摘要
Sediment microbial fuel cells (SMFCs) can convert sedimentary chemical energy into electricity and stimulate contaminant removal simultaneously. In the past two decades, SMFCs have attracted increasing attention in various disciplines, and several successful pilot tests of SMFCs in practical environments have been reported. Driven by concerns about energy and the environment, researchers from China have reported the most SMFC-related studies in recent years. Microbial energy and substrate metabolism play a key role in determining the power generation and contaminant degradation in SMFCs. However, the reported microbial electron transfer processes in SMFCs have not been well summarized or analyzed. Therefore, this review focuses on the microbial electron transfer networks on the electrode surfaces of SMFCs. The electron donors, microbial communities and functional genes near the anodes, and the electron acceptors and microbial communities on the cathodes are summarized and discussed. We also propose a prospect of SMFCs with an aim of providing helpful information and opinions for better development and application of SMFCs in the near future. © 2019, Science Press.
