| rudanella lutea gen. nov., sp. nov., isolated from an air sample in korea. | an orange-coloured bacterial strain, designated 5715s-11(t), was isolated from an air sample in suwon, republic of korea. the strain was strictly aerobic, gram-negative, non-spore-forming, non-flagellated and rod-shaped, frequently forming filaments. growth of the strain was observed at 4-40 degrees c (optimum, 30 degrees c), ph 6.0-8.0 (optimum, ph 7.0) and 0-2 % (w/v) nacl. phylogenetically, strain 5715s-11(t) was shown to be a member of the family spirosomaceae within the phylum bacteroidetes ... | 2008 | 18218952 |
| fibrella aestuarina gen. nov., sp. nov., a filamentous bacterium of the family cytophagaceae isolated from a tidal flat, and emended description of the genus rudanella weon et al. 2008. | a gram-staining-negative, pink bacterium, designated strain buz 2(t), was isolated from coastal mud from the north sea (fedderwardersiel, germany). cells were rod-shaped and able to form multicellular filaments. growth after 7 days was observed at 10-40 °c, at ph 6-8 and with 0-0.5 % nacl. the phylogenetic tree based on 16s rrna gene sequences indicated that strain buz 2(t) is a member of the family cytophagaceae, its closest neighbours being rudanella lutea 5715s-11(t), spirosoma linguale lmg 1 ... | 2011 | 20190021 |
| fibrisoma limi gen. nov., sp. nov., a filamentous bacterium isolated from tidal flats. | an orange-pigmented, gram-staining-negative, non-motile, filament-forming, rod-shaped bacterium (buz 3(t)) was isolated from a coastal mud sample from the north sea (fedderwardersiel, germany) and characterized taxonomically using a polyphasic approach. according to 16s rrna gene sequence data, it belonged to the family cytophagaceae, exhibiting low 16s rrna gene sequence similarity (<90 %) with members of the genera spirosoma, rudanella and fibrella. the dna g+c content was 52.0 mol%. the major ... | 2010 | 20601484 |
| interspecies variation in survival and growth of filamentous heterotrophic bacteria in response to uvc radiation. | ultraviolet radiation is an important environmental constraint on the evolution of life. in addition to its harmful effects, ultraviolet radiation plays an important role in generating genetic polymorphisms and acting as a selective agent. understanding how prokaryotes cope with high radiation can give insights on the evolution of life on earth. four representative filamentous bacteria from the family cytophagaceae with different pigmentation were selected and exposed to different doses of uvc r ... | 2011 | 21530299 |
