摘　　要：用经过耐氧驯化后的两歧双歧杆菌发酵牛初乳,研究了其发酵特性。结果表明,两歧双歧杆菌在牛初乳中37℃发酵10h,pH值为4.72,活菌数为3.3×109mL-1,初乳IgG活性、质量浓度基本保持不变。Using colotrums was fermented by oxygen-resistant B.bifidum,and its fermentation characteristics were studied.The results showed that colostrums was fermented by B.bifidum at 37 ℃ after 10 h,when pH value was 4.72,the amount of B.bifidum came to 3.3×10^9 cfu/mL, respectively,and the activity and amount of IgG in colostrums kept steady.
