Effects of algal bloom (AB) on sediment microorganisms with special functions at different AB stages in Chaohu Lake

Algal bloom (AB) is a serious water environment problem in China, but it is still unclear how AB affects microorganisms with special functions (such as nitrogen-, phosphorus-, sulfur- and iron-related bacteria) at different AB stages. Samples of water and sediment were taken in the AB region and fre...
