| the pqqc gene is essential for antifungal activity of pseudomonas kilonensis jx22 against fusarium oxysporum f. sp. lycopersici. | strain jx22, exhibiting a broad range of antimicrobial activities to fungal pathogens, was isolated and classified as representing pseudomonas kilonensis. in this study, the mutant jx22mt1 was obtained by the ez-tn5 transposon mutation and showed no antifungal activity against fusarium oxysporum f. sp. lycopersici as compared with wild-type strain jx22. the pqqc gene was disrupted in the mutant. antifungal activity at the wild-type level was restored from the mutant jx22mt1 with the introduction ... | 2014 | 24588744 |
| effect of metal ions and petrochemicals on bioremediation of chlorpyrifos in aerobic sequencing batch bioreactor (asbr). | application of chlorpyrifos (cp) has increased its environmental concentration. increasing cp concentration has increased chances of adverse health effects. its removal from environment has attained researcher's attention. cp degrading bacterial strains were isolated from wastewater and agricultural soil. finally, selected five bacterial strains were identified using 16s rrna nucleotide sequence analysis as pseudomonas kilonensis srk1, serratia marcescens srk2, bacillus pumilus srk4, achromobact ... | 2016 | 27470246 |
| host-plant selectivity of rhizobacteria in a crop/weed model system. | belowground microorganisms are known to influence plants' performance by altering the soil environment. plant pathogens such as cyanide-producing strains of the rhizobacterium pseudomonas may show strong host-plant selectivity. we analyzed interactions between different host plants and pseudomonas strains and tested if these can be linked to the cyanide sensitivity of host plants, the cyanide production of bacterial strains or the plant identity from which strains had been isolated. eight strain ... | 2007 | 17786217 |
| whole-genome sequence and annotation of octopine-utilizing pseudomonas kilonensis (previously p. fluorescens) strain 1855-344. | here, we report the whole-genome sequence and annotation of pseudomonas kilonensis 1855-344 (previously known as p. fluorescens 1855-344). the genome contains an octopine oxidase gene cluster consistent with the ability to utilize octopine. a biosynthetic gene cluster was identified for mangotoxin and aryl-polyene using the antismash server. | 2015 | 25977435 |
| stress tolerance and genetic variability of phosphate-solubilizing fluorescent pseudomonas from the cold deserts of the trans-himalayas. | nineteen efficient phosphate-solubilizing fluorescent pseudomonas from the cold deserts of the trans-himalayas were screened for stress tolerance against temperature, alkalinity, salinity, calcium salts, and desiccation. phylogenetic analysis based on 16s rrna gene sequencing placed these bacteria under three groups with fourteen strains in group i including pseudomonas trivialis and p. poae, two strains in group ii together with pseudomonas kilonensis and p. corrugata, and three strains in grou ... | 2009 | 19319589 |
| pseudomonas kilonensis sp. nov., a bacterium isolated from agricultural soil. | a total of 131 bacterial isolates related to pseudomonas corrugata were obtained from an agricultural soil from northern germany. based on 16s rrna gene sequences, pcr-based genome fingerprinting and multilocus enzyme electrophoresis, they formed two groups, a (119 strains) and b (12 strains). as members of each group were highly similar, a single strain of each group was subsequently characterized by a polyphasic taxonomic approach. the selected member of group a was identified as a strain of p ... | 2001 | 11491357 |
| bacterial assisted degradation of chlorpyrifos: the key role of environmental conditions, trace metals and organic solvents. | wastewater from pesticide industries, agricultural or surface runoff containing pesticides and their residues has adverse environmental impacts. present study demonstrates effect of petrochemicals and trace metals on chlorpyrifos (cp) biotransformation often released in wastewater of agrochemical industry. biodegradation was investigated using bacterial strain pseudomonas kilonensis srk1 isolated from wastewater spiked with cp. optimal environmental conditions for cp removal were cfu (306 × 10(6 ... | 2016 | 26692411 |
| differential contribution of plant-beneficial functions from pseudomonas kilonensis f113 to root system architecture alterations in arabidopsis thaliana and zea mays. | fluorescent pseudomonads are playing key roles in plant-bacteria symbiotic interactions due to the multiple plant-beneficial functions (pbfs) they are harboring. the relative contributions of pbfs to plant-stimulatory effects of the well-known plant growth-promoting rhizobacteria pseudomonas kilonensis f113 (formerly p. fluorescens f113) were investigated using a genetic approach. to this end, several deletion mutants were constructed, simple mutants δphld (impaired in the biosynthesis of 2,4-di ... | 2018 | 28971723 |
