Isolating Spontaneous Antibiotic-Resistant Mutants of Rhizobiacurring mutants that are resistant to high concentrations of certain antibiotics. This resistance may be used for recognizing rhizobial strains. In this chapter, two strains of . are used to produce spontaneous mutants resistant to streptomycin and spectinomycin. . mutants, with simultaneous resista

enormous economic importance internationally and the subject of intense research interest. Handbook for Rhizobia is a monumental book of practical methods for working with these bacteria and their plant hosts. Topics include the general microbiological properties of rhizobia and their identification
