英文摘要Many electroactive microorganisms (EAMs) are known as dissimilatory iron-reducing bacteria (DIRB) which can access iron as an electron acceptor to transfer electrons during the process of respiration. Previous research has shown that magnetic susceptibility (chi lf) could be used as an indicator of DIRB activities. However, the relationship between chi lf and electroactivity of EAMs is still unclear. Here, we report that after sediments of the Sha River enriched with amorphous iron, the chi lf of enrichment cultures increased dramatically. The reactor inoculated with higher chi lf enrichment cultures started earlier and had a higher peak voltage (0.228 V), higher power density (310.14 mW m(-2)) and higher coulombic efficiency (10.16%) than lower chi lf cultures. Sequencing of bacterial 16S rRNA gene amplicons and chi lf measurement revealed that relative abundance of dominant phyla Proteobacteria increased with chi lf values in sediments. Further analysis of cyclic voltammetry curves and bacterial terminal-restriction fragment length polymorphism (T-RFLP) of bacterial rRNA genes indicated that the improved performance of the MFCs might be due to a highly electroactive microbial community that the 162 bp terminal restriction fragments (TRFs) originated from. Our results suggested a potential correlation between chi lf and presence of EAM indicating a promising route for fast screening in complex environments.
