Draft Genome Sequences of Four Aerobic Isobutane-Metabolizing Bacteria
MICROBIOLOGY RESOURCE ANNOUNCEMENTS, 10(18).
Ed(s): J. Maresca

1983 journal article
Methane oxidation by Nitrosomonas europaea.
The Biochemical Journal.
MeSH headings : Ammonium Sulfate / metabolism; Kinetics; Methane / metabolism; Methanol / metabolism; Nitrosomonas / metabolism; Oxidation-Reduction; Oxidoreductases / metabolism; Oxygen Consumption
TL;DR:
It is concluded that methane is an alternative substrate for the NH3-oxidizing enzyme (ammonia mono-oxygenase), albeit with a much lower affinity than for methane mono- oxygengenase of methanotrophs.
