A wide diversity of microorganisms, typically growing as biofilms, has been implicated in
corrosion, a multi-trillion dollar a year problem. Aerobic microorganisms establish conditions …

Bioelectrocatalysis is an interdisciplinary research field combining biocatalysis and
electrocatalysis via the utilization of materials derived from biological systems as catalysts to …

Harvesting energy from the environment offers the promise of clean power for self-sustained
systems,. Known technologies—such as solar cells, thermoelectric devices and mechanical …

Extracellular electron transfer by Geobacter species through surface appendages known as
microbial nanowires is important in a range of globally important environmental phenomena …

OmcZ nanowires produced by Geobacter species have high electron conductivity (> 30 S
cm− 1). Of 111 cytochromes present in G. sulfurreducens, OmcZ is the only known nanowire …

Extracellular electron transfer (EET) is the physiological process that enables the reduction
or oxidation of molecules and minerals beyond the surface of a microbial cell. The first …

Electrically conductive appendages from the anaerobic bacterium Geobacter sulfurreducens
were first observed two decades ago, with genetic and biochemical data suggesting that …

Electroactive microorganisms (EAMs) are ubiquitous in nature and have attracted
considerable attention as they can be used for energy recovery and environmental …

Summary Long-range (> 10 μm) transport of electrons along networks of Geobacter
sulfurreducens protein filaments, known as microbial nanowires, has been invoked to …

Electrons can be transferred from microorganisms to multivalent metal ions that are
associated with minerals and vice versa. As the microbial cell envelope is neither physically …
