We observed dimethyl sulfide and methanthiol production in pure incubations of the methanogen Methanosarcina acetivorans when carbon monoxide (CO) served as the only electron donor. Energy conservation likely uses sodium ion gradients for ATP synthesis. This novel metabolism permits utilization of CO by the methanogen, resulting in quantitative sulfide methylation.
