rhizobium miluonense sp. nov., a symbiotic bacterium isolated from lespedeza root nodules.	seventeen strains of lespedeza rhizobia, a previously defined novel group, were further characterized by comparison with phylogenetically related species using a polyphasic approach, including sds-page of whole-cell proteins, pcr-based restriction fragment length polymorphism analysis of ribosomal intergenic spacer sequences, determination of dna g+c contents, dna-dna hybridization and analysis of phenotypic features. based on data obtained in the present and previous studies, a novel species, r ...	2008	18523179
reclassification of rhizobium tropici type a strains as rhizobium leucaenae sp. nov.	rhizobium tropici is a well-studied legume symbiont characterized by high genetic stability of the symbiotic plasmid and tolerance to tropical environmental stresses such as high temperature and low soil ph. however, high phenetic and genetic variabilities among r. tropici strains have been largely reported, with two subgroups, designated type a and b, already defined within the species. a polyphasic study comprising multilocus sequence analysis, phenotypic and genotypic characterizations, inclu ...	2011	21742822
optimization of exopolysaccharide production and diesel oil emulsifying properties in root nodulating bacteria.	bioremediation, a strategy mediated by microorganisms, is a promising way used in the degradation or removal of organic contaminants from soil or aquatic system. exopolysaccharide (eps) which was produced by a variety of gram-negative bacteria has been demonstrated to be a potential bioemulsifier used in the degradation of hydrocarbons. in the present study, attempts were made to optimize the production of eps from our newly isolates by adjusting the culture conditions and medium components. bes ...	2011	22805917
igneous phosphate rock solubilization by biofilm-forming mycorrhizobacteria and hyphobacteria associated with rhizoglomus irregulare daom 197198.	biofilm formation on abiotic and biotic surfaces was studied with two hyphobacteria, strongly attached to the surface of the arbuscular mycorrhizal fungus (amf) rhizoglomus irregulare (ri) daom 197198 and two mycorrhizobacteria, loosely attached to the roots of different mycorrhizal plants. when the sparingly soluble igneous phosphate rock (pr) from quebec, or when the chemical hydroxyapatite were used as sole phosphorus (p) source, hyphobacteria rhizobium miluonense rm3 and burkholderia anthina ...	2016	27541158
differential colonization by bioprospected rhizobial bacteria associated to common bean in different cropping systems <i></i>.	in this study, we evaluated the diversity of rhizobia isolated from root nodules on common bean (<i>phaseolus vulgaris</i>) derived from andean and mesoamerican centers and grown under field and greenhouse conditions. genetic characterization of isolates was performed by sequencing analyses of the 16s rrna and two housekeeping genes, <i>rec</i>a and <i>gln</i>ii, and by the amplification of <i>nif</i>h. symbiotic efficiency was evaluated by examining nodulation, plant-biomass production and plan ...	2017	28376308
