| salipiger mucescens gen. nov., sp. nov., a moderately halophilic, exopolysaccharide-producing bacterium isolated from hypersaline soil, belonging to the alpha-proteobacteria. | salipiger mucescens gen. nov., sp. nov. is a moderately halophilic, exopolysaccharide-producing, gram-negative rod isolated from a hypersaline habitat in murcia in south-eastern spain. the bacterium is chemoheterotrophic and strictly aerobic (i.e. unable to grow under anaerobic conditions either by fermentation or by nitrate or fumarate respiration). it does not synthesize bacteriochlorophyll a. catalase and phosphatase are positive. it does not produce acids from carbohydrates. it cannot grow w ... | 2004 | 15388737 |
| palleronia marisminoris gen. nov., sp. nov., a moderately halophilic, exopolysaccharide-producing bacterium belonging to the 'alphaproteobacteria', isolated from a saline soil. | strain b33(t) is a moderately halophilic, exopolysaccharide-producing, gram-negative, non-motile rod isolated from a hypersaline soil bordering a saline saltern on the mediterranean seaboard in murcia (spain). the bacterium is chemoheterotrophic and strictly aerobic. it contains a pink pigment but does not synthesize bacteriochlorophyll a. it requires 0.66 m na+, 0.1 m mg2+ and 0.1 m k+ for optimum growth. it does not produce acid from carbohydrates. it cannot grow with carbohydrates, organic ac ... | 2005 | 16280521 |
| yangia pacifica gen. nov., sp. nov., a novel member of the roseobacter clade from coastal sediment of the east china sea. | an aerobic, gram-negative bacterial isolate, strain dx5-10t, was isolated from coastal sediment of the east china sea. the taxonomy of strain dx5-10t was studied by phenotypic and phylogenetic methods. strain dx5-10t was motile, formed faint-yellowish colonies and was positive for catalase reaction and weakly positive for oxidase reaction. the nearly complete 16s rrna gene of strain dx5-10t was obtained and sequence analysis indicated that strain dx5-10t represented an independent lineage within ... | 2006 | 16514022 |
| pelagibaca bermudensis gen. nov., sp. nov., a novel marine bacterium within the roseobacter clade in the order rhodobacterales. | a gram-negative, chemoheterotrophic, facultatively anaerobic, slightly halophilic, oval-shaped marine bacterium, designated htcc2601t, was isolated from the western sargasso sea by high-throughput culturing involving dilution to extinction. although the 16s rrna gene sequence similarity between the isolate and salipiger mucosus was 96.5 %, phylogenetic analyses using different treeing algorithms clearly indicated that the strain forms a distinct lineage within a clade containing the recently cla ... | 2006 | 16585706 |
| donghicola eburneus gen. nov., sp. nov., isolated from seawater of the east sea in korea. | a gram-negative, aerobic, slightly halophilic, non-motile and coccoid- or rod-shaped bacterial strain, sw-277(t), was isolated from seawater, korea, and subjected to a polyphasic taxonomic study. strain sw-277(t) was catalase- and oxidase-positive and grew optimally at ph 7.0-8.0 and 37 degrees c in the presence of 2 % (w/v) nacl. phylogenetic analysis based on 16s rrna gene sequences showed that strain sw-277(t) belongs to the alphaproteobacteria as part of the clade comprising the genera rosei ... | 2007 | 17220445 |
| tranquillimonas alkanivorans gen. nov., sp. nov., an alkane-degrading bacterium isolated from semarang port in indonesia. | strain a34(t), an obligately halophilic, gram-negative, non-motile, rod-shaped bacterium, was isolated from seawater obtained from semarang port in indonesia. it possesses a pink pigment and degrades short-chain alkanes. it is positive for catalase and oxidase and reduces nitrate to nitrite. analyses of 16s rrna gene sequences revealed a clear affiliation of this strain with the family 'rhodobacteraceae' in the class alphaproteobacteria, with its closest relatives being salipiger mucosus a3(t) ( ... | 2008 | 18768615 |
| salinihabitans flavidus gen. nov., sp. nov., isolated from a marine solar saltern. | a gram-negative, non-motile and rod-shaped bacterial strain, isl-46(t), belonging to the alphaproteobacteria, was isolated from a marine solar saltern in korea, and subjected to a polyphasic taxonomic study. strain isl-46(t) grew optimally at ph 7.0-8.0 and 30 degrees c and in the presence of 7 % (w/v) nacl. it contained q-10 as the predominant ubiquinone and c(19 : 0) cyclo omega8c, c(18 : 1)omega7c and 11-methyl c(18 : 1)omega7c as the major fatty acids. the dna g+c content was 63.5 mol%. stra ... | 2009 | 19622639 |
| characterization of the exopolysaccharide produced by salipiger mucosus a3, a halophilic species belonging to the alphaproteobacteria, isolated on the spanish mediterranean seaboard. | we have studied the exopolysaccharide produced by the type strain of salipiger mucosus, a species of halophilic, eps-producing (exopolysaccharide-producing) bacterium belonging to the alphaproteobacteria. the strain, isolated on the mediterranean seaboard, produced a polysaccharide, mainly during its exponential growth phase but also to a lesser extent during the stationary phase. culture parameters influenced bacterial growth and eps production. yield was always directly related to the quantity ... | 2010 | 20948906 |
