Methane-oxidizing bacteria

Ammonium N has been shown to be a competitive inhibitor of methane oxidation, suggesting that ammonia and ammonium are oxidized by the methane monooxygenase system. There are striking similarities between ammonium oxidation by Nitrosomonas and methane oxidation by methanotrophs. The methanotrophic bacteria are obligate aerobes and closely associated with the

Oremland et al. [136] subsequently demonstrated that methane-oxidizing bacteria also had the capacity to co-oxidize methyl bromide by methane monooxygenase produced during the oxidation of methane to methanol. They also showed that methanotrophic soils that had a high capacity to oxidize methane degraded14C-labeled methyl bromide to 14C02. 

The tank will reach steady-state conditions when the concentration of methane-oxidizing bacteria, [B], has increased to a constant cell density dictated by a balance of their ability to grow on methane against their losses due to wash out and die off ...

Methane-oxidizing bacteria, or methanotrophs, can play a central role in reducing CH4 emissions from estuaries, by converting CH4 into bacterial biomass or CO2 (Topp and Hanson, 1991). It has been estimated that methanotrophic bacteria in freshwater...

Within this setting, in shallow coastal water conditions, consortia of bacteria set up microbial mat columns to exploit the supply of sulphate and nitrate from water. In the muds below the mats, methanogens were active, and above them methane-oxidizing bacteria. The waters were enriched chemically by contributions from hydro-thermal water plumes, either from the laterally equivalent beginnings of Reliance Fm volcanism elsewhere in the basin, or from more distant oceanic sources. Photosynthetic green sulphur bacteria may have oxidized H2S to S°, whereas sulphate and sulphur reducers operated in the reverse direction. 

Once released to surface water, 1,1,1-trichloroethane is expected to undergo volatilization to the atmosphere. Neither adsorption to sediment nor bioconcentration in aquatic organisms is recognized as an important removal process. Aerobic biodegradation of 1,1,1-trichloroethane can occur in the presence of methane-oxidizing bacteria. If released to groundwater, biodegradation of...
