Short Communication Antibiotic Sensitivities of the Root Nodule Bacteria

Variations in the susceptibility of rhizobia to antibiotic substances have been previously reported. Fogle and Allen (1948) considered lupin and soybean rhizobia to be more susceptible to various 'streptomycete antibiotics than other species of rhizobia. In contrast, Landerkin and Lochhead (1948) noted that strains of Rhizobium japonicum were less susceptible to actinomycete antibiotics than were other soil organisms tested.
