On the rocks: the microbiology of Antarctic Dry Valley soils
- S. C. Cary, I. McDonald, J. Barrett, D. Cowan
- Biology, Medicine
- Nature Reviews Microbiology
- 1 February 2010
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
- Soeren Warneke, L. Schipper, Denise A Bruesewitz, I. McDonald, S. Cameron
- Chemistry
- 1 March 2011
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 with… Expand
Nitrate removal, communities of denitrifiers and adverse effects in different carbon substrates for use in denitrification beds.
- Soeren Warneke, L. Schipper, +4 authors I. McDonald
- Chemistry, Medicine
- Water research
- 1 November 2011
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 into… Expand
Molecular Ecology Techniques for the Study of Aerobic Methanotrophs
- I. McDonald, L. Bodrossy, Y. Chen, J. Murrell
- Biology, Medicine
- Applied and Environmental Microbiology
- 28 December 2007
Methane oxidation can occur in both aerobic and anaerobic environments; however, these are completely different processes involving different groups of prokaryotes. Aerobic methane oxidation is… Expand
Stable-isotope probing of nucleic acids: a window to the function of uncultured microorganisms.
- S. Radajewski, I. McDonald, J. Murrell
- Biology, Medicine
- Current opinion in biotechnology
- 1 June 2003
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 the… Expand
Characterization of Methanotrophic Bacterial Populations in Soils Showing Atmospheric Methane Uptake
- A. Holmes, P. Roslev, I. McDonald, N. Iversen, K. Henriksen, J. Murrell
- Biology, Medicine
- Applied and Environmental Microbiology
- 1 August 1999
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 these… Expand
The Inter-Valley Soil Comparative Survey: the ecology of Dry Valley edaphic microbial communities
- C. Lee, B. Barbier, E. M. Bottos, I. McDonald, S. C. Cary
- Biology, Medicine
- The ISME Journal
- 1 May 2012
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 limited… Expand
Leisingera methylohalidivorans gen. nov., sp. nov., a marine methylotroph that grows on methyl bromide.
- J. Schaefer, K. Goodwin, I. McDonald, J. Murrell, R. Oremland
- Biology, Medicine
- International journal of systematic and…
- 1 May 2002
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, as… Expand
Analysis of methanotrophic bacteria in Movile Cave by stable isotope probing.
- E. Hutchens, S. Radajewski, M. Dumont, I. McDonald, J. Murrell
- Biology, Medicine
- Environmental microbiology
- 4 December 2003
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 are… Expand
Stable-isotope probing implicates Methylophaga spp and novel Gammaproteobacteria in marine methanol and methylamine metabolism
- J. Neufeld, H. Schäfer, M. J. Cox, R. Boden, I. McDonald, J. Murrell
- Biology, Medicine
- The ISME Journal
- 9 August 2007
The metabolism of one-carbon (C1) compounds in the marine environment affects global warming, seawater ecology and atmospheric chemistry. Despite their global significance, marine microorganisms that… Expand
