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 ...

Structure and application of antifreeze proteins from Antarctic bacteria. [PDF]
Microb Cell Fact, 2017 Antifreeze proteins (AFPs) production is a survival strategy of psychrophiles in ice. These proteins have potential in frozen food industry avoiding the damage in the structure of animal or vegetal foods. Moreover, there is not much information regarding the interaction of Antarctic bacterial AFPs with ice, and new determinations are needed to ...

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 ...

Frontiers in Microbiology, 2021 Alginate, mainly derived from brown algae, is an important carbon source that can support the growth of marine microorganisms in the Arctic and Antarctic regions. However, there is a lack of systematic investigation and comparison of alginate utilization

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.

Data, 2021 Marine bacteria, which are known as key drivers for marine biogeochemical cycles and Earth’s climate system, are mainly responsible for the decomposition of organic matter and production of climate-relevant gases (i.e., CO₂, N₂O, and CH₄).

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 ...
