Phylogenetic identification of GO-reducing bacteria enriched from freshwater environments

This project conducted the phylogenetic identification of bacteria capable of respiration with an extracellular electron acceptor, graphene oxide (GO). GO is the oxidized form of graphene, a 2D honeycomb lattice of carbon. GO can be reduced to the reduced GO (rGO) by bacteria via extracellular electron transferring. Ant the rGO can facilitate the recovering electricity from bacteria. A variety of microorganisms potentially ability to reduce GO, while the reduction of GO was demonstrated by only Schewanella spp. This study enriched GO respiring bacteria from fresh water environments, and identified the enriched GO respiring bacteria by pyrosequencing targeting V4 region of 16SrRNA gene.
