| burkholderia unamae sp. nov., an n2-fixing rhizospheric and endophytic species. | it was shown recently that the genus burkholderia is rich in n2-fixing bacteria that are associated with plants. a group of these diazotrophic isolates with identical or very similar 16s rdna restriction patterns [designated amplified rdna restriction analysis (ardra) genotypes 13, 14 and 15] was selected and a polyphasic taxonomic study was performed, which included new isolates that were recovered from rhizospheres, rhizoplanes or internal tissues of maize, sugarcane and coffee plants. morphol ... | 2004 | 15280286 |
| burkholderia ferrariae sp. nov., isolated from an iron ore in brazil. | a gram-negative, non-spore-forming bacterial strain with the ability to solubilize highly insoluble phosphatic minerals was isolated from a high-phosphorous iron ore from minas gerais state, brazil. this strain, designated fegl01(t), was subjected to a polyphasic taxonomic investigation. comparative 16s rrna gene sequence analysis indicated that it formed a distinct phylogenetic lineage within the genus burkholderia together with several other species of the genus, e.g. burkholderia sacchari, bu ... | 2006 | 17012573 |
| acc (1-aminocyclopropane-1-carboxylate) deaminase activity, a widespread trait in burkholderia species, and its growth-promoting effect on tomato plants. | the genus burkholderia includes pathogens of plants and animals and some human opportunistic pathogens, such as the burkholderia cepacia complex (bcc), but most species are nonpathogenic, plant associated, and rhizospheric or endophytic. since rhizobacteria expressing acc (1-aminocyclopropane-1-carboxylate) deaminase may enhance plant growth by lowering plant ethylene levels, in this work we investigated the presence of acc deaminase activity and the acds gene in 45 strains, most of which are pl ... | 2009 | 19700546 |
| burkholderia bannensis sp. nov., an acidic ph-neutralizing bacterium isolated from torpedo grass (panicum repens) that grows in highly acidic swamps in thailand. | two strains of acidic ph-neutralizing bacteria, e25(t) and e21, were isolated from torpedo grass (panicum repens) that grows in highly acidic swamps (ph 2 - 4) in actual acid sulfate soil areas of thailand. the strains were gram-negative, aerobic, non-spore-forming, and rod-shaped bacteria, having a cellular width of 0.6 - 0.8 microm and a length of 1.6 - 2.1 microm. these strains showed good growth between ph 4.0 and 8.0 and between 17 and 37 degrees c. the organisms contained ubiquinone q-8 as ... | 2010 | 20709915 |
