Distribution of anode-respiring microorganisms in the Sediments from Different Regions of Lake Taihu
Microbial fuel cell (MFC) was a device that directly converts microbial metabolic power into electricity through electrochemical technology. Anoderespiring microorganisms can completely oxidize organic compounds with electrode as sole electron acceptor and then transfer the electrons derived from that oxidation onto the anode of a MFC through electron transport chain.Some anode-respiring microorganisms were isolated from activated sludge and marine sediments,but less reported for freshwaster environments and their distribution.In this study,single-chamber microbial fuel cells were constructed by using glucose as the electron donor and sediment samples taken from different regions of lake Taihu as the inoculum. Through a period of enrichment,voltage was detected in MFCs,indicated that anode-respiring microorganisms existed in sediment of Lake Taihu. This study also showed spatial variance of anode-respiring microbial communities.Reasons of the difference were in-depth discussed by analyzing physical- chemical and microbial properties of different sediments.
