Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica. [PDF]
The Earth's crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth's surface.

Development of an improved Pseudoalteromonas haloplanktis TAC125 strain for recombinant protein secretion at low temperature [PDF]
Background: In a previous paper, we reported the accomplishment of a cold gene-expression system for the recombinant secretion of heterologous proteins in Pseudoalteromonas haloplanktis TAC125.

Fatty acid adaptation in an Antarctic bacterium - changes in primer utilization [PDF]
The fatty acid composition and temperature/growth characteristics of a psychrophilic bacterium, strain ACAM 456, isolated from Antarctic sea-ice is reported. The bacterium produced acyl components that may be grouped in three different carbon chain types: even-chain, odd-chain and iso-branched odd-chain.

Airborne bacterial populations above desert soils of the McMurdo Dry Valleys, Antarctica [PDF]
Bacteria are assumed to disperse widely via aerosolized transport due to their small size and resilience. The question of microbial endemicity in isolated populations is directly related to the level of airborne exogenous inputs, yet this has proven hard

Seasonal changes in microbial dissolved organic sulfur transformations in coastal waters [PDF]
The marine trace gas dimethylsulfide (DMS) is the single most important biogenic source of atmospheric sulfur, accounting for up to 80% of global biogenic sulfur emissions.

A novel pathway producing dimethylsulphide in bacteria is widespread in soil environments [PDF]
The volatile compound dimethylsulphide (DMS) is important in climate regulation, the sulphur cycle and signalling to higher organisms. Microbial catabolism of the marine osmolyte dimethylsulphoniopropionate (DMSP) is thought to be the major biological ...

Preliminary Analysis of Life within a Former Subglacial Lake Sediment in Antarctica
Since the first descriptions of Antarctic subglacial lakes, there has been a growing interest and awareness of the possibility that life will exist and potentially thrive in these unique and little known environments. The unusual combination of selection
