Title: Identification of Lactic Acid Bacteria and Viable Count for Fermented Milk
Abstract: Objective To learn more about the qualitative and quantitative detection of lactic acid bacteria from fermented milk in Beijing.Method The count of viable lactic acid bacteria and the species of lactic acid bacteria in fermented milk were identified.Results The detection rate of Bifidobacterium,Lactobacillus acidophilus,Lactobacillus bulgaricus,Streptococcus thermophilus were 23.08%,27.27%,72.22%,94.44%,respectively.By the end of shelf-life,the average count of viable Streptococcus thermophilus,Lactobacillus bulgaricus,Bifidobacterium and Lactobacillus acidophilus were 3.23×106 CFU/ml,4.17×105 CFU/ml,1.12×104 CFU/ml and 1.32×104 CFU/ml,respectively.Conclusion The identifications and enumerations of viable Streptococcus thermophilus and Lactobacillus bulgaricus were more higher than those of Bifidobacterium and Lactobacillus acidophilus.
