Description
【0001】
【発明の属する技術分野】
本発明は、藍藻を培養した後、さらに前記培養温度より高い温度に加熱して、藍藻に熱ショックを与えて改質した藍藻及び前記改質藍藻製造時の培養上清の新規機能に係る生理作用活性化剤に関する。
【0002】
【従来の技術】
従来、酵母を利用した代謝活性化剤の技術が開示されている(特表平10−505612公報)。しかしながら、酵母の活性成分の製造は煩雑であり、また酵母自体を培養するための培地も高価である。さらに、前記特表平10−505612公報においては、生理作用を確認したデータは示されておらず、その作用の程度、範囲も不明である。
【0003】
一方、近年植物系由来の代謝活性化剤等の生理作用活性化剤は依然として需要があるが、酵母は植物系由来ではない。また、植物系由来としてはクロレラの線維芽細胞増殖促進剤としての技術開示があるが(特開平10−36283公報)、その効果の程度は充分でない。
【0004】
さらに、熱安定性スーパーオキシドジスムターゼ(SOD)をシアノバクテリア等の光合成微生物を用いて産生させてこれを抽出する方法が開示されているが(特開平7−135970公報)、そのSOD活性は充分でない。
【0005】
【発明が解決しようとする課題】
本発明は上記事情に鑑みてなされたもので、その目的は、安価で、簡単に製造することができる、優れた生理作用活性を有する植物系由来の生理作用活性化剤を提供することにある。
【0006】
【課題を解決するための手段】
本発明者らは上記課題を解決するために鋭意研究を行った結果、藍藻に熱ショックを与えて改質した藍藻及び藍藻改質過程で得られる培養上清に、高活性の生理作用活性化機能があることを見出し、本発明を完成するに至った。
【0007】
すなわち、本発明は、藍藻を培養した後、さらに前記培養温度より高い温度に加熱して、藍藻に熱ショックを与えて改質した藍藻からなる生理作用活性化剤である。
【0008】
前記改質藍藻からなる生理作用活性化剤としては、SOD様活性剤、過酸化脂質生成抑制剤、線維芽細胞増殖促進剤、育毛剤、突然変異抑制剤が挙げられる。
【0009】
また、本発明は、藍藻を培地に懸濁させた培養液中で培養した後、さらに前記培養液を前記培養温度より高い温度に加熱した後、前記培養液を分離して得られる培養上清からなる生理作用活性化剤である。この生理作用活性化剤としては、線維芽細胞増殖促進剤が挙げられる。
【0010】
本発明において藍藻の最適培養温度とは、藍藻が指数的に増殖する最適な培養温度(培地の温度)である。
【0011】
本発明においては、SOD様活性、過酸化脂質生成抑制、育毛、突然変異抑制、線維芽細胞増殖促進等の作用を生理作用と称し、それらの生理作用機能を有するものを生理作用活性化剤と称する。
【0012】
【発明の実施の形態】
以下、本発明の実施形態について詳述する。
【0013】
本発明において、藍藻は公知の藍藻の中から選択され用いられる。藍藻としては、例えば、Synechococcus属、Synechocystis属、Cyanothece属、Choroococcus属、Gloeocapsa属、Microcystis属、Aphanocapsa属、Aphanothece属、Chamaesiphon属、Coelosphaerium属、Dactylococcpsis属、Eucapsis属、Gloeobacter属、Gloeothece属、Gomphosphaeria属、Holopedia属、Marssoniella属、Marssoniella属、Merismopedia属、Rhabdoderma属、Tetrapedia属等の藍藻が挙げられる。さらに、具体的には、Synechococcus
vulcanus、Synechococcus
elongatus、Synechococcus
sp.PCC7942、Synechocystis
sp.PCC6803、Cyanothece sp.BH68等が挙げられる。これらのうちで、Synechococcus属の藍藻、特に、Synechococcus vulcanus、Synechococcus elongatus、Synechococcus sp.PCC7942が好ましく用いられる。さらに好ましくは、Synechococcus
vulcanusである。
【0014】
本発明においては、藍藻を培養した後、さらに前記培養温度より高い温度に加熱して、藍藻に熱ショックを与えて改質した藍藻(以下、改質藍藻という。)、及び藍藻を培地に懸濁させた培養液中で培養した後、さらに前記培養液を前記培養温度より高い温度に加熱した後、前記培養液を分離して得られる培養上清が用いられる。
【0015】
藍藻は、まず通常の培養方法を用いて培養される。例えば、藍藻を培地中に懸濁させて培養する方法がとられる。培養は、該藍藻個々が有している最適培養温度で培養されることが好ましい。最適培養温度は、例えばSynechococcus
vulcanusは50〜55℃程度、Synechocystis PCC6803は30〜34℃程度、Synechococcus elongatusは50〜57℃程度である。
【0016】
培地としては、通常の藍藻を培養する培地、例えば無機培地が用いられる。培養は好気性条件下、光照射下で行うことが好ましい。
【0017】
本発明においては、藍藻を好ましくは藍藻の最適培養温度で培養を行った後、さらに前記培養温度より高い温度に加熱される(この工程を加熱工程という。)。培養温度の加熱によって増殖した藍藻は熱ショックを受け改質される。なお、加熱工程時にも培養が継続され(前記培養を第一段階の培養とすれば継続される培養は第二段階の培養となる。)、藍藻が増殖されるであろうが、このこと自体は本発明の目的とは関係することはない。前記加熱工程時の加熱温度は、第一段階の培養温度より高い温度であればよいが、第一段階の培養温度より5〜25℃高い温度が好ましい。さらに好ましくは10〜20℃高い温度である。
【0018】
前記加熱工程の培養時間は任意に設定できるが、2〜5時間が好適である。また、前記加熱工程時には、培養液に光照射と通気が行われることが好ましい。
