Harmful algal blooms, caused by rapid growth and accumulation of certain microalgae in the ocean, pose considerable impacts on marine environments, aquatic industries and even public health. Here, we present the 7.2-megabase genome of the marine bacterium Hahella chejuensis including genes responsible for the biosynthesis of a pigment which has the lytic… (More)
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)
Cryobacterium arcticum PAMC 27867, a psychrotolerant, Gram-positive bacterium, was isolated from a sedimentary rock sample collected at Eureka Spurs in northern Victoria Land, Antarctica. Here, we report the genome sequence of C. arcticum PAMC 27867.
Psychrobacter alimentarius PAMC 27889, a Gram-negative, psychrophilic bacterium, was isolated from an Antarctic rock sample. Here, we report the complete genome of P. alimentarius PAMC 27889, which has the nonmevalonate methylerythritol phosphate pathway of terpenoid biosynthesis and a complete gene cluster for benzoate degradation.
An improved procedure for preparing PCR cloning vectors was developed. This procedure includes the incorporation of adapters to create XcmI restriction enzyme sites in pBluescript II SK(+) vectors, digestion with XcmI followed by further digestion of the small fragment produced by XcmI digestion with additional enzymes, and purification with PCR… (More)
