Microbial communities of the Chinese marginal seas have rarely been reported. Here, bacterial and archaeal community structures and abundance in the surface sediment of four sea areas including the Bohai Sea (BS), North Yellow Sea (NYS), South Yellow Sea (SYS), and the north East China Sea (NECS) were surveyed by 16S ribosomal RNA (rRNA) gene pyrosequencing(More)
A Gram-stain-positive, strictly aerobic, rod-shaped, non-motile bacterium, designated strain XH274(T), was isolated from a deep sub-seafloor sediment sample collected from the South Pacific Gyre (41° 58' S 163° 11' W) during the Integrated Ocean Drilling Program (IODP) Expedition 329. Phylogenetic analysis based on 16S rRNA gene sequences indicated that(More)
Luteimonas abyssi XH031T, which was previously isolated from subseafloor environment of the South Pacific Gyre (SPG), was an aerobic, gram-negative bacterium, and was identified to be a novel species of the genus Luteimonas in the family of Xanthomonadaceae. The nutrients utilization and metabolic mechanisms of XH031T indicate its plasticity. In view of the(More)
Investigating the environmental influence on the community composition and abundance of denitrifiers in marine sediment ecosystem is essential for understanding of the ecosystem-level controls on the biogeochemical process of denitrification. In the present study, nirK-harboring denitrifying communities in different mud deposit zones of eastern China(More)
Bacterial communities are called another "organ" for aquatic animals and their important influence on the health of host has drawn increasing attention. Thus, it is important to study the relationships between aquatic animals and bacterial communities. Here, bacterial communities associated with Litopenaeus vannamei larvae at different healthy statuses(More)
A Gram-stain-negative, strictly aerobic, motile, non-gliding, oxidase-positive, catalase-positive, rod-shaped bacterium, designated strain YBW34T, was isolated from seawater from the bottom of the Yellow Sea at station H12 (-73m in depth). Growth occurred at 10-45 °C (optimum 28 °C), in the presence of 1-12 % NaCl (w/v, optimum 4 %) and at pH 6.0-8.0(More)
A Gram-stain-negative, strictly aerobic, non-flagellated, non-gliding, oxidase- and catalase-positive, rod-shaped and orange-pigmented bacterium with appendages, designated strain SW027T, was isolated from a surface seawater sample collected from the South Pacific Gyre (26° 29' S 137° 56' W) during the Integrated Ocean Drilling Program (IODP) Expedition(More)
