Life In The Absence Of Oxygen: Alternative Electron Acceptors For Anaerobic Microorganisms In A Petroleum Environment, Meli̇ke Balk

Turkish Journal of Biology

Anaerobic microorganisms derive energy by transferring electrons from an external source or donor to an external electron sink or terminal acceptor and often have the capacity to reduce 2 or more terminal electron acceptors. The well-known type of microbial respiration, in which oxygen serves as an electron acceptor for the oxidation of organic carbon and/or hydrogen, has been studied elsewhere in detail. Anaerobic microorganisms are widely distributed in oil-producing vents, hydrothermal vents, volcanic hot springs, non-volcanic geothermally heated subsurface aquifers, and soil. In this study, anaerobic, thermophilic, and fermenting microorganisms in a petroleum sample from the Adıyaman region of Turkey …
