Methylocystaceae Bowman 2006
General information
Description and emendation
Cells are pyriform, vibrioid, reniform, or rod-like in shape, sometimes arranged in rosettes. Reproduce by budding or binary division. Produce heat- and desiccation-resistant exospores or lipoidal cysts. Motility varies; if present, cells are propelled by a polar and/or subpolar flagellar tuft. Cells contain type II intra-cytoplasmic membranes, which are arranged as layers in parallel to the periphery of the cell wall. Possess an aerobic, strictly respiratory metabolism. Obligately methanotrophic, utilizing only methane and methanol as sole carbon and energy sources. C2+ and other C1 compounds are not utilized. Fix formaldehyde for cell carbon via the serine pathway. Enzymes for the Benson-Calvin cycle pathway are absent. The tricarboxylic acid pathway is complete. Fix atmospheric nitrogen by means of an oxygen-sensitive nitrogenase. Mesophilic. Nonhalophilic. Major habitats include soils, freshwater sediments, and groundwater. Primary fatty acids are C18:1 ω8c and C18:1 ω7c. Primary quinone is ubiquinone-8 (Q-8). The mol% G+C of the DNA is: 61-67 (Tm).
