This inhibits oxidation of CH4 since methanotrophic bacteria responsible for this process can not function in anoxic conditions normally found in waterlogged land. (skepticalscience.com)
Although M. frappieri JAM7 does not grow under anoxic conditions with NO 3 −, which concurs with the absence gene cluster encoding a dissimilatory NO 3 − reductase, the occurrence of nirK may be associated with the detoxification mechanism. (peerj.com)
This geographic distribution of anoxic conditions points towards the importance of paleogeography, basin restriction, and nutrient fluxes as key controls on the occurrence of extreme deoxygenation. (royalsociety.org)
