MS4 and TS1 are potent strains for the production of bio-fertilizer for fodder legumes. Before Rhizobium radiobacter can become the basis of an anti-HIV vaccine, the scientists need to find a protein to which they can attach the bacterium’s sugar molecules. In the 5th expt.

Competitiveness of introduced Rhizobium strains for nodulation in fodder legumes

Only a few very effective strains were seen to compete well in the soil. Los mismos autores han demostrado que la combinacion de cuatro enzimas Cfo, HinfI, MspI y AdeIItienen el mismo poder discriminativo que la combinacion de nueve para separar cepas de Rhizobium en especies.

The yield of Frijolica Enhanced nodulation of leguminous plants roots by mixed culture of Azotobacter vinelandii and Rhizobium. The trial with inoculated plants showed that all the isolated strains were effective in nodulation, because they nodulated in the tested legumes.

The competitive ability of inoculated strains with indigenous population was studied with two local soils selected on the basis of their cropping history in a pot experiment.

Fixing nitrogen for the world. References in periodicals archive? En rhizohium tercer ensayo se realizaron pruebas bioquimicas para caracterizar las cepas y rhizobiuk el posible comportamiento en el suelo, descartandose las cepas CIAT por crecer aisla,iento medio glucosa- peptona-agar, y CIAT por presentar crecimiento atipico.

The nitrogen fixing ability of these strains ranged from – n moles of C2H4 produced h-1g-1 nodule dry weight. For the characterization of the bacterial isolates, their micromorphological, staining and cultural characteristics were studied, as well as some physiologicalbiochemical responses, such as the excretion of acid or base to the culture medium and the cetolactase assay.

The cetolactase test allowed to learn that none of the studied isolates belongs to the Agrobacterium genus.
