 ul water solution were exposed to 3 ul of a mg/ml solution of FR 901228 for a 24 hour period at 25C. Once the incubation period was completed, results were recorded based on a visual grading of immobility of the juvenile des (J2’s) in each well treated with compounds; each treatment was tested in replicate of 4 wells. Three controls are included in each trial; 1 positive (1% Avid) & 2 negative (DMSO & water). Trials (T1) was carried out using Free living nematodes (FLN) and trail (T2) was carried out using M. incognita des, the samples were dissolved in 100% DMSO. FR 901228 (MW 540) showed the ent control with immobility of 75% against free living nematodes as compared to M. incognita with 75% immobility.
