Changes In Bacterial Community Structure Of A Hypertrophic Freshwater Lake Taihu, Determined By Denaturing Gradient Gel Electrophoresis Fingerprint

Lake Taihu, the third-largest lake in People's Republic of China, is a typical shallow freshwater lake. Due to agricultural intensification and excessive exploitation, its trophic status was increasingly getting aggravated. Water quality was getting worse and the ecosystem was declining. In nature, there are extraordinary relationships among microorganisms and between microorganisms and environments. Due to the lack of cultured bacteria in aquatic ecosystems, the diversity of bacterial communities has not been extensively studied. However, developments in molecular biological technology bring a new path for scientists to investigate bacterial communities. In order to describe a complete picture of the structure of bacterial communities in a hypertrophic freshwater lake, PCR-DGGE method was applied to study water samples from Lake Taihu.Water samples were collected with different locations (Eastern, southern...
