Pigments from Antarctic bacteria and their biotechnological applications

Critical Reviews in Biotechnology, 2021
Pigments from microorganisms have triggered great interest in the market, mostly by their "natural" appeal, their favorable production conditions, in addition to the potential new chemical structures or naturally overproducing strains. They have been used in: food, feed, dairy, textile, pharmaceutical, and cosmetic industries.

Antarctic lichens as a source of phosphate-solubilizing bacteria

Extremophiles, 2021
In association with lichens, bacteria can play key roles in solubilizing sources of inorganic phosphates that are available in the environment. In this study, the potential of bacteria isolated from 15 Antarctic lichen samples for phosphate solubilization was investigated. From 124 bacteria tested, 66 (53%) were positive for phosphate solubilization in

The Bacteria in an Antarctic Peat

Journal of Applied Bacteriology, 1972
S ummary : Of a total of 119 strains of bacteria from 3 depths in an acid peat on Signy Island, S. Orkney, 52% belonged to the genus Brevibacterium. Twelve other genera were recorded of

Plasmids from antarctic bacteria

1999
In recent years a growing interest has been addressed to cold-adapted microorganisms, because of their biotechnological applications.1,2 The knowledge of the structural and functional features that justify the unusual activity of psychrophilic enzymes at low temperature represents the main goal of many comparative analyses;3–6 indeed, this information ...

Bacteria beneath the West Antarctic Ice Sheet

Environmental Microbiology, 2009
Summary Subglacial environments, particularly those that lie beneath polar ice sheets, are beginning to be recognized as an important part of Earth's biosphere. However, except for indirect indications of microbial assemblages in subglacial Lake Vostok, Antarctica, no sub‐ice sheet environments have been shown to ...

Searching for novel photolyases in UVC-resistant Antarctic bacteria

Extremophiles, 2017
Ultraviolet (UV) light irradiation has serious consequences for cell survival, including DNA damage by formation of cyclobutane pyrimidine dimers (CPD) and pyrimidine (6,4) pyrimidone photoproducts. In general, the Nucleotide Excision Repair pathway repairs these lesions; however, all living forms, except placental mammals and some marsupials, produce ...

Hydrocarbon degradation by Antarctic coastal bacteria

Antarctic Science, 1998
Bacterial cultures obtained through selective enrichment of beach sand collected 60 days and one year after treatment of sites in a pilot oil spill trial conducted at Airport Beach, Vestfold Hills, East Antarctica, were examined for the ability to degrade n-alkanes and phenanthrene. The effects of different hydrocarbon mixtures (Special Antarctic Blend

Maintenance of membrane fluidity in Antarctic bacteria

Polar Biology, 2001
Increase in the synthesis of membrane-fluidizing (such as unsaturated) fatty acids in cold-adapted bacteria is well documented. More recently, a polar carotenoid was found to rigidify synthetic membranes in an in vitro study. Enhanced biosynthesis of some fatty acids that increase membrane fluidity, and also of polar carotenoids has been evidenced in ...
