ABSTRACT Decomposition of Cyanobacterial blooms frequently occurs in Lake Taihu, releasing various fractions algal organic matter into the water through cell lysis. These influence production and consumption dissolved matter, nutrient dynamics, bacterial succession lake. However, interactions between free‐living particle‐attached communities with different remain poorly understood. Herein, we investigated effects two distinct fractions, obtained a fractionation procedure simulating cyanobacterial bloom collapse, on freshwater communities. The degradation both resulted stage‐specific changes chemical properties lake water, which were divided stages (labeled Stage I II). Flavobacteriaceae was dominant I, whereas Methylophilaceae dominated II. Long‐term ecological observations indicated that bacteria responded more sensitively to than bacteria. Compared algal‐derived filtrate, breakdown residual exudative led complex community network. findings provide new insights capacity utilize highlight their roles aquatic ecosystems during post‐bloom stage.
