| porphyrobacter donghaensis sp. nov., isolated from sea water of the east sea in korea. | two gram-negative, motile, non-spore-forming, bacteriochlorophyll a-containing slightly halophilic strains, sw-132(t) and sw-158, were isolated from sea water of the east sea in korea, and subjected to a polyphasic taxonomic study. the two isolates were characterized chemotaxonomically as having q-10 as the predominant respiratory lipoquinone and major amounts of unsaturated fatty acids c(18 : 1)omega7c and c(17 : 1)omega6c. the dna g+c contents of the two strains were in the range 66.8-65.9 mol ... | 2004 | 15545463 |
| [new strains of an aerobic anoxygenic phototrophic bacterium porphyrobacter donghaensis isolated from a siberian thermal spring and a low-mineralization lake]. | a strain of aerobic anoxygenic phototrophic bacteria (aapb) isolated from the surface of a cyano- bacterial mat of an eastern siberian thermal spring (40 c) and designated se 4 was identified as porphyro- bacter donghaensis according to its 16s rrna gene sequence. a dna-dna hybridization level of 95% was determined between strain se-4 and the type strain of this species; sw-132@t. the isolate was an obligate aerobe,. forming orange round colonies on solid media, which turn red in the course of g ... | 2016 | 27301129 |
| identification of yellow-pigmented bacteria isolated from hospital tap water in japan and their chlorine resistance. | twenty-five yellow chromogenic strains isolated from hospital tap water samples collected nationwide were identified by partial 16s rdna sequencing. in addition, the chlorine resistance of the isolates was experimentally investigated. the results showed that of the strains tested, 12 strains (48.0%) were sphingomonas ursincola/natatoria, which was most frequently identified, followed by 2 strains (8.0%) of mycobacterium frederiksbergense and 1 strain (4.0%) each of sphingomonas adhaesiva, sphing ... | 2007 | 17629244 |
