A novel Gram stain-negative, catalase- and oxidase-positive, strictly aerobic bacterium, designated strain H50T, was isolated from an amphioxus breeding zone in the coastal region of the Yellow Sea, China. Cells were observed to be ovoid or short rods, lacked flagella and were found to contain bacteriochlorophyll a. Poly-beta-hydroxybutyrate was found to be(More)
Gram-negative bacteria use N-acyl homoserine lactones (AHLs) as quorum sensing (QS) signaling molecules for interspecies communication, and AHL-dependent QS is related with virulence factor production in many bacterial pathogens. Quorum quenching, the enzymatic degradation of the signaling molecule, would attenuate virulence rather than kill the pathogens,(More)
Pseudoalteromonas flavipulchra JG1 produces a protein PfaP and a range of small-molecule compounds with inhibitory activities against Vibrio anguillarum. The PfaP protein was purified from the extracellular products of JG1 by electroelution, and antibacterial activity was observed by an in-gel antibacterial assay. The complete amino acid sequence (694 aa)(More)
A novel Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic strain with gliding motility, designated XH134(T), was isolated from surface seawater of the South Pacific Gyre (45° 58' S 163° 11' W) during the Integrated Ocean Drilling Program Expedition 329. The major respiratory quinone of strain XH134(T) was MK-6. The dominant fatty acids of(More)
A novel Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic strain with gliding motility, designated SW024(T), was isolated from surface seawater of the South Pacific Gyre (26° 29' S 137° 56' W) during the Integrated Ocean Drilling Program Expedition 329. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain was(More)
A Gram-negative, strictly aerobic, motile, short rod-shaped bacterium with peritrichous flagella, designated JYr12T, was isolated from sediment of an amphioxus breeding zone in the coastal region of Qingdao, China. Strain JYr12T was found to grow optimally at 28 °C, at pH 7.0 and in the presence of 2–3 % (w/v) NaCl. The organism was determined to contain(More)
A Gram-stain-negative, strictly aerobic, yellow-pigmented, rod-shaped and N-acylhomoserine lactone-degrading bacterium, designated strain Th78(T), was isolated from the intestine of a cultured flounder (Paralichthys olivaceus). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain Th78(T) belonged to the genus Flaviramulus (family(More)
A Gram-stain-negative, strictly aerobic, non-motile, cream, long rod-shaped bacterium, designated strain ZL136(T), was isolated from deep water of the South China Sea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain belonged to the genus Roseivivax with highest sequence similarity to Roseivivax halodurans OCh 239(T)(More)
A Gram-stain-negative, strictly aerobic, non-motile, rod-shaped, manganese-oxidizing bacterial strain, designated DY6-4T, was isolated from the surface sediment of the Pacific Clarion-Clipperton Fracture Zone. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain DY6-4T formed a lineage within the family Rhodobacteraceae and was(More)
Genome sequencing of Catenovulum agarivorans YM01T reveals 15 open-reading frames (ORFs) encoding various agarases. In this study, extracellular proteins of YM01T were precipitated by ammonium sulfate and separated by one-dimensional gel electrophoresis. The results of in-gel agarase activity assay and mass spectrometry analysis revealed that the protein,(More)
