Abstract：Lakes are important natural sources of methane (CH4) release. A well-known view is that frequent cyanobacterial blooms promote CH4 release in freshwater lakes, but the specific driving process and mechanism are still unclear. In this study, the driving process and effect of algal-derived organic matter deposition on CH4 release were simulated and studied by using water and sediment samples from Lake Chaohu. The results showed that the CH4 release flux in the group with the treatment of additional added algae was (1.59±0.51)~(98.89±14.30) μmol/(m2·h)) significantly higher than that in the control group (0.02±0.016)~(1.37±0.44) μmol/(m2·h)) (P<0.001). During the simulating experiment, the degradation of algal-derived organic matter provided a large number of substrates for methane production while the reduction of electron acceptors such as dissolved oxygen and sulfate created an environment conducive to methanogens, which resulted in a massive proliferation of methanogens, especially acetic acid trophic methanogens. Our study clearly demonstrated that the large input of algal-derived organic matter increased the methane production rate and methane release flux of lake sediments with acetic acid trophic methanogens playing an important role.
