| 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 |
| classification of a brevundimonas strain detectable after pcr with a helicobacter-specific primer pair. | in a study for the isolation of new helicobacter strains, biopsy samples were taken from the gastric mucosa of dogs and subjected to pcr amplification using a helicobacter-specific primer pair (h276f and h676r, directed to the 16s rdna) to identify members of this genus in the specimens. from one helicobacter positive sample, a bacterial strain was isolated which displayed a characteristic band after pcr amplification with the helicobacter-specific primer pair. the isolate designated h2/98-fundu ... | 2001 | 11822672 |
| optimization of the ipp precursor supply for the production of lycopene, decaprenoxanthin and astaxanthin by corynebacterium glutamicum. | the biotechnologically relevant bacterium corynebacterium glutamicum, currently used for the million ton-scale production of amino acids for the food and feed industries, is pigmented due to synthesis of the rare cyclic c50 carotenoid decaprenoxanthin and its glucosides. the precursors of carotenoid biosynthesis, isopenthenyl pyrophosphate (ipp) and its isomer dimethylallyl pyrophosphate, are synthesized in this organism via the methylerythritol phosphate (mep) or non-mevalonate pathway. termina ... | 2014 | 25191655 |
| a carotenoid synthesis gene cluster from a non-marine brevundimonas that synthesizes hydroxylated astaxanthin. | a brevundimonas vesicularis strain dc263 isolated from surface soil was shown to produce hydroxylated astaxanthin. a carotenoid synthesis gene cluster containing ten genes was cloned from strain dc263, among which eight genes were involved in carotenoid synthesis. in addition to the crtw gene encoding the 4,4'-beta-ionone ring ketolase and the crtz gene encoding the 3,3'-beta-ionone ring hydroxylase that were responsible for astaxanthin synthesis, the cluster also contained a novel gene crtg ide ... | 2006 | 16781830 |
| phylogeny and polyphasic taxonomy of caulobacter species. proposal of maricaulis gen. nov. with maricaulis maris (poindexter) comb. nov. as the type species, and emended description of the genera brevundimonas and caulobacter. | the genus caulobacter is composed of prosthecate bacteria often specialized for oligotrophic environments. the taxonomy of caulobacter has relied primarily upon morphological criteria: a strain that visually appeared to be a member of the caulobacter has generally been called one without challenge. a polyphasic approach, comprising 16s rdna sequencing, profiling restriction fragments of 16s-23s rdna interspacer regions, lipid analysis, immunological profiling and salt tolerance characterizations ... | 1999 | 10425763 |
| brevundimonas albigilva sp. nov., isolated from forest soil. | strain nhi-13t, a gram-negative, aerobic, and short rod-shaped bacterium, was isolated from forest soil at kyonggi university in suwon, south korea. it grew optimally in r2a medium, at 28-35 °c, in the presence of 0-4% nacl. colonies resulting from incubation of the strain on agar plates for 2 days were circular, raised, translucent, viscous and whitish yellow-coloured, with entire margins. this strain exhibited high catalase activity but was negative for oxidase. 16s rrna gene sequence analysis ... | 2015 | 26674350 |
| brevundimonas balnearis sp. nov., isolated from the well water of a thermal bath. | a novel alphaproteobacterium was isolated from the well water of a thermal bath at budapest, hungary. phylogenetic analysis of the new strain showed that this bacterium belongs to a distinct lineage among the genus brevundimonas. based on the 16s rrna gene sequence strain fdrgb2bt shows the highest sequence similarity values to brevundimonas naejangsanensis bio-tas2-2t (97.35%), brevundimonas viscosa f3t (97.28%), brevundimonas vesicularis lmg 2350t (97.27%), brevundimonas nasdae gtc 1043t (97.1 ... | 2016 | 27995874 |
| potential infection control risks associated with ultrasound equipment - a bacterial perspective. | ultrasound equipment used in trans-abdominal (ta) and trans-vaginal (tv) examination may carry bacterial contamination and pose risks to infection control during ultrasound examination. we aimed to describe the prevalence of bacterial contamination on ultrasound probes, gel, machine keyboard and cords and examined the effectiveness of low- and high-level disinfection techniques. this study was performed at a public hospital and a private practice. a total of 171 swabs were analyzed and bacterial ... | 2017 | 28341192 |
