ABSTRACT Forty renodulating rhizobial bacteria associated with Vicia faba were collected and isolated from different regions in West Algeria and characterized at phenotypic level. The analysis of their tolerance to salinity high temperature acid and alkaline pH antibiotic resistance and carbon substrates metabolism as well as their symbiotic and cultural characteristics highlighted a wide physiological diversity within this rhizobial population. The numerical analysis of phenotypic characteristics showed that the bacterial strains were grouped into four different clusters. Interesting stains for inoculation trials have been identified they proved their efficiency in addition to their tolerance to 1 and 1.5M of NaCL concentrations and maximum temperatures of 40C.
