Eighteen strains of rhizobia were isolated from root nodules of Colutea arborescens grown in the different soils of the eastern region of Morocco. These strains are able to grow under different stress conditions. Many strains tolerate high salt concentrations and all of them grow at 35°C and in media with pH values ranging from 6 to 9. They also show resistance to several antibiotics at the concentrations used. The tolerance level to heavy metals is diverse and depends on the strains and the concentrations used.
