Nitrate-driven anaerobic ethane oxidation by bacterial cultures (PRJCA020246)
Ethane, the second most abundant hydrocarbon gas in vast anoxic environments, could be effectively oxidized with sulfate as electron acceptor. Although nitrate is a more thermodynamically feasible electron acceptor for anaerobic ethane oxidation than sulfate, little is known about the mechanism of nitrate-driven anaerobic ethane oxidation. Here, denitrifying anaerobic ethane oxidation culture was enriched through long-term operation of bioreacotr fed with nitrate and ethane.
