Variations of bacterial community during the decomposition of Microcystis under different temperatures and biomass
Abstract Background The decomposition of Microcystis can dramatically change the physicochemical properties of freshwater ecosystems. Bacteria play an important role in decomposing organic matters and accelerating the cycling of materials within freshwater lakes. However, actions of the bacterial co...
