Methylococcus capsulatus is an obligately methanotrophic gram-negative, non-motile coccoid bacterium. M. capsulatus are thermotolerant; their cells are encapsulated and tend to have a diplococcoid shape. The cell wall is composed of three layers: outer membrane, peptidoglycan layer, and inner membrane. There are extensive intracytoplasmic membranes that are believed to be formed by invaginations of the inner cell membrane. More of these intracytoplasmic membranes are produced when M. capsulatus is grown at a high copper-to-biomass ratio. In addition to methane, M. capsulatus is able to oxidize some organic hydrogen-containing compounds such as methanol. It has been used commercially to produce animal feed from natural gas.[1][2][3][4]
