Psychroflexus torquis gen. nov., sp. nov., a psychrophilic species from Antarctic sea ice, and reclassification of Flavobacterium gondwanense (Dobson et al. 1993) as Psychroflexus gondwanense gen. nov., comb. nov

Article Abstract:

A study was conducted to analyze a group of sea-ice-derived psychrophilic bacterial strains that can synthesize the polyunsaturated fatty acids. The strains were associated with the psychrotrophic, halophilic, planktonic species (Flavobacterium) gondwanense. Temperature and growth rate response curve analyses were determined in a temperature gradient incubator. Results showed that the sea ice strains and gondwanense were associated with a distinct group from other members of the Flavobacteriaceae family.

Diversity and association of psychrophilic bacteria in Antarctic sea ice

Article Abstract:

A study of the bacterial populations found in Antarctic sea ice by analyzing genes encoding the 16S rRNA is given. Results show that psychrophilic strains comprise most of the bacteria found in Antarctic sea ice. This discovery suggests that sea ice could be an important source of materials for biotechnology applications. Psychrophilic bacteria could be used in the production of lipids, pigments, drugs and enzymes.
