| rubellimicrobium thermophilum gen. nov., sp. nov., a red-pigmented, moderately thermophilic bacterium isolated from coloured slime deposits in paper machines. | six red-pigmented strains of the alphaproteobacteria with optimal growth between 45 and 54 degrees c were previously isolated from coloured biofilms in two fine-paper machines and one pulp dryer. the strains were found to be resistant to 15 p.p.m. 2,2-dibromo-3-nitrilopropionamide, a common industrial biocide. 16s rna gene sequence similarity of the isolates was 99.7-100 %. ribotyping using the restriction enzymes pvuii and ecori showed that four of the isolates (c-lvk-r2a-1, c-lvk-r2a-2(t), c-r ... | 2006 | 16738114 |
| wenxinia marina gen. nov., sp. nov., a novel member of the roseobacter clade isolated from oilfield sediments of the south china sea. | an aerobic and heterotrophic, gram-negative bacterial isolate, strain hy34(t), was isolated from sediment of an oilfield in the south china sea, china. the taxonomy of strain hy34(t) was studied by phenotypic and phylogenetic methods. strain hy34(t) formed faint-pink colonies on marine agar 2216. cells of strain hy34(t) were non-motile, ovoid or short rods. strain hy34(t) was positive for catalase and oxidase, and nitrate was reduced to nitrite. the nearly complete 16s rrna gene sequence of stra ... | 2007 | 17684242 |
| rubellimicrobium mesophilum sp. nov., a mesophilic, pigmented bacterium isolated from soil. | a pink- to light-reddish-pigmented, aerobic, pointed, budding, mesophilic strain designated msl-20t was isolated from soil from bigeum island, korea. the isolate was gram-negative. cells were motile rods without flagella. the temperature and ph for growth were 20-37 degrees c (optimum 28 degrees c) and ph 7.0-11.0 (optimum ph 7.0+/-0.2). q-10 was the predominant respiratory ubiquinone. the major fatty acids were c16:0 (37 %), c18: 1 omega7c (36 %) and 11-methyl c18:1 omega7c (12 %). phylogenetic ... | 2008 | 18676459 |
| rubellimicrobium aerolatum sp. nov., isolated from an air sample in korea. | a pink-coloured bacterial strain, designated 5715s-9(t), was isolated from an air sample collected in suwon, republic of korea. the cells were strictly aerobic, gram-negative, non-spore-forming, non-flagellated and short-rod-shaped. on the basis of 16s rrna gene sequence analysis, the organism was a member of the genus rubellimicrobium, showing the highest sequence similarities with rubellimicrobium mesophilum msl-20(t) (96.2 % sequence similarity) and rubellimicrobium thermophilum dsm 16684(t) ... | 2009 | 19196786 |
| rubellimicrobium roseum sp. nov., a gram-negative bacterium isolated from the forest soil sample. | a novel pink-coloured, non-spore-forming, non-motile, gram-negative bacterium, designated yim 48858(t), is described by using a polyphasic approach. the strain can grow at ph 6.5-9 (optimum at ph 7) and 25-30 degrees c (optimum at 28 degrees c). nacl is not required for its growth. positive for oxidase and catalase. urease activity, nitrate reduction, starch and tween 80 tests are negative reaction. 16s rrna gene sequence similarity studies showed that strain yim 48858(t) is a member of the genu ... | 2010 | 20567903 |
| Desert farming benefits from microbial potential in arid soils and promotes diversity and plant health. | To convert deserts into arable, green landscapes is a global vision, and desert farming is a strong growing area of agriculture world-wide. However, its effect on diversity of soil microbial communities, which are responsible for important ecosystem services like plant health, is still not known. | 2011 | 21912695 |
