Background Methanoculleus marisnigri (strain ATCC 35101 / DSM 1498 / JR1) is an anaerobic methanogenic archaeon phylogenetically associated with the order Methanomicrobiales. Methanoculleus marisnigri was first isolated from sediment from the Black Sea, but has also been identified in freshwater sediments. Members of the genus Methanoculleus are found commonly in marine and brackish environments, and they are among the most prevalent methanogens found in wastewater and sewage bioreactors and in landfills. Methanoculleus marisnigri can use hydrogen, formate, and secondary alcohols, such as propanol and butanol, for methanogenesis. A metabolic feature of Methanoculleus species and some closely related genera, but unique among the methanogens, is the ability to use ethanol and a variety of secondary alcohols as electron donors for methanogenesis, and this may contribute to their dominance in biomethanation processes.
