| microvirga subterranea gen. nov., sp. nov., a moderate thermophile from a deep subsurface australian thermal aquifer. | a strictly aerobic bacterium, strain fail4t, was isolated from free-flowing geothermal waters of a bore (bore register no. 3768) tapping the great artesian basin of australia. the non-sporulating, gram-negative cells of strain fail4t produced light-pink colonies, were rod-shaped (1 x 1.5-4 microm) and were motile by a single polar flagellum. strain fail4t grew optimally at 41 degrees c at a ph of 7.0 and had an absolute requirement for yeast extract. the strain grew on casein hydrolysate, trypto ... | 2003 | 12710604 |
| microvirga guangxiensis sp. nov., a novel alphaproteobacterium from soil, and emended description of the genus microvirga. | a gram-negative-staining bacterium, designated strain 25bt, was isolated from a soil sample from a rice field in guangxi province, china, and its taxonomic position was investigated by using a polyphasic approach. cells were rod-shaped, non-spore-forming, non-motile and strictly aerobic. strain 25bt grew optimally at 37 degrees c and ph 7.0. the predominant fatty acids of this soil isolate were c18:1omega7c, c19:0 cyclo omega8c and c16:0. phylogenetic analysis based on the almost-complete 16s rr ... | 2009 | 19567564 |
| salinarimonas rosea gen. nov., sp. nov., a new member of the alpha-2 subgroup of the proteobacteria. | a gram-negative, rod-shaped, facultatively anaerobic, halotolerant bacterial strain, designated yim yd3(t), was isolated from a salt mine in yunnan, south-west china. the taxonomy of strain yim yd3(t) was investigated by a polyphasic approach. strain yim yd3(t) was motile, formed pink colonies and was positive for catalase and oxidase activities. q-10 was the predominant respiratory ubiquinone. the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmethylethanolami ... | 2010 | 19648350 |
| description of microvirga aerophila sp. nov. and microvirga aerilata sp. nov., isolated from air, reclassification of balneimonas flocculans takeda et al. 2004 as microvirga flocculans comb. nov. and emended description of the genus microvirga. | two bacterial strains, 5420s-12(t) and 5420s-16(t), isolated from air samples, were characterized using a polyphasic approach. 16s rrna gene sequence analysis showed that strain 5420s-12(t) was related phylogenetically to microvirga subterranea faii4(t) (97.4 % sequence similarity) and microvirga guangxiensis 25b(t) (97.1 %) and that strain 5420s-16(t) was closely related to balneimonas flocculans tfb(t) (98.0 %) and microvirga guangxiensis 25b(t) (97.2 %). the g+c content of the genomic dna was ... | 2010 | 20023055 |
| microvirga lupini sp. nov., microvirga lotononidis sp. nov., and microvirga zambiensis sp. nov. are alphaproteobacterial root nodule bacteria that specifically nodulate and fix nitrogen with geographically and taxonomically separate legume hosts. | strains of gram-negative, rod-shaped, non-spore-forming bacteria were isolated from nitrogen-fixing nodules of the native legumes listia angolensis (from zambia) and lupinus texensis (from texas, usa). phylogenetic analysis of the 16s rrna gene showed that the novel strains belong to the genus microvirga, with 96.1 % or greater sequence similarity with type strains of this genus. the closest relative of the representative strains lut6t and wsm3557t was m. flocculans tfbt, with 97.6-98.0 % simila ... | 2011 | 22199210 |
