Abstract: PURPOSE: A microorganism capable of producing a heat-tolerant antimicrobial peptide, derived from Korean salted sea foods is provided, which antimicrobial peptide has a strong antimicrobial activity against various plant or animal pathogenic bacteria. CONSTITUTION: The microorganism Bacillus subtilis JKK238 being isolated from Korean salted sea foods is capable of producing a heat-tolerant antimicrobial peptide which has a strong antimicrobial activity to known pathogenic fungi consisting of Pyricularia oryzae, Botrytis cinera, Penicillium sp. Fusarium oxysporum, Collectotrichum cocodes, Phytophthora crytogea and Rhizoctonia solani, and other microorganisms of Streptomyces scabies, Erwinia caractovora and Listeria monocytogenes. The heat-tolerant antimicrobial peptide may be added into feeds, foods or agricultural chemicals to inhibit the growth of the pathogenic fungi and other microorganisms.

Abstract: PURPOSE: A freshness maintaining goods using polyglutamic acid(PGA) from Bacillus subtilis is provided, which extend the term of validity and storage of vegetables and fruits by inhibiting growth of fungus or bacteria. CONSTITUTION: A process for the preparation of freshness maintaining goods using polyglutamic acid comprises the steps of: inoculating Bacillus subtilis TB11(KFCC-11025) into the GA medium, shake-culturing at 28deg.C, 170rpm for 3days, and centrifuging the cultured solution at 10,000xg for 20minutes; adding three times of ethanol in volume to the supernatant, and keeping at 4deg.C for a night; precipitating white gelatinous material by centrifuging at 7,000xg for 15minutes, dissolving the precipitate in distilled water, and dialyzing at 4deg.C for 3days while replacing the distilled water on occasion; and freeze-drying to get polyglutamic acid powder.
Abstract translation: 目的：提供使用来自枯草芽孢杆菌的聚谷氨酸（PGA）的保鲜产品，通过抑制真菌或细菌的生长来延长蔬菜和水果的有效期和储存期。 构成：使用聚谷氨酸制备保鲜品的方法包括以下步骤：将芽孢杆菌TB11（KFCC-11025）接种到GA培养基中，以28℃，170rpm摇动培养3天，离心培养的溶液 10,000xg 20分钟; 向上清液中加入3倍体积的乙醇，并保持在4℃下一夜; 通过以7,000xg离心15分钟沉淀白色凝胶状物质，将沉淀物溶解在蒸馏水中，并在4℃下透析3天，有时更换蒸馏水; 并冷冻干燥得到聚谷氨酸粉末。
