Abstract
Mediums and protective agents of Bifidobacterium were screened for maximum viable count, which was the best to obtain maximum viable counts for Bifidobacterium bifidum BB-G90. Growth parameter of B. bifidum BB- G90 were confirmed by fermentation with controlled pH value of 5.0 ± 0.5. Results of the research showed that medi- um No. 3 was the best and the most appropriate protective agent of B, bifidum BB-G90 was No, 3. With controlled pH value of 5.0 ± 0.5 the viable cell number of B. bifidum BB-G90 could reach 1.80 ± 109 CFU/mL in the optimal growth medium at 37℃ for 22 h under anaerobic condition. Living bacteria content of B. bifidum BB-G90 powder were 4.10 ± 10n CFU/g after freeze-drying.关键词
