Abstract:
PURPOSE: An antagonistic microorganism Bacillus subtilis CP220 is provided, which or 0.1-50% cultured broth of which inhibits growth of aflatoxin-producing fungi, or decomposes aflatoxin. Fermented soybean food and animal feed-stuff containing the Bacillus subtilis CP220 are also provided. CONSTITUTION: A method of isolating and identifying antagonistic microorganism, Bacillus subtilis CP220, from soil reagent or customary fermented soybeans comprises the steps of: mixing the reagent with tris-HCl buffer solution(pH 7.5); inoculating the mixture into a nutrient broth, and culturing at 20-30°C for 20-40minutes; taking some of the cultured solution, and diluting with saline(0.85% NaCl) step by step; smearing each diluted solution on a nutrient agar, culturing at 20-30°C for 3days, and isolating colony; inoculating the Aspergillus flavus and the Aspergillus parasiticus on potato dextrose agar and culturing at 20-30°C for a day; inoculating the antagonistic microorganism at four positions around the culture medium and culturing continuously; selecting the bacillus that form inhibition zone after culturing for 7days; selecting the most superior antagonistic microorganism and identifying it as the Bacillus subtilis CP220.

Abstract:
PURPOSE: Provided is a method for manufacturing an improved functional beverage made of soybean paste by adding chitosan and chitooligosaccharide, for globalization of the traditional fermented food. CONSTITUTION: A method for manufacturing an improved functional beverage made of soybean paste is characterized by the following steps: i) manufacturing a soybean paste by using Bacillus subtilis CHO99 (KCTC-18052P) which does not smell during fermentation; ii) adding 1.0-4.0wt% of water to the soybean paste; iii) liquefying the paste with one enzyme selected from alpha-amylase, beta-amylase, and cellulase and fermenting the liquefied paste with yeast; and iv) adding sweeteners and spices to 3.0-50.0wt% of water.
Abstract:
본 고안은 의복용 후크에 관한 것으로서 종래에는 암.수후크에 있는 봉접링의 구경이 서로 달라 암.수 후크를 고정시키기 위하여 박음질시 봉접링의 구경에 따라 세팅작업을 달리하여야 하므로 작업시간이 오래걸리는 것은 물론 암후크의 봉접링과 봉접링 사이가 서로 떨어져 있어 강도가 약한 문제점이 있는 것이다. 따라서 본 고안은 한쌍의 봉접링(12a)(12b)과 고리(11)로 암후크(10)를 형성하고, 한쌍의 봉접링(22a)(22b)과 걸림구(21)로 수후크(20)를 구성함에 있어서,철판을 프레싱하여 상기 암후크(10)와 수후크(20)를 형성하되 상기 암후크(10)의 봉접링(12a)(12b)과 고리(11)가 중앙의 보강살(13)에 의해 서로 연결되게 하고, 상기 수후크(20)의 봉접링(22a)(22b)과 걸림구(21)도 중앙 보강살(23)에 의해 서로 일체로 연결되게 형성한 것으로서 이러한 본 고안은 봉접링의 규격이 모두 같으므로 후크를 박음질로 고정시 재봉틀의 세팅작업을 한번만 하면 되므로 작업시간을 단축한 것은 물론 암후크의 고리와 양 봉접링이 모두 보강살로 이어져 있어 그만큼 강도가 향상되어 고리의 형태가 변형되는 것을 효과적으로 방지토록 한 매우 유용한 고안이다.
Abstract:
PURPOSE: A microbial preparation added to feedstuff of livestock and used for the treatment of excreta of livestock is provided, thereby preventing diarrhea of livestock and decreasing BOD of the excreta of livestock. CONSTITUTION: The microbial preparation added to feedstuff of livestock and used for the treatment of excreta of livestock comprises 10 to 70 wt.% of Azospirillum sp. (KCTC 8989P), 1 to 60 wt.% of Streptococcus thermophilus (KCTC 8988P) and 1 to 60 wt.% of Bacillus subtilis (KCTC 8990P). The yeast and Corynebacterium glutamicum (KCTC 3339) can be further added into the microbial preparation when it is added into livestock feedstuff. The Rhodospirillum rubrum (KCTC-1372), Thiobacillus denitrificans (KCCM 31224) and Nitrosomonas europaea (KCTC 2704) can be further added into the microbial preparation when it is added into the livestock feedstuff.
Abstract:
PURPOSE: A method for preparing a heathy food using fermented beans or powdered fermented beans is provided, which can be applied to various foods such as bread, biscuit, cake, or confectionery. CONSTITUTION: A method for preparing a heathy food using fermented beans comprises the steps of: (i) a first step to inoculate Bacillus subtillisCHO99 into beans, ferment for 12-36 hours to prepare odorless fermented beans; (ii) a second step to add sweetening agents, acidulant, and spice and dry for its water content to reach 8-40% in the normal temperature; (iii) a third step to powder dried fermented beans; (iv) a fourth step to mix the fermented bean powder 100wt.% with one or more seaweed powder 5-100wt.% selected from tangleweed, brown seaweed, agar, Hizikia fusiforme, or Enteromorpha, glucose 2-20wt.%, sugar 2-20wt.%, fructose 2-20wt.%, and a small amount of salt, acidulant, and spice, or an alternative step to mix the fermented bean powder 100wt.% with one or more powders 5-100wt.% selected from Jobs-tear powder, corn powder, rice powder, or buckwheat powder instead of seaweed powder; and (v) a fifth step to add other materials as ends, and then knead, and prepare various foods.
