| shewanella hafniensis sp. nov. and shewanella morhuae sp. nov., isolated from marine fish of the baltic sea. | two novel species belonging to the genus shewanella are described on the basis of their phenotypic characteristics, phylogenetic analyses of 16s rrna and gyrb gene sequences and levels of dna-dna hybridization. a total of 47 strains belonging to two novel gram-negative, psychrotolerant, h2s-producing bacterial species were isolated from marine fish (cod and flounder) caught from the baltic sea off denmark. the phenotypic characteristics of strains belonging to group 1 (14 strains) indicated that ... | 2006 | 16403893 |
| description of shewanella glacialipiscicola sp. nov. and shewanella algidipiscicola sp. nov., isolated from marine fish of the danish baltic sea, and proposal that shewanella affinis is a later heterotypic synonym of shewanella colwelliana. | two novel species belonging to the genus shewanella are described on the basis of a polyphasic taxonomic approach. a total of 40 strains of gram-negative, psychrotolerant, h2s-producing bacteria were isolated from marine fish (cod and plaice) caught in the baltic sea off denmark. strains belonging to group 1 (seven strains) were a lactate-assimilating variant of shewanella morhuae with a g+c content of 44 mol%. the strains of group 2 (33 strains) utilized lactate, n-acetylglucosamine and malate ... | 2007 | 17267977 |
| the microbiota of freshwater fish and freshwater niches contain omega-3 fatty acid-producing shewanella species. | approximately 30 years ago, it was discovered that free-living bacteria isolated from cold ocean depths could produce polyunsaturated fatty acids (pufa) such as eicosapentaenoic acid (epa) (20:5n-3) or docosahexaenoic acid (dha) (22:6n-3), two pufa essential for human health. numerous laboratories have also discovered that epa- and/or dha-producing bacteria, many of them members of the shewanella genus, could be isolated from the intestinal tracts of omega-3 fatty acid-rich marine fish. if bacte ... | 2015 | 26497452 |
