Abstract:

With the development of modern science and technology, especially due to application of molecular biology, the research on microbial diversity has been elevated to a higher level, the shortcomings of the traditional culture has been overcome and more considerable progress occurred in the analysis methods of diversity of microbial flora. In this paper, various research methods of diversity of microbial flora were presented in the following three parts: (1) traditional pure culture techniques; (2) modern molecular biology techniques; (3) the joint use of the above two methods, and the features and the prospect of these methods were focused on.

Key words: microorganism, flora, diversity, molecular biological methods
