These bacteria utilize methanol and hydrogen, but not methane. The major cellular fatty acid is straight-chain unsaturated C18:1 acid. The major ubiquinone is Q-10, and Q-9 and Q-11 are present as minor components. Based on the above data, these methylotrophs are distinguished from the other similar curved and ring-forming bacteria: Spirosoma linguale, Flectobacillus major, F. marinus, and Runella slithyformis. The latter three genera do not utilize methanol, have low deoxyribonucleic acid base compositions, possess different cellular fatty acids, and have a menaquinone-7 system. Furthermore, F. marinus is clearly distinguished from F. major in cellular fatty acid composition. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-36-3-415
