MethylobacillusRANK: GenusTAXONOMY: cellular organisms -> Bacteria -> Proteobacteria -> Betaproteobacteria -> Methylophilales -> Methylophilaceae -> Methylobacillus OVERVIEW: Rods 0.3–0.6 × 0.8–2.0 µm. Motile by means of a single polar flagellum or nonmotile. Gram negative. Most strains are obligate methylotrophs that grow on one-carbon compounds other than methane; however, some strains can also use fructose. Aerobic, having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor. The major cellular fatty acids are straight-chain saturated C16:0 and unsaturated C16:1. The major quinone is Q-8; Q-7 and Q-9 are minor components.The mol% G + C of the DNA is: 50–56.Type species: Methylobacillus glycogenes |
