Methanotrophs and Methylotrophs Methanotrophs utilize methane and/or a few other one-carbon compounds as sole source of carbon aerobes(Purple bacteria) widespread in nature in soil and water possess methane monooxygenase obligate Cl utilizers contain large amount of sterols in internal membrane Methylotrophs utilize methane and other one-carbon compounds as electron donors for energy generation and as sole sources of carbon many can utilize organic acids, ethanols and sugars
Methanotrophs and Methylotrophs Methanotrophs: utilize methane, and/or a few other one-carbon compounds as sole source of carbon aerobes (Purple Bacteria) widespread in nature in soil and water possess methane monooxygenase obligate C1 utilizers contain large amount of sterols in internal membrane Methylotrophs: utilize methane and other one-carbon compounds as electron donors for energy generation and as sole sources of carbon many can utilize organic acids, ethanols and sugars
Methanotrophs and Methylotrophs Classification Based on internal cell structure and carbon assimilation pathway Type I: ribulose monophosphate cycle, lack a complete TCa cycle Type II: Serin pathway Methylosinus, Type II Methylococcus capsulatus, Type I

Methanotrophic Symbionts of Animals Intact mussels as well as isolated mussel gill tissue consume methane at high rates in the presence of o2 due to symbiotic methanotrophic bacteria presence. Symbiotic methanotrophs in the gill tissue of a marine mussel living near hydrocarbon seeps in the Gulf of mexico
