Geobacter sulfurreducens can grow with oxygen as a terminal electron acceptor

Appl Environ Microbiol. 2004 Apr;70(4):2525-8. doi: 10.1128/AEM.70.4.2525-2528.2004.


Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor at concentrations of 10% or less in the headspace. These results help explain how Geobacter species may survive in oxic subsurface environments, being poised to rapidly take advantage of the development of anoxic conditions.
