Abstract:
Objectives:For selecting finest probiotics can be applied to lactobacillus beverages.Methods:120 strains of
Lactobacillus casei isolated from fermented foods of Yunnan provice were studied,for obtaining
Lactobacillus caseis that can adapt to simulated digestive tract environment,inhabite intestinal pathogenic bacterias. Then,they are used in fermentation experiment of brown production of active lactobacillus drink.Conclusion:we screen out 4 strains of
Lactobacillus casei including
L.casei1,
L.casei2,
L.casei3,
L.casei5 with strong tolerance to simulated gastric fluid,man-made digestive juice and bile salt,the four strains of
Lactobacillus casei have antagonistic activity against the intestinal pathogenic bacterias,sothey have probiotic potential adjusting the balance of intestinal flora.
L.casei1,
L.casei2,
L.casei3,
L.casei5 can satisfy the production requirements through fermentation experiments of brown production of active lactobacillus drink.
