Microbe Profile: Geobacter metallireducens: a model for novel physiologies of biogeochemical and technological significance

Microbiology (Reading). 2022 Feb;168(2). doi: 10.1099/mic.0.001138.


Geobacter metallireducens has served as the initial model for a substantial number of newly recognized microbial physiologies that play an important role in biogeochemical cycling of carbon, metals and nutrients. The strategies used by G. metallireducens for microbial interaction with minerals, contaminants, other microbes and electrodes have led to new technologies for bioremediation, bioenergy conversion and the sustainable production of 'green' electronics.

Keywords: Fe(III) reduction; Geobacter; corrosion; direct interspecies electron transfer; electromicrobiology.
