Antarctic permafrost soils have not received as much geocryological and biological study as has been devoted to the ice sheet, though the permafrost is more stable and older and inhabited by more… (More)
A gram-positive, motile, strict anaerobic spore-forming bacterium was isolated from the overcooled brine in the permafrost. The optimal temperature for isolate growth was 5–6°C at pH 6.8–7.2. The… (More)
Discovery of viable microorganisms in permafrost [1–4] raised the problem of their metabolic status. It is uncertain whether or not the microorganisms stored in permafrost sediments remain… (More)
Polysaccharide was revealed in the cytoplasm of spore-forming Clostridium algoriphilum 14D1 = VKM B-2271 = DSM 16153 grown on glucose at 5°C. This polymer was isolated, purified, and identified as a… (More)
A novel obligately anaerobic, non-spore-forming, rod-shaped, non-motile Gram-reaction-negative bacterium was isolated from infant faeces. The strain, designated NSB1(T), was able to grow on rich… (More)
A novel halotolerant psychrotrophic gram-negative bacterium, strain 2pS, was isolated from lenses of water brine in Arctic permafrost (cryopeg). The optimal growth of the new strain was observed at… (More)
Culture-based study of the faecal microbiome in two adult female subjects revealed the presence of two obligately anaerobic, non-spore-forming, rod-shaped, non-motile, Gram-negative bacterial strains… (More)
A novel constituent of bacterial polysaccharides, 2,3,4-triacetamido-2,3,4-trideoxy-L-arabinose, was found in the O-specific polysaccharide from the lipopolysaccharide of Psychrobacter cryohalolentis… (More)
