Evaluation of methyl fluoride and dimethyl ether as inhibitors of aerobic methane oxidation
Article Abstract:
The effects of methyl fluoride (MF) and dimethyl ether (DME) on the methane oxidation activity in natural soil samples were investigated. The results showed that MF and DME did not affect the oxidation of methanol and formate, although they could block the oxidation of methane. Further characterization showed that MF is a more effective inhibitor of methane oxidation than DME. In addition, MF could inhibit the cooxidation of ethane and propane in mathane-oxidizing soils. However, both MF and DME could inhibit ammonia oxidation or nitrification.

Rapid consumption of low concentrations of methyl bromide by soil bacteria
Article Abstract:
A study was conducted to determine roles of soil bacteria in the uptake of methyl bromide in soils. A dilution system that can produce mixing ratios of methyl bromide and an analytical method were utilized. Results revealed that the varied soil moisture and temperature optima from different soils were caused by the diverse consumption activity of soil bacteria. However, soil fungi were not involved in the removal of methyl bromide from the soil.

Consumption of tropospheric levels of methyl bromide by C(sub 1) compound-utilizing bacteria and comparison to saturation kinetics
Article Abstract:
Methylotrophs and methanotrophs such as strain IMB-1 and Leisingeria methylohalidivorans strain MB2(super T) can oxidize methyl bromide at tropospheric concentrations of 12 parts per trillion by volume. Methyl bromide is a fumigant that contributes to ozone depletion.
