Microorganisms in polar areas may have important ecological roles in biogeochemical cycles and the food chain. They are adapted to polar environments by means of special physiological adaptation mechanisms that include cold-adapted enzymes and cryoprotectants such as exopolysaccharides. Culture collections for polar microorganisms can provide research(More)
The taxonomic relationship between Halomonas sinaiensis DSM 18067T and Halomonas caseinilytica JCM 14802T has not been established, despite the high similarity (99.6 %) of their 16S rRNA gene sequences. To clarify their taxonomic positions, a polyphasic approach was applied to both type strains. Genomic relatedness analyses between H. sinaiensis DSM 18067T(More)
A Gram-negative, strictly aerobic, non-motile, rod-shaped and psychrophilic bacterial strain, PAMC 27137T, was isolated from the marine sediment of the Ross Sea, Antarctica. Strain PAMC 27137T was observed to grow at 4–10 °C, at pH 6.5–7.5 and in the presence of 2.5–4.0 % (w/v) sea salts. Phylogenetic analysis based on the 16S rRNA gene sequence indicated(More)
The genus Lacinutrix, which belongs to the family Flavobacteriaceae, consists of seven bacterial species that were mainly isolated from marine life and sediments. As most bacteria in the family Flavobacteriaceae favor aerobic conditions, the seven bacterial species in the genus Lacinutrix also showed aerobic growth. We selected four monophyletic bacterial(More)
Following collection of seawater samples during an Arctic Chukchi Sea expedition cruise of the Korean icebreaker Araon in 2012, a total of 15,696 bacteria were randomly isolated from Marine Broth 2216 agar plates. Of these, 2,526 (16%) showed proteolytic activity and were identified as mainly Alteromonas (31%), Staphylococcus (27%), and Pseudoalteromonas(More)
Benthic bacterial communities in the ocean comprise the vast majority of prokaryotes on Earth and play crucial roles in the biogeochemical cycles and remineralization of organic matter. Despite the importance of the benthic bacterial communities in the ecosystem, no previous investigations of the bacterial community of sediments from the(More)
