Sporosarcina antarctica sp. nov., a psychrophilic bacterium isolated from the Antarctic [PDF]
INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 2008 A Gram-positive, psychrophilic, rod-shaped bacterium, designated strain N-05(T), was isolated from soil samples collected off King George Island, west Antarctica (6 degrees 13' 31'' S 5 degrees 57' 08'' W). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain N-05(T) was related to members of the genus Sporosarcina and had highest ...

Lewinella antarctica sp. nov., a marine bacterium isolated from Antarctic seawater [PDF]
INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 2009 A marine bacterium, designated IMCC3223T, was isolated from Antarctic coastal seawater and subjected to a polyphasic taxonomic investigation. Cells of the strain were Gram-negative, short to elongated rods that were orange-coloured but negative for flexirubin-type pigments, obligately aerobic, chemoheterotrophic and devoid of gliding or flagellar ...

All three subunits of RecBCD enzyme are essential for DNA repair and low-temperature growth in the Antarctic Pseudomonas syringae Lz4W. [PDF]
PLoS ONE, 2010 BACKGROUND: The recD mutants of the Antarctic Pseudomonas syringae Lz4W are sensitive to DNA-damaging agents and fail to grow at 4 degrees C. Generally, RecD associates with two other proteins (RecB and RecC) to produce RecBCD enzyme, which is involved ...

Evidence of late Quaternary environmental change in a continental east Antarctic lake from lacustrine sedimentary pigment distributions [PDF]
, 2005 A sediment core from Progress Lake, one of the oldest lacustrine sequences in East Antarctica, contains distinct zones dating from a previous interglacial (most likely Marine Isotope Stage 5e, c.

Energetic and Environmental Constraints on the Community Structure of Benthic Microbial Mats in Lake Fryxell, Antarctica. [PDF]
, 2020 Ecological communities are regulated by the flow of energy through environments. Energy flow is typically limited by access to photosynthetically active radiation (PAR) and oxygen concentration (O2).
