Structural adaptations of the cold-active citrate synthase from an Antarctic bacterium [PDF]
Structure, 1998 The structural basis of adaptation of enzymes to low temperature is poorly understood. Dimeric citrate synthase has been used as a model enzyme to study the structural basis of thermostability, the structure of the enzyme from organisms living in habitats at 55 degrees C and 100 degrees C having previously been determined. Here the study is extended to

Molybdate reduction to molybdenum blue by an Antarctic bacterium. [PDF]
Biomed Res Int, 2013 A molybdenum-reducing bacterium from Antarctica has been isolated. The bacterium converts sodium molybdate or Mo6+to molybdenum blue (Mo-blue). Electron donors such as glucose, sucrose, fructose, and lactose supported molybdate reduction. Ammonium sulphate was the best nitrogen source for molybdate reduction.

Conditional gene silencing in the Antarctic bacterium Pseudoalteromonas haloplanktis TAC125
Research in Microbiology, 2022 Since the release in 2005 of the genome sequence and annotation of the first Antarctic marine bacterium, the number of genomes of psychrophilic microorganisms in public databases has steadily increased. Unfortunately, the lack of effective molecular tools for the manipulation of these environmental strains still hampers our understanding of their ...

Optimization of phenol degradation by Antarctic bacteriumRhodococcussp. [PDF]
Antarctic Science, 2020 AbstractThis study focused on the ability of the Antarctic bacteriumRhodococcussp. strain AQ5-14 to survive exposure to and to degrade high concentrations of phenol at 0.5 g l-1. After initial evaluation of phenol-degrading performance, the effects of salinity, pH and temperature on the rate of phenol degradation were examined.

Novel essential role of ethanol oxidation genes at low temperature revealed by transcriptome analysis in the antarctic bacterium pseudomonas extremaustralis [PDF]
, 2015 Temperature is one of the most important factors for bacterial growth and development. Cold environments are widely distributed on earth, and psychrotolerant and psychrophilic microorganisms have developed different adaptation strategies to cope with the

Pseudomonas deceptionensis sp. nov., a psychrotolerant bacterium from the Antarctic [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2011 During the taxonomic investigation of cold-adapted bacteria from samples collected in the Antarctic area of the South Shetland Islands, one Gram-reaction-negative, psychrotolerant, aerobic bacterium, designated strain M1T, was isolated from marine sediment collected on Deception Island.

Bacillus macquariensis n.sp., a Psychrotrophic Bacterium from Sub-Antarctic Soil [PDF]
Journal of General Microbiology, 1966 Summary: A new species of the genus Bacillus was isolated from Macquarie Island soil. The organism is psychrotrophic, producing spores at temperatures down to and including 0°. The maximum temperature for growth is 25°. Apart from its temperature relations, it most closely resembles B.

Carotenoid Cocktail Produced by An Antarctic Soil Flavobacterium with Biotechnological Potential
Microorganisms, 2021 Carotenoids are highly important in pigmentation, and its content in farmed crustaceans and fish correlates to their market value. These pigments also have a nutritional role in aquaculture where they are routinely added as a marine animal food ...
