枯草芽孢杆菌J-4菌株产抑菌物质发酵条件优化
Optimization of Fermentation Conditions for Producing Antibacterial Substance from Bacillus subtilis Strain J-4
摘要
Abstract
In order to improve the content of antibacterial substance in the fermentation broth of Bacillus subtilis strain J-4,the combined method of single factor test and orthogonal test was used to optimize the factors,such as carbon source,nitrogen source,inorganic salts,fermentation time,media amount,fermenta-tion temperature and inoculation amount. The medium composition and fermentation conditions after opti-mization were as follows:glucose 1%, soybean cake powder 1%, MgSO40. 15%, Na2 HPO40. 10%, NaH2PO40. 10%,fermentation time 36 h,media amount 100 mL(250 mL),fermentation temperature 37 ℃,inoculation amount 5%. The inhibition area after optimization increased by 50. 25% compared with the inhibition area when using the basal fermentation medium.关键词
