The investigation presented here was accomplished using agglutination and agar gel immunodiffusion techniques to compare Azotobacter agilis s 3at, A. chroococcum Italy AC 16, A. macrocytogenes St. M and A. vinelandii ATCC 12837. It was found that the agglutination titers differed sufficiently to allow partial identification of the four species. The homologous and heterologous systems studied by agar gel immunodiffusion tests showed that each of the four Azoto bacter species differed sufficiently in their soluble antigens to give distinct, identifiable patterns of antigen-antibody reactions on Ouchterlony agar plates. These studies also showed several antigens common to the four species tested and the resultant antigen-antibody cross reactions. The results of these investigations suggest that this approach opens a new avenue for the identification of the organisms of genus Azotobacter and perhaps, by extension, the family Azotobacteraceae.
