Figure 4. Metabolism of DMNA by Methylosinus trichosporium OB3b (MT OBSb) in the presence of different concentrations of DMNA. Average rates at 0-24 h of incubation are given [76]. The rates of cellular uptake, COj production, and methane metabolism are represented by Vp ( ), VcOj ( ) and VcH (O), respectively.

Particulate MMO. Methanotrophic bacteria utilize methane as a carbon source for growth. Oxidation of CH4 to methanol is the first step in the methane metabolism, and this step is catalyzed by methane monooxygenase (MMO). 

It is less conunonly known that methane was one of the original atmospheric gases and is a normal product of the microbial decomposition of organic matter under anaerobic conditions. Bacteria involved in production of methane are unique in their metabolism and other properties. The balanced...

Enzymes necessary for the metabolism of a substrate may be induced by growth on structurally unrelated compounds. In the examples used for illustration, monooxygenases play a cardinal role as a result of the versatility of methane monooxygenase, while monooxygenases that may be involved in toluene degradation are discussed in Chapter 3, Part 1 and Chapter 8, Part 1.

There has been considerable interest in the anaerobic metabolism of methane in the large reservoirs that lie beneath the seafloor, since little of this reaches the oxic conditions in the water column. Consortia of archaea that have so far resisted isolation and sulfate-reducing bacteria have been implicated (Orphan et al. 2002) ...
