Leisingera methylohalidivorans gen. nov., sp. nov., a marine methylotroph that grows on methyl bromide.
A marine methylotroph, designated strain MB2T, was isolated for its ability to grow on methyl bromide as a sole carbon and energy source. Methyl chloride and methyl iodide also supported growth, asExpand

High methylation rates of mercury bound to cysteine by Geobacter sulfurreducens
Methylmercury bioaccumulates in aquatic food chains and can cross the blood–brain barrier, making this organometallic compound a much more worrisome pollutant than inorganic mercury. ExperimentalExpand

Bacterial dissimilatory reduction of arsenate and sulfate in meromictic Mono Lake, California
Abstract The stratified (meromictic) water column of alkaline and hypersaline Mono Lake, California, contains high concentrations of dissolved inorganic arsenic (∼200 μmol/L). Arsenic speciationExpand

Role of the bacterial organomercury lyase (MerB) in controlling methylmercury accumulation in mercury-contaminated natural waters.
The curious phenomenon of similar levels of methylmercury (MeHg) accumulation in fish from contaminated and pristine environments may be explained by the observation that the proportion of totalExpand

Active transport, substrate specificity, and methylation of Hg(II) in anaerobic bacteria
The formation of methylmercury (MeHg), which is biomagnified in aquatic food chains and poses a risk to human health, is effected by some iron- and sulfate-reducing bacteria (FeRB and SRB) inExpand

Detection of a key Hg methylation gene, hgcA, in wetland soils.
The corrinoid protein, HgcA has been shown to be essential for Hg methylation in anaerobic bacteria. We investigated the diversity of hgcA from temperate and tropical wetland soils where HgExpand

mer -Mediated Resistance and Volatilization of Hg(II) Under Anaerobic Conditions
The response of the mercury-resistant denitrifier, Pseudomonas stutzeri strain OX, and its sensitive derivative OX1 to HgCl 2 was examined under aerobic and anaerobic conditions to evaluate theExpand

Bacterial Oxidation of Dibromomethane and Methyl Bromide in Natural Waters and Enrichment Cultures
ABSTRACT Bacterial oxidation of14CH2Br2 and14CH3Br was measured in freshwater, estuarine, seawater, and hypersaline-alkaline samples. In general, bacteria from the various sites oxidized similarExpand

Oxidation of Methyl Halides by the Facultative Methylotroph Strain IMB-1
ABSTRACT Washed cell suspensions of the facultative methylotroph strain IMB-1 grown on methyl bromide (MeBr) were able to consume methyl chloride (MeCl) and methyl iodide (MeI) as well as MeBr.Expand

Analysis of mercuric reductase (merA) gene diversity in an anaerobic mercury-contaminated sediment enrichment.
The reduction of ionic mercury to elemental mercury by the mercuric reductase (MerA) enzyme plays an important role in the biogeochemical cycling of mercury in contaminated environments byExpand
