Bacterial oxidation of dibromomethane and methyl bromide in natural waters and enrichment cultures

Article Abstract:

A study was conducted to analyze the bacterial oxidation of dibromomethane and methyl bromide from different aquatic environments and to determine whether bacteria supports a role in brominated methane oxidation in natural waters using methyl fluoride as an inhibitor. Results suggested that bacteria oxidize brominated methanes in nature and supported themselves on other types of C1 compounds. Findings also showed that volatilization may support the removal of brominated methanes from water columns.

Strain IMB-1, a novel bacterium for the removal of methyl bromide in fumigated agricultural soils

Article Abstract:

Research was conducted to examine strain IMB-1, a facultatively methylotrophic bacterium, for the removal of methyl bromide in fumigated agricultural soils. The addition of cell suspensions of strain IMB-1 to soils greatly accelerates the oxidation of MeBr as does pretreatment of soils with low concentrations of methyl iodide. Results indicate that soil treatment strategies can be developed where MeBr could be effectively consumed by bacteria during field fumigations.

Methane and trichloroethylene oxidation by an estuarine methanotroph, Methylobacter sp. strain BB5.1

Article Abstract:

Single-colony isolation techniques are performed on methane-dependent bacteria from sediment enrichments from the Newport Beach Estuary, CA, to isolate strains that efficiently oxidize methane and trichloroethylene. The BB5.1 strain was selected for further characterization. This strain is a motile, rod-shaped bacterium able to oxidize trichloroethylene in the presence of copper. Methane oxidation is also faster in the presence of copper.
