methanoculleus methanoculleus methanoculleus is a genus of microbes within the family methanomicrobiaceae. the species of the genus methanoculleus live in marine environments brackish water, and are very common in bioreactors, landfills, and wastewater. unlike other archaea, methanoculleus and some species of related genera can use ethanol and some secondary alcohols as electron donors as they produce methane. this has implications as the production of methane as a greenhouse gas and consequences with respect to global climate change. methanoculleus methanoculleus bourgensis strain e02.3 scientific classification domain: archaea kingdom: euryarchaeota class: methanomicrobia order: methanomicrobiales family: methanomicrobiaceae genus: methanoculleusmaestrojun et al. 1990 type species methanoculleus bourgensiscorrig.
