rhizobium alamii sp. nov., an exopolysaccharide-producing species isolated from legume and non-legume rhizospheres. | a group of exopolysaccharide-producing bacteria was isolated from the root environment of arabidopsis thaliana. the genetic diversity revealed by rep-pcr fingerprinting indicated that the isolates correspond to different strains. 16s rrna gene sequence analysis showed that the isolates are closely related to the strains rhizobium sp. yas34 and usda 1920, respectively isolated from sunflower roots and medicago ruthenica nodules. these bacteria belong to the rhizobium lineage of the alphaproteobac ... | 2009 | 19196780 |
modulation of metabolism and switching to biofilm prevail over exopolysaccharide production in the response of rhizobium alamii to cadmium. | heavy metals such as cadmium (cd(2+)) affect microbial metabolic processes. consequently, bacteria adapt by adjusting their cellular machinery. we have investigated the dose-dependent growth effects of cd(2+) on rhizobium alamii, an exopolysaccharide (eps)-producing bacterium that forms a biofilm on plant roots. adsorption isotherms show that the eps of r. alamii binds cadmium in competition with calcium. a metabonomics approach based on ion cyclotron resonance fourier transform mass spectrometr ... | 2011 | 22096497 |
rhizobium halotolerans sp. nov., isolated from chloroethylenes contaminated soil. | the strain designated as ab21(t) was isolated from chloroethylenes contaminated soil. cells are gram-negative, aerobic, non-spore-forming, and motile rods. phylogenetic analysis based on 16s rrna gene sequence showed that it belonged to the genus rhizobium, and was closely related to rhizobium sullae is 123(t) (97.4 %), rhizobium yanglingense sh 22623(t) (97.2 %), rhizobium gallicum r 602sp(t) (97.1 %), rhizobium alamii gbv 016(t) (97.0 %), and rhizobium monogolense usda 1844(t) (97.0 %). it sho ... | 2013 | 23377488 |
reclassification of arthrobacter viscosus as rhizobium viscosum comb. nov. | the species arthrobacter viscosus was isolated from soil from guatemala and it was classified into the genus arthrobacter on the basis of phenotypic traits. nevertheless, the results of16s rrna gene analysis indicated that this species is a member of the genus rhizobium, with rhizobium alamii gbv016t and rhizobium mesosinicum ccbau 25010t as the most closely related species with 99.64 and 99.48 % similarity, respectively. the similarity values for the reca gene are 92.2 and 94.4 % with respect t ... | 2017 | 28598309 |
