| pseudoalteromonas ruthenica sp. nov., isolated from marine invertebrates. | on the basis of phenotypic and genotypic characteristics and analysis of 165 rrna sequences, a novel species belonging to the genus pseudoalteromonas is described. two pale-orange-pigmented strains, kmm 300t and kmm 290, isolated respectively from a mussel, crenomytilus grayanus, and a scallop, patinopecten yessoensis, are marine, gram-negative, aerobic, rod-shaped bacteria that produce a number of antimicrobial compounds. the strains are able to degrade gelatin, elastin, starch, dna and tween 8 ... | 2002 | 11837308 |
| biofilm formation by pseudoalteromonas ruthenica and its removal by chlorine. | the distribution of a recently described marine bacterium, sbt 033 genbank accession no. ay723742), pseudoalteromonas ruthenica, at the seawater intake point, outfall and mixing point of an atomic power plant is described, and its ability to form biofilm was investigated. the effectiveness of the antifouling biocide chlorine in the inactivation of planktonic as well as biofilm cells of p. ruthenica was studied in the laboratory. the results show that the planktonic cells were more readily inacti ... | 2006 | 17178570 |
| preliminary characterization of exopolysaccharides produced by a marine biofilm-forming bacterium pseudoalteromonas ruthenica (sbt 033). | the major objective of the present study was the partial characterization of the exopolysaccharides (eps) produced by a marine biofilm-forming bacterium pseudoalteromonas ruthenica under shake culture conditions. | 2008 | 18086196 |
| the haloprotease cpi produced by the moderately halophilic bacterium pseudoalteromonas ruthenica is secreted by the type ii secretion pathway. | the gene (cpo) encoding the extracellular protease cpi produced by the moderately halophilic bacterium pseudoalteromonas ruthenica cp76 was cloned, and its nucleotide sequence was analyzed. the cpo gene encodes a 733-residue protein showing sequence similarity to metalloproteases of the m4 family. the type ii secretion apparatus was shown to be responsible for secretion of the haloprotease cpi. | 2009 | 19376897 |
| oil phytoremediation potential of hypersaline coasts of the arabian gulf using rhizosphere technology. | the rhizosphere and phyllosphere of the halophyte halonemum strobilaceum naturally inhabiting hypersaline coastal areas of the arabian gulf harbor up to 8.1 x 10(4)g(-1) and 3 x 10(2)g(-1), respectively, of extremely halophilic oil-utilizing microorganisms. such organisms were 14- to 38-fold more frequent in the rhizosphere than in the plant-free soil. frequent genera in the rhizosphere were affiliated to the archaea halobacterium sp. and halococcus sp., the firmicute brevibacillus borstenlensis ... | 2010 | 20303746 |
| bioactivity, chemical profiling, and 16s rrna-based phylogeny of pseudoalteromonas strains collected on a global research cruise. | one hundred one antibacterial pseudoalteromonas strains that inhibited growth of a vibrio anguillarum test strain were collected on a global research cruise (galathea 3), and 51 of the strains repeatedly demonstrated antibacterial activity. here, we profile secondary metabolites of these strains to determine if particular compounds serve as strain or species markers and to determine if the secondary metabolite profile of one strain represents the bioactivity of the entire species. 16s rrna gene ... | 2011 | 21305330 |
| culturable microbiota of ranched southern bluefin tuna (thunnus maccoyii castelnau). | the australian tuna industry is based on the ranching of wild southern bluefin tuna (sbt, thunnus maccoyii). within this industry, only opportunistic pathogens have been reported infecting external wounds of fish. this study aimed to identify different culturable bacteria present in three cohorts of sbt and to determine normal bacteria and potential pathogens in isolates from harvest fish and moribund/dead fish. post-mortem changes in the microbiota were also studied. | 2013 | 23789748 |
| draft genome sequence of the moderately halophilic bacterium pseudoalteromonas ruthenica strain cp76. | pseudoalteromonas ruthenica strain cp76, isolated from a saltern in spain, is a moderately halophilic bacterium belonging to the gammaproteobacteria. here we report the draft genome sequence, which consists of a 4.0-mb chromosome, of this strain, which is able to produce the extracellular enzyme haloprotease cpi. | 2013 | 23704184 |
