Membrane fatty acid analysis of Antarctic bacteria [PDF]
FEMS Microbiology Letters, 1993 Randomly selected strains of a bacterial collection of marine sea-ice bacteria from Antarctica were analyzed to obtain a profile of the membrane fatty acids. Results showed that short chain saturated and unsaturated fatty acids were more common in the psychrotrophs when compared to psychrophiles.

Resolving environmental drivers of microbial community structure in Antarctic soils [PDF]
, 2009 Antarctic soils are extremely cold, dry, and oligotrophic, yet harbour surprisingly high bacterial diversity. The severity of environmental conditions has constrained the development of multi-trophic communities, and species richness and distribution is ...

Proteorhodopsin-Bearing Bacteria in Antarctic Sea Ice [PDF]
Applied and Environmental Microbiology, 2010 ABSTRACT Proteorhodopsins (PRs) are widespread bacterial integral membrane proteins that function as light-driven proton pumps. Antarctic sea ice supports a complex community of autotrophic algae, heterotrophic bacteria, viruses, and protists that are an important food source for higher trophic levels in ice-covered regions of ...

Enzymatic Activity of Psychrotolerant Antarctic Bacteria [PDF]
Mikrobiolohichnyi Zhurnal, 2021 The Antarctic region has significant potential to study the biodiversity of microorganisms and to search for bacterial producers of glycolytic and proteolytic enzymes with new properties. The aim was to study the extracellular glycosidase and proteolytic activity of four bacteria strains isolated from black lichens of the cliffs of Galindez Island in ...

Gastrointestinal Bacteria of Certain Antarctic Birds and Mammals [PDF]
Applied Microbiology, 1970 An investigation was carried out of the aerobic gram-negative intestinal flora of 158 penguins, 30 skuas, and 66 seals from the Antarctic and sub-Antarctic zones and Phillip Island. Among penguins and seals, 17% and 11%, respectively, were devoid of aerobic enteric organisms, but microscopic examination showed the presence of other

Communication within East Antarctic Soil Bacteria [PDF]
Applied and Environmental Microbiology, 2019 Quorum sensing, a type of bacterial communication, is widely known to regulate many processes, including those that confer a survival advantage. However, little is known about communication by bacteria residing within Antarctic soils. Employing a combination of bacterial biosensors, analytical techniques, and genome mining, we found a variety of ...

Molecular adaptations in Antarctic fish and bacteria
Polar Science, 2010 Marine organisms, living in the cold waters of the Southern Ocean, are exposed to high oxygen concentrations. Cold-adapted organisms have developed networks of defence mechanisms to protect themselves against oxidative stress. The dominant suborder Notothenioidei of the Southern Ocean is one of the most interesting models, within vertebrates, to study ...
