| high-performance liquid chromatography analyses of pyoverdin siderophores differentiate among phytopathogenic fluorescent pseudomonas species. | the relationship of pyoverdins produced by 41 pathovars of pseudomonas syringae and by phytopathogenic pseudomonas species was investigated. a high-performance liquid chromatography method for analyzing the culture medium proved to be superior to isoelectric focusing for detecting pyoverdin production, for differentiating slightly different pyoverdins, and for differentiating atypical from typical fe(iii)-chelated pyoverdins. nonfluorescent strains were found in pseudomonas amygdali, pseudomonas ... | 2003 | 12571041 |
| plant growth-promoting bacteria facilitate the growth of the common reed phragmites australisin the presence of copper or polycyclic aromatic hydrocarbons. | to test whether plant growth-promoting bacteria might be useful in facilitating the growth of phragmites australis, the common reed, in the presence of metals and organic compounds, p. australis seeds were treated with plant growth-promoting bacteria. the bacterium pseudomonas asplenii ac was genetically transformed to express a bacterial gene encoding the enzyme 1-aminocyclopropane-1-carboxylate deaminase, and both the native and transformed bacteria were tested in conjunction with p. australis ... | 2005 | 16328627 |
| growth of canola (brassica napus) in the presence of plant growth-promoting bacteria and either copper or polycyclic aromatic hydrocarbons. | growth of canola (brassica napus) seeds treated with plant growth-promoting bacteria in copper-contaminated and polycyclic aromatic hydrocarbon (pah)-contaminated soils was monitored. pseudomonas asplenii ac, isolated from pah-contaminated soil, was transformed to express a bacterial gene encoding 1-aminocyclopropane-1-carboxylate (acc) deaminase, and both native and transformed bacteria were tested for growth promotion. inoculation of seeds, grown in the presence of copper or creosote, with eit ... | 2005 | 16462865 |
| biofilm formation and cellulose expression among diverse environmental pseudomonas isolates. | the ability to form biofilms is seen as an increasingly important colonization strategy among both pathogenic and environmental bacteria. a survey of 185 plant-associated, phytopathogenic, soil and river pseudomonas isolates resulted in 76% producing biofilms at the air-liquid (a-l) interface after selection in static microcosms. considerable variation in biofilm phenotype was observed, including waxy aggregations, viscous and floccular masses, and physically cohesive biofilms with continuously ... | 2006 | 17014498 |
| pseudomonas moraviensis sp. nov. and pseudomonas vranovensis sp. nov., soil bacteria isolated on nitroaromatic compounds, and emended description of pseudomonas asplenii. | two strains of gram-negative bacteria isolated from soil by selective enrichment with nitroaromatics were subjected to a polyphasic taxonomic study. on the basis of 16s rrna gene sequence analysis, the two strains were found to belong to the genus pseudomonas, within the gammaproteobacteria. strain 1b4t shared the highest sequence similarity with pseudomonas koreensis dsm 16610t (99.5%) and pseudomonas jessenii ccm 4840t (99.3%), and strain 2b2t with pseudomonas asplenii dsm 17133t (98.9%), pseu ... | 2006 | 17082407 |
| in vitro evaluation of pseudomonas bacterial isolates from rice phylloplane for biocontrol of rhizoctonia solani and plant growth promoting traits. | the ability for biocontrol and plant growth promotion of three pseudomonas bacterial isolates namely pseudomonas fluorescens (umb20), pseudomonas aeruginosa (kmb25) and pseudomonas asplenii (bmb42) obtained from rice plants was investigated. fungal growth inhibition by the isolates ranged from 86.85 to 93.15% in volatile and 100% in diffusible metabolites test. among the isolates, bmb42 showed fungal growth inhibition significantly in the volatile metabolite test. isolates umb20 and bmb42 were a ... | 2016 | 27498507 |
| pseudomonas hunanensis sp. nov., isolated from soil subjected to long-term manganese pollution. | a gram-negative, polar flagella, rod-shaped bacterium lv (t) was isolated from a soil sample subjected to long-term manganese pollution in hunan province, china. cells grow optimally on luria-bertani agar medium at 30 °c in the presence of 0-5.0 % (w/v) nacl and ph 7-8. 16s rrna gene sequence analysis revealed that strain lv (t) belonged to the genus pseudomonas, with sequence similarity values of 98.6, 98.2, 98.7, and 97.3 % to pseudomonas monteilii bcrc 17520 (t) , pseudomonas putida bcrc 1045 ... | 2014 | 24562759 |
| a mutualistic interaction between the bacterium pseudomonas asplenii and the harmful algal species chattonella marina (raphidophyceae). | several studies on various chattonella species have reported that bacteria may play an important role in chattonella bloom initiation, however, no studies have described how these bacteria promote the growth of c. marina. the interaction between c. marina and bacteria was investigated for identification and characterization of potential growth-promoting bacteria. in preliminary tests, the growth promoting effect of pseudomonas species (25 strains) was investigated and p. asplenii (≥2.27) was det ... | 2016 | 28073494 |