【0019】
前記加熱工程後、培養培地から改質された藍藻を分離する。藍藻が懸濁された培養液を用いた場合は、必要に応じて冷却した後遠心分離などによって改質藍藻層と培養上清とに分けられ、改質藍藻を分離する。また、前記培養上清は後述するように藍藻とは別の生理活性もあるので分離して用いることができる。
【0020】
前記改質藍藻は、破砕され破砕物として、また溶媒により抽出され抽出物として用いることが効果を充分に発揮させるために好ましい。特に、破砕物として用いることが好ましい。破砕は機械的に破砕するのが好ましく、例えばミキサー、凍結破砕装置、コロイドミル等が用いられる。また、抽出は公知の溶媒を用いた抽出方法が用いられる。
【0021】
本発明における前記改質藍藻、前記培養上清には、後述するように、高活性の、過酸化脂質生成抑制、育毛、突然変異抑制、線維芽細胞増殖促進等の生理作用機能を有する。
【0022】
したがって、本発明は、前記の生理作用機能を有する生理作用活性化剤を提供するものである。この生理作用活性化剤は、生理作用活性化剤として活用できる他、種々の応用が可能であり、生理作用活性化剤を配合して医薬品、医薬品部外品を含む化粧品、飲食品等の組成物として前記機能を発揮させることができる。
【0023】
なお、前記改質藍藻は、特に線維芽細胞増殖促進作用とSOD様活性作用とを併せ持つので抗老化機能を有し、抗老化剤として活用できる。
【0024】
また、前記改質藍藻は熱安定性に優れ、例えば、70℃では1時間、75℃では40分間曝してもその強いSOD様活性等の生理活性は失われることはない。
【0025】
【実施例】
以下実施例を挙げて本発明を具体的に説明する。実施例の説明に先立ち本発明で用いた生理作用の測定方法について説明する。

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0013]
In the present invention, cyanobacteria are selected from known cyanobacteria. Examples of cyanobacteria include, for example, Synechococcus, Synechocystis, Cyanothece, Choroococcus, Gloeocapsa, Microcystis, Aphanocapsa, Aphanothece, Chamaesiphon, Coelosphaerium, Dactylococcpsis, Eucapsis, And cyanobacteria such as Holopedia, Marssoniella, Marssoniella, Merismopedia, Rhabdoderma, Tetrapedia, and the like. Furthermore, specifically, Synechococcus
vulcanus, Synechococcus
elongatus, Synechococcus
sp.PCC7942, Synechocystis
sp.PCC6803, Cyanothece sp.BH68 and the like. Among these, cyanobacteria belonging to the genus Synechococcus, particularly Synechococcus vulcanus, Synechococcus elongatus, Synechococcus sp. PCC7942 are preferably used. More preferably, Synechococcus
It is vulcanus.
[0014]
In the present invention, after cultivating cyanobacteria, it is further heated to a temperature higher than the above-mentioned culture temperature to give a heat shock to the cyanobacteria (hereinafter referred to as modified cyanobacteria), and the cyanobacteria are suspended in a medium. After culturing in a turbid culture solution, the culture solution is further heated to a temperature higher than the culture temperature, and then the culture supernatant obtained by separating the culture solution is used.
[0015]
The cyanobacteria are first cultured using a normal culture method. For example, a method is employed in which cyanobacteria are suspended in a medium and cultured. The culture is preferably performed at the optimum culture temperature possessed by each cyanobacteria. The optimal culture temperature is, for example, Synechococcus
Vulcanus is about 50-55 ° C, Synechocystis PCC6803 is about 30-34 ° C, and Synechococcus elongatus is about 50-57 ° C.
