Influence of galactooligosaccharides on the growth and metabolism of Lactobacillus plantarum
摘要
Abstract
In Lactobacillus plantarum KLDS1.0391 which can produce the bacteriocins,the effect of galactooligosaccharides (GOS) which substituted for glucose in MRS media were studied in vitro fermentation.The titratable acidity,pH value and amounts of viable bacteria were determined during fermentation of 36 h at 37 ℃ in both of MRS and mMRS(GOS substituted for glucose).The contents of organic acids and bacteriocins were also determined at the cultivation of 28 h and 24 h respectively.The results showed that the pH value decreased rapidly with the cultivation and then changed sloely after cultivation of 12 h,and the growth-stimulating effect of galactooligosaccharides (GOS) was significantly higher than that of glucose (p ＜ 0.05),meanwhile the decline was slower.Moreover,the concentrations of organic acids and antimicrobial activity of the bacteriocins in mMRS were higher than that in MRS,and the main organic acids were lactate,acetate and propionate.关键词
