Enhancement of methanogenesis by electric syntrophy with biogenic iron‐sulfide minerals

MicrobiologyOpen, 2019
Recent studies have shown that interspecies electron transfer between chemoheterotrophic bacteria and methanogenic archaea can be mediated by electric currents flowing through conductive iron oxides, a process termed electric syntrophy. In this study, we

Aromatic Amino Acids Required for Pili Conductivity and Long-Range Extracellular Electron Transport in Geobacter sulfurreducens

mBio, 2013
It has been proposed that Geobacter sulfurreducens requires conductive pili for long-range electron transport to Fe(III) oxides and for high-density current production in microbial fuel cells. In order to investigate this further, we constructed a strain

Community analysis of biofilms on flame-oxidized stainless steel anodes in microbial fuel cells fed with different substrates

BMC Microbiology, 2017
Background The flame-oxidized stainless steel anode (FO-SSA) is a newly developed electrode that enhances microbial fuel cell (MFC) power generation; however, substrate preference and community structure of the biofilm developed on FO-SSA have not been ...

Rational engineering of Geobacter sulfurreducens electron transfer components: a foundation for building improved Geobacter-based bioelectrochemical technologies

Frontiers in Microbiology, 2015
Multiheme cytochromes have been implicated in Geobacter sulfurreducens (Gs) extracellular electron transfer (EET). These proteins are potential targets to improve EET and enhance bioremediation and electrical current production by Gs.

Possible role of Geobacter sulfurreducens in anaerobic corrosion of steels [PDF]

, 2007
Geobacteraceae are the most widespread microorganisms in soils and sediments in which microbial reduction of Fe(III) is an important process, either in the natural degradation of organic compounds or in their bioremediation.

Electromicrobiology: Electron Transfer via Biowires in Nature and Practical Applications

BIO Web of Conferences, 2016
One of the most exciting developments in the field of electromicrobiology has been the discovery of electrically conductive pili (e-pili) in Geobacter species that transport electrons with a metallic-like mechanism.

Extracellular electron transfer mechanism in Shewanella loihica PV- 4 biofilms formed at indium tin oxide and graphite electrodes [PDF]

, 2013
Electroactive biofilms are capable of extracellular electron transfer to insoluble metal oxides and electrodes; such biofilms are relevant to biogeochemistry, bioremediation, and bioelectricity production.

Microbes, cables, and an electrical touch [PDF]

, 2016
In nature, highly efficient and diverse consortia of microbes cycle carbon and other elements while generating energy for growth. Driving these reactions are organisms with the ability to extract electrons from the chemical substrates and transfer them ...
