摘要: The effect of some materials including sucrose, peptone and yeast extract on growth B. longum B.adolescentis in the Fructus tribuli was studied by measuring optical density at 600nm (OD600) pH. addition 0.0%-2.40%, 0-1.4% 0-1.4%, respectively. Results were as follows: could promote B.adolescentis. optimum concentration 2.0%, 1.0% for 2.20%, 0.8%
