摘　　要：对乳酸菌生长培养基的组成、菌体细胞的离心条件和冷冻干燥介质选择等工艺条件进行了研究。制备的浓缩发酵剂含活菌数 3.0× 10 10 CFU/ g以上 ,可直接作为生产发酵剂用于酸奶生产的接种 ,接种量为 0 .0 1%～ 0 .0 3% ,比传统发酵剂接种量缩小 10 0倍以上 ,具有较好的发酵产酸活性 ,发酵产品质量良好。The composition of the lactic acid bacteria growth medium,centrifuging condition of the bacterium cells and selection of cryogenic medium were studied .The viable cells of the con- centrated starter culture were more than3.0× 1 0 1 0 CFU/ g.The amountof the starter inocula- tion can be reduced 1 0 0 times when used in producing yoghurt,still keeping high acid- pro- ducing activity.
