1、Electricigens are a class of bacteria capable of metabolizing carbon sources and transferring electrons to extracellular electron acceptor.Pseudomonas, Geobacter and Shewanella are all well-known electricigens.Especially

2、, Shewanella, as a typical modal microorganism with relative clear gene sequence, has been widely investigated for pollutant degradation and electricity generation.In its metabolism, a wide range of substances can be ust

3、ilized as electron donors or acceptors under anaerobic conditions. Accompanied with the reduction of pollution, Shewanella could obtain energy for its growth.However, the electron transfer pathways of these processes are

4、 largely unclear.Therefore, in this work, S.oneidensis MR-1 and its mutant strains were used to investigate the bioreduction mechanisms of the organic pollutants, which are commonly present in natural environments.Furthe
