TI  - Geobacter, Anaeromyxobacter and Anaerolineae populations are enriched on anodes 
      of root exudate-driven microbial fuel cells in rice field soil.

AB  - Plant-based sediment microbial fuel cells (PMFCs) couple the oxidation of root 
      exudates in living rice plants to current production. We analysed the composition 
      of the microbial community on anodes from PMFC with natural rice field soil as 
      substratum for rice by analysing 16S rRNA as an indicator of microbial activity 
      and diversity. Terminal restriction fragment length polymorphism (TRFLP) analysis 
      indicated that the active bacterial community on anodes from PMFCs differed 
      strongly compared with controls. Moreover, clones related to Deltaproteobacteria 
      and Chloroflexi were highly abundant (49% and 21%, respectively) on PMFCs anodes. 
      Geobacter (19%), Anaeromyxobacter (15%) and Anaerolineae (17%) populations were 
      predominant on anodes with natural rice field soil and differed strongly from 
      those previously detected with potting soil. In open circuit (OC) control PMFCs, 
      not allowing electron transfer, Deltaproteobacteria (33%), Betaproteobacteria 
      (20%), Chloroflexi (12%), Alphaproteobacteria (10%) and Firmicutes (10%) were 
      detected. The presence of an electron accepting anode also had a strong influence 
      on methanogenic archaea. Hydrogenotrophic methanogens were more active on PMFC 
      (21%) than on OC controls (10%), whereas acetoclastic Methanosaetaceae were more 
      active on OC controls (31%) compared with PMFCs (9%). In conclusion, electron 
      accepting anodes and rice root exudates selected for distinct potential 
      anode-reducing microbial populations in rice soil inoculated PMFC.
