| sphingomonas yabuuchiae sp. nov. and brevundimonas nasdae sp. nov., isolated from the russian space laboratory mir. | on the basis of phenotypic and genotypic characteristics and 16s rrna gene sequence analysis, novel species belonging to the genera sphingomonas and brevundimonas were identified from samples taken from the russian space laboratory mir. strain a1-18(t) was isolated from the air. 16s rdna sequence analysis showed that strain a1-18(t) formed a coherent cluster with sphingomonas sanguinis, sphingomonas parapaucimobilis, sphingomonas paucimobilis and sphingomonas roseiflava with sequence similarity ... | 2004 | 15143030 |
| sphingomonas pseudosanguinis sp. nov., isolated from the water reservoir of an air humidifier. | a yellow-pigmented bacterial isolate, strain g1-2(t), obtained from the surface of an air humidifier, was characterized taxonomically. 16s rrna gene sequence analysis, physiological characterization and estimation of the ubiquinone and polar lipid patterns and fatty acid composition revealed that strain g1-2(t) was similar to sphingomonas yabuuchiae and sphingomonas sanguinis, but also showed pronounced differences. on the basis of these results, a novel species of the genus sphingomonas is desc ... | 2007 | 17551055 |
| extracellular lipase and protease production from a model drinking water bacterial community is functionally robust to absence of individual members. | bacteria secrete enzymes into the extracellular space to hydrolyze macromolecules into constituents that can be imported for microbial nutrition. in bacterial communities, these enzymes and their resultant products can be modeled as community property. our goal was to investigate the impact of individual community member absence on the resulting community production of exoenzymes (extracellular enzymes) involved in lipid and protein hydrolysis. our model community contained nine bacteria isolate ... | 2015 | 26599415 |
| diversity of bacterial species in the nasal cavity of sheep in the highlands of ethiopia and first report of histophilus somni in the country. | a study was conducted to isolate bacterial species/pathogens from the nasal cavity of apparently healthy and pneumonic sheep. nasal swabs were collected aseptically, transported in tryptose soya broth and incubated for 24 h. then, each swab was streaked onto chocolate and blood agar for culture. bacterial species were identified following standard bacteriological procedures. accordingly, a total of 1,556 bacteria were isolated from 960 nasal swabs collected from three different highland areas of ... | 2013 | 23328945 |
| [inactivation of the chlorine-resistant bacteria isolated from the drinking water distribution system]. | inactivation experiments of seven strains of chlorine-resistant bacteria, isolated from a drinking water distribution system, were conducted with four kinds of disinfectants. all the bacteria showed high resistance to chlorine, especially for mycobacterium mucogenicum. the ct value of 99.9% inactivation for m. mucogenicum, sphingomonas sanguinis and methylobacterium were 120 mg x (l x min)(-1), 7 mg x (l x min)(-1) and 4 mg x (l x min)(-1), respectively. the results of inactivation experiments s ... | 2012 | 22452196 |
| sphingomonas morindae sp. nov., isolated from noni (morinda citrifolia l.) branch. | two yellow bacterial strains, designated nbd5(t) and nbd8, isolated from noni (morinda citrifolia l.) branch were investigated using a polyphasic taxonomic approach. cells were gram-stain-negative, aerobic, non-spore-forming, non-motile and short rod-shaped. phylogenetic analysis based on 16s rrna gene sequences suggested that the strains were members of a novel species of the genus sphingomonas, the seven closest neighbours being sphingomonas oligoaromativorans sy-6(t) (96.9% similarity), sphin ... | 2015 | 25985831 |
