牛奶中细菌生态演变及其保鲜与加工

Ecological Bacteria Evolution and Its Application on Keep Fresh and Process in Milk

对刚采集的生牛乳进行试验室培养。由于不同细菌所要求的生化条件不同,因此可以观察到牛乳在自然发酵与酸败过程中细菌由一种微生物群体接替另一微生物群体的一系列生态演变过程。以此确定最佳的牛奶保质与加工方法。

The fresh dairy which contains few kinds of bacteria, is cultured in the lab. Because different bacteria require different biochemical conditions,a series ecological developing process such as natural fermentation and turning sour during which courses the bacteria groups changing as one kind of microbe takes place of another kind of microbe are observed.
