[determination of the structure of the repeated unit of the azospirillum brasilense sr75 o-specific polysaccharide and homology of the lps loci in the plasmids of azospirillum brasilense strains sr75 and sp245]. | the structural identity of the repeated unit in o-specific polysaccharides (opss) present in the outer membrane of strain sr75 of the bacterium azospirillum brasilense, isolated from wheat rhizosphere in saratov oblast, and the opss of previously studied a. brasilense strain sp245, isolated from surface-sterilized wheat roots in brazil, has been demonstrated. plasmid profiles, dna restriction, and hybridization assays suggested that a. brasilense strains sr75 and sp245 have different genomic str ... | 2005 | 16315981 |
