| xenophilus azovorans gen. nov., sp. nov., a soil bacterium that is able to degrade azo dyes of the orange ii type. | the taxonomy of strain kf46ft, which was isolated previously after an aerobic enrichment with the azo compound 1-(4'-carboxyphenylazo)-2-naphthol as the sole source of energy and carbon, was investigated by a polyphasic approach. the organism contained a quinone system with ubiquinone q-8 and 2-hydroxyputrescine and putrescine as the major polyamines, suggesting that strain kf46ft belonged to the beta-subclass of the proteobacteria. the polar lipid profile consisted mainly of phosphatidylethanol ... | 2001 | 11594616 |
| molecular cloning and characterization of the gene coding for the aerobic azoreductase from xenophilus azovorans kf46f. | the gene coding for an aerobic azoreductase was cloned from xenophilus azovorans kf46f (formerly pseudomonas sp. strain kf46f), which was previously shown to grow with the carboxylated azo compound 1-(4'-carboxyphenylazo)-2-naphthol (carboxy-orange ii) as the sole source of carbon and energy. the deduced amino acid sequence encoded a protein with a molecular weight of 30,278 and showed no significant homology to amino acid sequences currently deposited at the relevant data bases. a presumed nad( ... | 2002 | 12147495 |
| emended description of the species lampropedia hyalina. | three lampropedia hyalina strains from different habitats were compared by phenotypic, chemotaxonomic and molecular characteristics. all strains form coccoid cells and have been reported to grow as square tablets of eight to 64 cells. however, two of these strains (atcc 11041t and atcc 43383) have apparently lost this ability, and the third strain may temporarily lose this capacity under certain cultivation conditions. the three strains showed only minor differences in metabolic characteristics: ... | 2004 | 15388733 |
| flow-cytometric cell sorting and subsequent molecular analyses for culture-independent identification of bacterioplankton involved in dimethylsulfoniopropionate transformations. | marine bacterioplankton transform dimethylsulfoniopropionate (dmsp) into the biogeochemically important and climatically active gas dimethylsulfide. in order to identify specific bacterial taxa mediating dmsp processing in a natural marine ecosystem, we amended water samples from a southeastern u.s. salt marsh with 20 microm dmsp and tracked community shifts with flow cytometry (fcm) coupled to 16s rrna gene analyses. in two out of four seasons studied, dmsp amendments induced the formation of d ... | 2005 | 15746343 |
| xenophilus aerolatus sp. nov., isolated from air. | a novel aerobic, gram-negative, motile, rod-shaped bacterial strain designated 5516s-2(t) was isolated from an air sample taken in suwon, republic of korea. colonies were yellow-pigmented and circular with entire margins. 16s rrna gene sequence analysis showed that strain 5516s-2(t) was closely related to xylophilus ampelinus dsm 7250(t) (97.6 % sequence similarity), variovorax soli kacc 11579(t) (97.5 %) and xenophilus azovorans dsm 13620(t) (97.1 %). however, the phylogenetic tree indicated th ... | 2010 | 19651735 |
| characterisation of the flavin-free oxygen-tolerant azoreductase from xenophilus azovorans kf46f in comparison to flavin-containing azoreductases. | the flavin-free azoreductase from xenophilus azovorans kf46f (azob), which has been the very first characterized oxygen-tolerant azoreductase, was analyzed in comparison to various recently described flavin-containing azoreductases from different bacterial sources. sequence comparisons demonstrated that the azoreductase from x. azovorans kf46f is a member of the nmra family of proteins and demonstrates 30% sequence identity with a nadph-dependent quinone oxidoreductase from escherichia coli (enc ... | 2010 | 20508929 |
| Xenophilus aerolatus Peritonitis in a six-year-old boy on maintenance eritoneal dialysis. | Peritonitis remains a significant complication of peritoneal dialysis (PD). Although most patients can be treated successfully with antibiotics and continue PD, the poorest outcomes are noted in patients with peritonitis secondary to gram-negative organisms, which may lead to temporary or permanent technique failure. Biofilm formation may result in. failure of appropriate antibiotic therapy to eradicate infection, necessitating catheter replacement or a switch to hemodialysis. Here, we report th ... | 2011 | 22073828 |
