On the rocks: the microbiology of Antarctic Dry Valley soils
The arid soils of the Antarctic Dry Valleys constitute some of the oldest, coldest, driest and most oligotrophic soils on Earth. Early studies suggested that the Dry Valley soils contained, at best,Expand

Rates, controls and potential adverse effects of nitrate removal in a denitrification bed
Abstract Denitrification beds are a simple approach for removing nitrate (NO3−) from a range of point sources prior to discharge into receiving waters. These beds are large containers filled withExpand

Nitrate removal, communities of denitrifiers and adverse effects in different carbon substrates for use in denitrification beds.
Denitrification beds are containers filled with wood by-products that serve as a carbon and energy source to denitrifiers, which reduce nitrate (NO(3)(-)) from point source discharges intoExpand

Molecular Ecology Techniques for the Study of Aerobic Methanotrophs
Methane oxidation can occur in both aerobic and anaerobic environments; however, these are completely different processes involving different groups of prokaryotes. Aerobic methane oxidation isExpand

Stable-isotope probing of nucleic acids: a window to the function of uncultured microorganisms.
Phylogeny based on ribosomal RNA sequences alone is rarely a reliable indicator of microbial function. To circumvent this problem, nucleic acid based techniques have been developed that exploit theExpand

Characterization of Methanotrophic Bacterial Populations in Soils Showing Atmospheric Methane Uptake
ABSTRACT The global methane cycle includes both terrestrial and atmospheric processes and may contribute to feedback regulation of the climate. Most oxic soils are a net sink for methane, and theseExpand

The Inter-Valley Soil Comparative Survey: the ecology of Dry Valley edaphic microbial communities
Recent applications of molecular genetics to edaphic microbial communities of the McMurdo Dry Valleys and elsewhere have rejected a long-held belief that Antarctic soils contain extremely limitedExpand

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

Microbial community composition in soils of Northern Victoria Land, Antarctica.
Biotic communities and ecosystem dynamics in terrestrial Antarctica are limited by an array of extreme conditions including low temperatures, moisture and organic matter availability, high salinity,Expand

Analysis of methanotrophic bacteria in Movile Cave by stable isotope probing.
Movile Cave is an unusual groundwater ecosystem that is supported by in situ chemoautotrophic production. The cave atmosphere contains 1-2% methane (CH4), although much higher concentrations areExpand
