Analysis of microbial populations in River-lake ecotone of Poyang Lake

摘要

Using the independent-cultivated molecular biology method, By Next-generation DNA sequencing techniques, Gene sequences of microbial groups for water samples collected from River-lake ecotone of Poyang Lake. water samples were collected form River-lake ecotone of Poyang Lake to determine gene sequences of microbial, using the independent-cultivated molecular biology method and Next-generation DNA sequencing techniques. The data showed that Poyang Lake had the largest number of unique microcal population, followed by the Yao River, the Ganjiang River, and the Rao River. The Species difference was smaller between samples in Ganjiang River and Rao River, while significant differences were found among Lake Poyang and the three other rivers. Poyang Lake was a huge microbial's genes pool, including a large number of the DNA sequence from ammonia oxidizing bacteria to animonia-oxidizing archare. It's expected to separate functional microorganisms which may play an important role in the earth nitrogen cycle.
