Electrophoretic profiles of lipopolysaccharides from Rhizobium strains nodulating Pisum sativum do not reflect phylogenetic relationships between these strains.
Enhancement of the nitrogen fixation efficiency of genetically-engineered Rhizobium with high catalase activity(MICROBIAL PHYSIOLOGY AND BIOTECHNOLOGY)
Journal of bioscience and bioengineering 110(4), 397-402, 2010-10
… The vktA catalase gene, which had been cloned from Vibrio rumoiensis S-1^T having extraordinarily high catalase activity, was introduced into the root nodule bacterium, Rhizobium leguminosarum bv. … leguminosarum cells (free-living) was three orders in magnitude higher than that of the parent cells and this transformant could grow in a higher concentration of exogenous hydrogen peroxide (H_2O_2). …
Hemolysis Hemolysis tests to determine if the bacterium eats hemoglobin. Rhizobium Leguminosarum is Beta meaning it does digest hemoglobin. In order to test this, bacteria is streaked onto a sheep's blood ager plate and ...
