An iron hydrogenase was found in both ANME-1 metagenomes but not in any other methanotroph or methanogen [41] (Table 2).
The soil methanotroph community structure for five treatments (MF, RF, LOM, HOM and CK) were analysed to assess the effects of the different treatments on methanotroph abundance.

The previous research showed that N-deposition decreased C[H.sub.4] oxidation by 15.3% [40, 41], and the decreasing magnitude of C[H.sub.4] oxidation was much larger than that of C[O.sub.2] emission (15.3% for C[H.sub.4] and only 2.33% for C[O.sub.2]) owing to the fact that methanotroph might be more susceptible to the nitrogen deposition than other soil microbes relating to C[O.sub.2] emissions [42].
Rates of C[H.sub.4] oxidation are known to increase in relation to forest successional status as soil physical properties and methanotroph populations change (Tate et al.
Nutrient amendments in soil DNA stable isotope probing experiments reduce the observed methanotroph diversity.
In particular, the hps promoter, which in its native state drives the expression of 3-hexulose-6-phosphate synthase, was found to be useful for directing expression of heterolgous coding regions (e.g., crtZ) in the obligate methanotroph Methylomonas sp.
Polymerase chain reaction analysis revealed soluble methane monooxygenase genes in methanotrophic enrichments, and 16S rRNA analysis identified Methylocystis parvus with 98% similarity, further indicating the presence of a type II methanotroph. Dissimilatory sulfite reductase genes in sulfate-reducing enrichments prepared were also observed.

To single out how and which methanotrophs perform demethylation, the ORNL-led teamalong with methanotroph experts from the University of Michigan and Iowa State Universityinvestigated the behavior of many different methanotrophs and used sophisticated mass spectrometry to analyze methylmercury uptake and decomposition by these bacteria.
