Objective: On the basis of national standard GB 4789.35-2016, a comparative study was conducted on dilution ratio, diluent components and medium components to investigate the influence on the number of viable bacteria when counting lactic acid bacteria powder. Nine strains of Lactobacillus, six strains of Bifidobacterium, three strains of coccus and one strain of Bacillus coagulans were used as research objects. Methods: The method of dilution plate count was used to count the viable bacteria of different lactic acid bacteria powders. Results: According to research findings, the dilution ratio of the initial lactic acid bacteria powder sample had no significant effect on the final count of viable bacteria, and the ISO dilution had significant effects on the viable count results of some Lactobacillus and Bifidobacterium powders (P |
