Methylotroph obligate

As an obligate methylotroph, the organism would not be able to grow in animals, where substrate would not be available.

Methanotrophs are obligate aerobes that use CH4 as a sole carbon and energy source (reviewed by R. S. Hanson and T. E. Hanson, 1996). They are a subset of the methylotrophic bacteria, all of which oxidize compounds lacking C-C bonds...
