CHEN Yan-fei(Department of Biology, Taiyuan Teachers College, Taiyuan 030012, China)
The fresh dairy which contains few kinds of bacteria, is cultured in the lab. Because different bacteria require different bio-chemical 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.
