Summary:Azofert[R] is a biofertilizer with a diazotrophic bacteria named rhizobia for the legumes inoculation. The present work aimed to evaluate the microbiological quality of the Azofert[R] -F and Azofert[R] -S biofertilizers with. Inoculants were made from two strains Rhizobium leguminusarum and Brayrhizobium elkanii and it was stored at 4 and 32 [degrees]C. The concentration of both strains was determined by the serial dilutions method. In addition, the presence of contaminants in the inoculants was determined by Gram staining. Results showed that inoculants of both strains remained pure throughout the experiment. The inoculants stored at 4 [degrees]C maintained a cell concentration of 10 (8) CFU mL for longer. This concentration is suitable for the use of these products in the field. These results allow establishing a productive strategy of the Azofert[R] -F and Azofert[R] -S Cuban inoculants, according to the available temperature conditions.
