JPH0674196B2 - Vinegar yeast fertilizer - Google Patents

Description

TECHNICAL FIELD The present invention relates to a vinegar-yeast fertilizer characterized by using vinegar-yeast as a fertilizer, which is hardly used as industrial waste at present.

(Prior Art) Vinegar yeast is a residue discharged during vinegar production, contains a large amount of water, is difficult to handle, and is only slightly used as an additive for feed. The present inventors paid attention to the components contained in vinegar yeast and tried to use them as fertilizers, but the results of the plant growth test were poor.

(Problems to be solved by the invention) Then, further studies were conducted, and when vinegar yeast was fermented and used as a fertilizer, favorable results were obtained and the present invention was completed.

(Means for Solving the Problem) That is, the present invention relates to a vinegar yeast fertilizer comprising fermenting vinegar yeast and then using this as a fertilizer.

(Crop) Vinegar is generally steamed rice or wheat, then saccharified and fermented.
For alcohol fermentation, rice koji and yeast are added and fermented, and then pressed.

The squeezed filtrate is produced by adding alcohol to heat, further adding vinegar seeds for acetic acid fermentation, and aging this.

The vinegar yeast used in the present invention is a residue generated during the production of vinegar, and is a yeast-rich residue generated in the pressing step after saccharification and alcohol fermentation.

The fertilizer of the present invention is obtained by adding a fermenting bacterium to this vinegar yeast and fermenting it. As for the fermentation method, as a fermenting bacterium that is generally commercially available in vinegar yeast, Bimefood (manufactured by Shimamoto Microorganism Co., Ltd.) , Product name), Arzeron (manufactured by Nippon Life Co., Ltd., product name), etc., and mixed well.
~ Ferment for about 10 days.

In the fermentation, the product temperature rises to about 50 ° C. until it is released after mixing the fermenting bacteria, so maintaining this for about 5 days is sufficient for improving the quality of vinegar yeast.

The vinegar yeast thus obtained is an extremely excellent fertilizer.

The vinegar yeast fertilizer of the present invention can also be used as a mixture with a general inorganic fertilizer salt or the like.

(Examples) Hereinafter, the present invention will be further described with reference to Examples, but the present invention is not limited thereto. All percentages are by weight unless otherwise specified.

Example 1 1000 kg of a vinegar-yeast residue wet cake (water content 67%) generated from the brewing vinegar production process was treated at 90 ° C. for about 1 hour using a drum dryer in order to sterilize and adjust the water content. The water content was adjusted to about 45%.

The processed vinegar yeast is cooled until the product temperature reaches about 50 ° C, and this is used as a fermentation bacterium by Bimefood (Shimamoto Microorganism Co., Ltd.).
1kg of product, trade name) was added and mixed thoroughly, and then put in a cloth container bag to start fermentation.

Fermentation proceeds with fever, and the temperature of vinegar yeast is about 50 ° C.
Was maintained at.

In order to stop the fermentation and adjust the water content 7 days after the start of fermentation,
This was dried at about 90 ° C. for 3 hours using a drum dryer to obtain the vinegar yeast fertilizer of the present invention.

For comparison, 1000 kg of the same wet cake of vinegar yeast residue (water content 67%) was similarly dried to adjust the water content to about 12%. (Comparative Example: Unfermented Product) Table 1 shows the analytical values of the fertilizer components of the fertilizer of the present invention and the comparative example product.

Using these fertilizers, a plant damage test and a fertilization test were conducted. The test methods and test results are described below.

(Vegetation damage test) 500 ml of air-dried soil (Kakogawa alluvial soil) was placed in each Neubawell pot, and the fertilizer of the present invention and the comparative example product were added thereto in the amounts shown in Table 2 to sufficiently prepare soil. Mixed.

After proper irrigation, 20 seeds of Komatsuna seeds were sown in each pot to cover the soil.

Place these in the dark until germination, 14 hours photoperiod after germination,
It was grown at a temperature of 20 to 25 ° C.

The germination and growth state from the seeding day were observed, and harvested 22 days later to investigate the growth state. The survey results are shown in Table 3.

As is clear from the results in Table 3, the unfermented vinegar yeast (comparative example product) is found to be unusable as a fertilizer because both germination and growth are impaired, and the vinegar yeast fertilizer of the present invention is It can be seen that it is suitable as a fertilizer, showing normal germination and growth in any of the four-fold amount from the standard amount.

(Fertilization test) Using the vinegar yeast fertilizer of the present invention and the above unfermented product for comparison, a tomato cultivation test was conducted under the following conditions.

Cultivation conditions are as follows.

Test site: Kobe City, Hyogo Prefecture Cultivated house Species: Mizuken Seeding date: September 20 Planting date: November 20 Harvesting: Mid-March to early May Fertilization: fertilizer of the present invention, comparative product and inorganic The fertilizer salt was divided into each group (3 groups), and fertilization was performed under the conditions shown in Table 4.

The results of the cultivation test are shown in Table 5.

As is clear from the results in Table 5, the vinegar yeast fertilizer application zone of the present invention has a large yield and good quality, and is excellent as an organic fertilizer. It can be seen that the application area of No. 1 is inferior in yield and quality to the application area of the inorganic fertilizer salt and is not suitable as a fertilizer.
