phylogenetic analysis of the genera alteromonas, shewanella, and moritella using genes coding for small-subunit rrna sequences and division of the genus alteromonas into two genera, alteromonas (emended) and pseudoalteromonas gen. nov., and proposal of twelve new species combinations.small-subunit ribosomal dna sequences were determined for 17 strains belonging to the genera alteromonas, shewanella, vibrio, and pseudomonas, and these sequences were analyzed by phylogenetic methods. the resulting data confirmed the existence of the genera shewanella and moritella, but suggested that the genus alteromonas should be split into two genera. we propose that a new genus, the genus pseudoalteromonas, should be created to accommodate 11 species that were previously alteromonas specie ...19957547295
assignment of alteromonas elyakovii kmm 162t and five strains isolated from spot-wounded fronds of laminaria japonica to pseudoalteromonas elyakovii comb. nov. and the extended description of the species.a marine bacterium, alteromonas elyakovii kmm 162t, which was described recently, and five strains isolated from spot-wounded fronds of laminaria japonica have been subjected to phylogenetic analysis, and geno- and phenotypic characterization. the phenotypic features of pseudoalteromonas elyakovii strains were closely related to that of pseudoalteromonas espejiana iam 12640t, but utilization of three carbon compounds (d-mannose, l-tyrosine and trehalose) distinguished both species. the g+c conte ...200010826813
[degradation of fucoidan by the marine proteobacterium pseudoalteromonas citrea].it was found that pseudoalteromonas citrea strains kmm 3296 and kmm 3298 isolated from the brown algae fucus evanescens and chorda filum, respectively, and strain 3297 isolated from the sea cucumber apostichopus japonicus are able to degrade fucoidans. the fucoidanases of these strains efficiently degraded the fucoidan of brown algae at ph 6.5-7.0 and remained active at 40-50 degrees c. the endo-type hydrolysis of fucoidan resulted in the formation of sulfated alpha-l-fucooligosaccharides. the o ...200211910806
tolerance to cadmium of free-living and associated with marine animals and eelgrass marine gamma-proteobacteria.the tolerance to cd2+ and possible mechanisms of cd2+ detoxification by 178 free-living bacteria isolated from sea water, associated with marine animals (a mussel crenomytilus grayanus, a scallop patinopecten yessoensis), and eelgrass zostera marina collected in the sea of japan and the sea of okhotsk have been studied. the concentrations of 25 and 50 mg cd2+/l were highly toxic and inhibited the growth from 54% to 78% of the total bacteria studied. the free-living bacteria isolated from seawate ...200211927987
[characterization of marine bacteria pseudoalteromonas citrea degradating fucoidan].two strains kmm 3296 and kmm 3298, isolated from the surface of brown algae chorda filum and fucus evanescens thalli and strain kmm 3297, isolated from celomic fluid of holoturian apostichopus japonicus, were identified as pseudoalteromonas citrea on the basis of pheno-, geno- and phylotypic features. the studied bacteria were different from other bacteria of the species as to their ability to destruct sulphated polysaccharides of brown algae, fucoidans.200212190022
[antibiotic properties of the pseudoalteromonas genus bacteria isolated from the black sea water and molluscs].antagonistic properties of 41 strains of alteromonas-like bacteria isolated from the black sea water and molluscs have been studied. being grown on the rich medium "b" for marine bacteria, 21% of strains have shown high antagonistic activity against phytopathogenic fungi; 6% of strains inhibited the growth of bacillus subtilis, proteus vulgaris and candida albicans. spectrum of antagonistic activity was essentially changed on synthetic "bm" medium with acetate, glutamate, alpha-alanine as a sing ...200212190034
characterization of pseudoalteromonas citrea and p. nigrifaciens isolated from different ecological habitats based on rep-pcr genomic fingerprints.dna primers corresponding to conserved repetitive interspersed genomic motifs and pcr were used to show that rep, eric and box-like dna sequences are present in marine, oxidative, gram-negative pseudoalteromonas strains. rep, eric and box-pcr were used for rapid molecular characterization of both the type species of the genus and environmental strains isolated from samples collected in different geographical areas. pcr-generated genomic fingerprint patterns were found to be both complex and stra ...200212353883
[taxonomical study of bacteria from genera alteromonas and pseudoalteromonas isolated from black sea water and invertebrates].nineteen (19) strains of bacteria have been isolated from the black sea water and invertebrates (mollusks and actinia). most of them have been identified as alteromonas macleodii, pseudoalteromonas citrea and p. haloplanktis on the basis of polyphasic taxonomical analysis. six strains showed 96-97 % similarity to 16s rrna sequence of the known species of pseudoalteromonas and obviously belonged to new species. the studied strains have been characterized by a wide spectrum of phenotypic features ...200516250230
[characteristics of adhesion of epiphytic bacteria on leaves of the seagrass zostera marina and on abiotic surfaces].a comparative study of the adhesion of epiphytic bacteria and marine free-living, saprophytic, and pathogenic bacteria on seagrass leaves and abiotic surfaces was performed to prove the occurrence of true epiphytes of zostera marina and to elucidate the bacterium-plant symbiotrophic relationships. it was shown that in the course of adhesion to the seagrass leaves of two taxonomically different bacteria, cytophaga sp. kmm 3552 and pseudoalteromonas citrea kmm 461, isolated from the seagrass surfa ...200717974207
reclassification of alteromonas fuliginea (romanenko et al. 1995) as pseudoalteromonas fuliginea comb. nov. and an emended description.a new aerobic marine bacterium, strain s3431, was isolated from swab samples of an unidentified polychaete near canal concepción, chile. this strain was thought to represent a new taxon within the genus pseudoalteromonas. although dna-dna reassociation values showed less than 70 % genomic dna relatedness to established pseudoalteromonas type strains, it shared 78 % dna-dna relatedness with alteromonas fuliginea dsm 15748 (=kmm 216) (romanenko et al., 1994). a. fuliginea has later been considered ...201627380907
