Benign bacterium could be vital tool in fight against HIV. 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. Rhizobial strains were isolated from the root nodules of Medicago sativa alfalfa and Trifolium subterraneum clover plants.

Pero, a su vez, este proceso tambien esta controlado por factores externos entre los que el nivel de nitrogeno y las cepas de Rhizobium presentes en el suelo son de especial importancia Patriarca et al. En el tercer ensayo se realizaron pruebas bioquimicas para caracterizar las cepas y pronosticar el posible comportamiento en el suelo, descartandose las cepas CIAT por crecer en medio glucosa- peptona-agar, y CIAT por presentar crecimiento atipico. Only a few very effective strains were seen to compete well in the soil.

El rendimiento de la var.

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 2nd trial measured the tolerance in vitro of the strains to grow under low temp.

These strains were tested for their growth rate, morphological characteristics and utilization of different carbon sources. Competitiveness of introduced Rhizobium strains for nodulation in fodder legumes. Legumes; rhizobium ; nodulation.

Significant differences were found between the strains. En el cuarto ensayo rhizobbium midio la efectividad potencial en condiciones controladas, de las distintas cepas sobre las var. The isolated strains MS4 and TS1 were found to be most effective and competitive for alfalfa and clover respectively.

The trial with inoculated plants showed that all the isolated strains were effective in nodulation, because they nodulated in the tested legumes.
