The Methylococcaceae are a family of bacteria that obtain their carbon and energy from methane, called methanotrophs.〔.〕 They comprise the type I methanotrophs, in contrast to the Methylocystaceae or type II methanotrophs. They belong among the gamma subdivision of the Proteobacteria, and are typically given their own order. The Methylococcaceae have internal membranes in the form of flattened discs, perpendicular to the cell wall.〔 Methane is oxidized to give formaldehyde, which is fixed by a process called the RuMP cycle (Ribulose Monophosphate Cycle). Here formaldehyde is combined with sugar ribulose, producing hexulose. This, in turn, is broken down to produce glyceraldehyde, which is used to produce new ribulose and other organic compounds.〔 Catabolism does not involve a complete citric acid cycle.〔George M. Garrity: ''Bergey's Manual of Systematic Bacteriology''. 2. Auflage. Springer, New York, 2005, Volume 2: ''The Proteobacteria, Part B: The Gammaproteobacteria''〕 Some species of the Methylococcaceae have formed with certain marine mussels endosymbiotic relationships.〔 ==References==
