Optimization of industrial medium for multi-bacteria complex sauerkraut fermentation agent
摘要
Abstract
In order to meet the requirements of industrial production,this article optimized the fermentation medium of multi-bacteria complex sauerkraut fermentation agent using cheap raw materials. Mono-factor tests and orthogonal experimental design were used to select the optimal amount of different components in the medium based on the mixed fermentation. Considering the biomass yield and product yield factors,the optimal combination of medium was determined as follows..2.5% corn saccharification solution,1.5% soybean meal hydrolyzate,0.5% corn steep liquor,2g/L K2HPO4,0.5g/L MgSO4,20mg/L MnSO4,under which the number of viable cells was 2,06× 10^9CFU/mL. The ratio of strains was Lactobacillus paracasei(L1 ):Lactobacillus buchneri (L5):Bacillus coagulans(B.c)=1:2.12:2.87,which was very close to the expected proportions of the three strains as determined in our lab previously.关键词
