| polychlorinated biphenyl (pcb)-degrading bacteria associated with trees in a pcb-contaminated site. | the abundance, identities, and degradation abilities of indigenous polychlorinated biphenyl (pcb)-degrading bacteria associated with five species of mature trees growing naturally in a contaminated site were investigated to identify plants that enhance the microbial pcb degradation potential in soil. culturable pcb degraders were associated with every plant species examined in both the rhizosphere and root zone, which was defined as the bulk soil in which the plant was rooted. significantly high ... | 2006 | 16597927 |
| molecular analysis of lichen-associated bacterial communities. | the bacterial communities associated with 11 different lichen samples (belonging to eight different species) from different habitats were investigated. the culturable aerobic-heterotrophic fraction of the bacterial communities was isolated from nine lichen samples on protein-rich and sugar-rich/n-free media. thirty-four bacterial isolates were purified and pooled into groups (phylotypes) by analysis of the ribosomal internal transcribed spacer polymorphism. twenty five phylotypes were identified ... | 2006 | 16907761 |
| in vitro suppression of fungi caused by combinations of apparently non-antagonistic soil bacteria. | we hypothesized that apparently non-antagonistic soil bacteria may contribute to suppression of fungi during competitive interactions with other bacteria. four soil bacteria (brevundimonas sp., luteibacter sp., pedobacter sp. and pseudomonas sp.) that exhibited little or no visible antifungal activity on different agar media were prescribed. single and mixed strains of these species were tested for antagonism on a nutrient-poor agar medium against the plant pathogenic fungi fusarium culmorum and ... | 2007 | 17233750 |
| impact of chlorophenols on microbiota of an unpolluted acidic soil: microbial resistance and biodegradation. | the impact of 2-monochlorophenol (mcp), 2,4,6-trichlorophenol (tcp) and pentachlorophenol (pcp) on the microbial community of an acidic forest soil was studied under controlled laboratory conditions by spiking microcosms with the pollutants at concentrations ranging from 0.1 to 5000 mg kg(-1) . a decrease in the cumulative respirometric values and changes in the bacterial and fungal community composition were detected at 1000 mg mcp kg(-1) , 100 mg tcp kg(-1) and 100 and 1000 mg pcp kg(-1) . how ... | 2011 | 21426365 |
| luteibacter jiangsuensis sp. nov.: a methamidophos-degrading bacterium isolated from a methamidophos-manufacturing factory. | a gram-stain-negative, non-motile, rod-shaped bacterial strain, jw-64-1(t), capable of degrading methamidophos was isolated from a methamidophos-manufacturing factory in china, and was subjected to a polyphasic taxonomic investigation. strain jw-64-1(t) produced circular, smooth, transparent, yellow-colored colonies (1.0-2.0 mm) on lb agar after 2 days incubation. it grew optimally at 25-30°c and ph 7.0 without the presence of nacl. the g+c content of the total dna was 63.6 mol%. a phylogenetic ... | 2011 | 20628745 |
| dyella thiooxydans sp. nov., a facultatively chemolithotrophic, thiosulfate-oxidizing bacterium isolated from rhizosphere soil of sunflower (helianthus annuus l.). | a gram-negative, aerobic, motile, rod-shaped, thiosulfate-oxidizing bacterium, designated atsb10(t), was isolated from rhizosphere soil of sunflower (helianthus annuus l.). phylogenetic analysis based on 16s rrna gene sequences revealed that strain atsb10(t) was closely related to members of the genera dyella (96.4-98.1 % 16s rrna gene sequence similarity) and luteibacter (96.4-97.0 %) and fulvimonas soli lmg 19981(t) (96.7 %) and frateuria aurantia ifo 3245(t) (97.8 %). the predominant fatty ac ... | 2011 | 20305058 |
| luteibacter anthropi sp. nov., isolated from human blood, and reclassification of dyella yeojuensis kim et al. 2006 as luteibacter yeojuensis comb. nov. | a yellow-pigmented bacterium was isolated from blood of a 3-year-old boy in göteborg, sweden. comparative analysis of 16s rrna gene sequences showed that this bacterium is most closely related to luteibacter rhizovicinus lj96(t) and dyella yeojuensis r2a16-10(t), with sequence similarity of 98.3 % to both. strain ccug 25036(t) is clearly different from l. rhizovicinus ccug 50033(t) and also from d. yeojuensis dsm 17673(t) in that dna-dna hybridization revealed relatedness of 33.7 and 29.8 %, res ... | 2009 | 19628591 |
| high rate of n2 fixation by east siberian cryophilic soil bacteria as determined by measuring acetylene reduction in nitrogen-poor medium solidified with gellan gum. | for evaluating n(2) fixation of diazotrophic bacteria, nitrogen-poor liquid media supplemented with at least 0.5% sugar and 0.2% agar are widely used for acetylene reduction assays. in such a soft gel medium, however, many n(2)-fixing soil bacteria generally show only trace acetylene reduction activity. here, we report that use of a n(2) fixation medium solidified with gellan gum instead of agar promoted growth of some gellan-preferring soil bacteria. in a soft gel medium solidified with 0.3% ge ... | 2009 | 19286791 |
| dyella ginsengisoli sp. nov., isolated from soil of a ginseng field in south korea. | a gram-negative, aerobic, yellow-pigmented, non-spore-forming, motile, rod-shaped bacterium, designated strain gsoil 3046(t), was isolated from soil from a ginseng field in pocheon province, south korea, and was characterized taxonomically by using a polyphasic approach. a comparative analysis of 16s rrna gene sequences revealed that strain gsoil 3046(t) belongs to the family xanthomonadaceae in the gammaproteobacteria. the greatest sequence similarity was found with respect to dyella koreensis ... | 2009 | 19244422 |
| microbial transformation of cephalomannine by luteibacter sp. | luteibacter sp., a new bacterium isolated from the soil around a taxus cuspidata sieb. et zucc plant, was studied for its capability to metabolize cephalomannine (1). after preparative fermentation, eight metabolites were obtained and characterized as baccatin iii (2), baccatin v (3), 10-deacetylbaccatin iii (4), 10-deacetyl-10-oxobaccatin v (5), 7-epicephalomannine (6), 10-deacetylcephalomannine (7), 10-deacetyl-7-epicephalomannine (8), and 3'-n-debenzoyl-3'-n-(2-methylbutyryl)-7-epitaxol (9). ... | 2007 | 18001087 |
| first reported infections caused by three newly described genera in the family xanthomonadaceae. | members of the family of xanthomonadaceae are typically characterized as environmental organisms. with the exception of stenotrophomonas maltophilia, these organisms are infrequently implicated as human pathogens. we describe three cases of central venous catheter-associated bloodstream infections caused by dokdonella koreensis, aquimonas voraii, and a luteibacter sp., all newly named genera within the family xanthomonadaceae. the three patients all had histories of underlying hematological diso ... | 2007 | 17122001 |