[0016]
As the medium, a medium for cultivating ordinary cyanobacteria, for example, an inorganic medium is used. Cultivation is preferably performed under light irradiation under aerobic conditions.
[0017]
In the present invention, cyanobacteria are preferably cultured at the optimum culture temperature of cyanobacteria, and then further heated to a temperature higher than the culture temperature (this step is referred to as a heating step). The blue-green algae grown by heating at the culture temperature are modified by heat shock. The culture is continued even during the heating step (if the culture is the first stage culture, the continued culture is the second stage culture), and the blue-green algae will grow. Is not related to the object of the present invention. The heating temperature in the heating step may be higher than the first stage culture temperature, but is preferably 5 to 25 ° C. higher than the first stage culture temperature. More preferably, the temperature is higher by 10 to 20 ° C.
[0018]
Although the culture time of the heating step can be arbitrarily set, 2 to 5 hours is preferable. Moreover, it is preferable that light irradiation and ventilation | gas_flowing are performed to a culture solution at the time of the said heating process.
[0019]
After the heating step, the modified cyanobacteria are separated from the culture medium. When a culture solution in which cyanobacteria is suspended is used, the modified cyanobacteria layer is separated into a modified cyanobacteria layer and a culture supernatant by cooling after cooling as necessary, and the modified cyanobacteria are separated. Moreover, since the culture supernatant has physiological activity different from cyanobacteria as described later, it can be used separately.
[0020]
The modified cyanobacteria are preferably crushed and used as a crushed product, or extracted with a solvent and used as an extract, in order to sufficiently exert the effect. In particular, it is preferably used as a crushed material. The crushing is preferably carried out mechanically, and for example, a mixer, a freeze crushing device, a colloid mill or the like is used. For extraction, a known extraction method using a solvent is used.
[0021]
As described later, the modified cyanobacteria and the culture supernatant in the present invention have highly active physiological functions such as lipid peroxide production inhibition, hair growth, mutation inhibition, and fibroblast proliferation promotion.
[0022]
Therefore, the present invention provides a physiological activity activator having the physiological function described above. The physiologically active activator can be used as a physiologically active activator and can be used in various applications. The physiologically active activator is combined with a physiologically active activator to make a composition such as pharmaceuticals, cosmetics including quasi-drugs, and foods and drinks. The said function can be exhibited as a thing.
[0023]
The modified cyanobacteria have both an anti-aging function and can be used as an anti-aging agent because they have both a fibroblast proliferation promoting action and an SOD-like activity action.
[0024]
Further, the modified cyanobacteria are excellent in thermal stability. For example, even when exposed to 70 ° C. for 1 hour and at 75 ° C. for 40 minutes, physiological activity such as strong SOD-like activity is not lost.
[0025]
【Example】
Hereinafter, the present invention will be specifically described with reference to examples. Prior to the description of the examples, the physiological action measurement method used in the present invention will be described.
[0026]
[Measurement of SOD-like activity]
An NBT aqueous solution, a 0.15% BSA aqueous solution, and a sample were mixed with 2.6 ml of a sodium carbonate-hydrochloric acid buffer solution containing xanthine and EDTA, and left at 25 ° C. for 10 minutes. Thereafter, the enzyme solution was added, and the absorbance at 560 nm of the reaction solution was measured 20 minutes after the start of the reaction, and the NBT reduction inhibition rate was calculated. The amount of O 2 − generated by the enzyme reaction was eliminated by reducing NBT, and the elimination ability was defined as SOD-like activity.
[0027]
[Measurement of lipid peroxide production inhibitory effect]
The inhibitory effect on the peroxidation of linolenic acid caused by ultraviolet rays was measured using the TBA method.
[0028]
[Measurement of fibroblast proliferation promoting effect]
In advance, we examined the FBS concentration at which cells (purchased from NB1RGB RIKEN Genebank) did not grow or decrease, confirmed that 0.5% FBS-MEM medium satisfies this condition, and promoted fibroblast proliferation only in the test sample The effect can be evaluated. The cells were seeded in a 35 mm dish using 1.5% FBS-MEM medium to a density of 1 × 10 5 cells / dish (2 ml) and cultured under conditions of 5% CO 2 and 37 ° C. for 24 hours. Thereafter, the culture medium was replaced with 0.5% FBS-MEM, and the sample was added so as to obtain an addition concentration of 10% at the maximum. After culturing for 9 days, the cells were counted with a Bürkerturk hemocytometer. A blank to which physiological saline was added was provided, and the number of cells in the blank was defined as 100, and the cell viability of the sample addition group was shown. As a control, 1.5% FBS-MEM was used. As for the culture supernatant, the medium was also measured to correct the corresponding action to be the action of the culture supernatant. The amount of sample added was 5%.
[0029]
[Measurement of hair growth action]
