Geobacter sulfurreducens can form electrically conductive biofilms, but the potential for conductivity through mixed-species biofilms has not been
examined. A current-producing biofilm grown from a wastewater sludge inoculum was highly conductive with low charge transfer
resistance even though microorganisms other than Geobacteraceae accounted for nearly half the microbial community.

    ABSTRACT: Two competing models for long-range electron transport through the conductive biofilms and nanowires of Geobacter sulfurreducens exist. In one model electrons are transported via pili that possess delocalized electronic states to function as protein wires with metallic-like conductivity. In the other model electrons are transported by more traditional electron transfer via electron hopping/tunneling between the c-type cytochromes in G. sulfurreducens biofilms and pili. The cytochrome hypothesis was further examined. Quantifying c-type cytochromes in G. sulfurreducens biofilms and pili indicated that there are insufficient cytochromes to account for electron transport through the bulk of the biofilm or pili and demonstrated that there is a negative correlation between cytochrome abundance and biofilm conductivity. Direct imaging using atomic force microscopy revealed that cytochromes were not packed close enough on pili to permit electron hopping/tunneling along the pili. Inactivating cytochromes had no impact on biofilm conductivity. The results of electrochemical gating studies were inconsistent with electron transport via cytochromes. Theoretical considerations suggest that a cytochrome model cannot explain the previously reported response of biofilm conductivity to temperature changes. These multiple lines of evidence, which rely on approaches with different sets of assumptions, demonstrate that the hypothesis that long-range electron transport through G. sulfurreducens biofilms and nanowires can be attributed to electron hopping/tunneling between c-type cytochromes is incorrect. In contrast, these multiple lines of evidence are consistent with long-range electron transport through the biofilms via networks of pili that possess metallic-like conductivity.

    ABSTRACT: Geobacter species are important Fe(III) reducers in a diversity of soils and sediments. Mechanisms for Fe(III) oxide reduction have been studied in detail in Geobacter sulfurreducens, but a number of the most thoroughly studied outer surface components of G. sulfurreducens, particularly c-type cytochromes, are not well conserved among Geobacter species. In order to identify cellular components potentially important for Fe(III) oxide reduction in Geobacter metallireducens, gene transcript abundance was compared in cells grown on Fe(III) oxide or soluble Fe(III) citrate with whole-genome microarrays. Outer-surface cytochromes were also identified. Deletion of genes for c-type cytochromes that had higher transcript abundance during growth on Fe(III) oxides and/or were detected in the outer-surface protein fraction identified six c-type cytochrome genes, that when deleted removed the capacity for Fe(III) oxide reduction. Several of the c-type cytochromes which were essential for Fe(III) oxide reduction in G. metallireducens have homologs in G. sulfurreducens that are not important for Fe(III) oxide reduction. Other genes essential for Fe(III) oxide reduction included a gene predicted to encode an NHL (Ncl-1–HT2A–Lin-41) repeat-containing protein and a gene potentially involved in pili glycosylation. Genes associated with flagellum-based motility, chemotaxis, and pili had higher transcript abundance during growth on Fe(III) oxide, consistent with the previously proposed importance of these components in Fe(III) oxide reduction. These results demonstrate that there are similarities in extracellular electron transfer between G. metallireducens and G. sulfurreducens but the outer-surface c-type cytochromes involved in Fe(III) oxide reduction are different.

    ABSTRACT: Microbes have been shown to naturally form veritable electric grids in which different species acting as electron donors and others acting as electron acceptors cooperate. The uptake of electrons from cells adjacent to them is a mechanism used by microorganisms to gain energy for cell growth and maintenance. The external discharge of electrons in lieu of a terminal electron acceptor, and the reduction of external substrates to uphold certain metabolic processes, also plays a significant role in a variety of microbial environments. These vital microbial respiration events, viz. extracellular electron transfer to and from microorganisms, have attracted widespread attention in recent decades and have led to the development of fascinating research concerning microbial electrochemical sensors and bioelectrochemical systems for environmental and bioproduction applications involving different fuels and chemicals. In such systems, microorganisms use mainly either (1) indirect routes involving use of small redox-active organic molecules referred to as redox mediators, secreted by cells or added exogenously, (2) primary metabolites or other intermediates, or (3) direct modes involving physical contact in which naturally occurring outer-membrane c-type cytochromes shuttle electrons for the reduction or oxidation of electrodes. Electron transfer mechanisms play a role in maximizing the performance of microbe–electrode interaction-based systems and help very much in providing an understanding of how such systems operate. This review summarizes the mechanisms of electron transfer between bacteria and electrodes, at both the anode and the cathode, in bioelectrochemical systems. The use over the years of various electrochemical approaches and techniques, cyclic voltammetry in particular, for obtaining a better understanding of the microbial electrocatalysis and the electron transfer mechanisms involved is also described and exemplified.
