Distinct intestinal microbial communities of two sympatric anadromous Arctic salmonids and the effects of migration and feeding

Arctic Science, 2021
Although intestinal microbial communities from anadromous Arctic char (Salvelinus alpinus (Linnaeus, 1758)) in Kitikmeot, Nunavut, Canada, differ depending on the timing and location of capture, determinants of gut microbiota in other wild Arctic ...

Genome Analysis Reveals Diversity and Functional Potential of Novel Janthinobacterium Species From Subarctic Soils. [PDF]

Microbiologyopen
The Pseudomonadota are abundant and diverse members of high‐latitude soils. Here, we describe two novel species, Janthinobacterium silvisoli and Janthinobacterium saanense, of the order Burkholderiales, isolated from tundra heath and northern boreal forest soils.

Classification of a Violacein-Producing Psychrophilic Group of Isolates Associated with Freshwater in Antarctica and Description of Rugamonas violacea sp. nov.

Microbiology Spectrum, 2021
A group of 11 bacterial strains was isolated from streams and lakes located in a deglaciated northern part of James Ross Island, Antarctica. They were rod-shaped, Gram-stain-negative, motile, and catalase-positive and produced blue-violet-pigmented ...

Psychrophile C-Phycocyanin [PDF]

Plant Physiology, 1979
C-Phycocyanin was purified from an alga isolated in the Antarctic in 1968 and grown since that time in our laboratory at 4 C. Certain of its spectroscopic and immunochemical properties were studied, along with detailed examinations of its chemical composition and quaternary structure.

Comparative proteome analysis of psychrophilic versus mesophilic bacterial species: Insights into the molecular basis of cold adaptation of proteins

BMC Genomics, 2009
Background Cold adapted or psychrophilic organisms grow at low temperatures, where most of other organisms cannot grow. This adaptation requires a vast array of sequence, structural and physiological adjustments. To understand the molecular basis of cold
