Caracterización serológica y molecular de la cepa 8-INICA de Azospirillum brasilense utilizada en la biofertilización de la caña de azúcar.

Azospirillum is a bacterium that produces growth and yields increments due to its capacity of fix atmospheric nitrogen and to produce phytohormones. In Cuba, the 8-INICA strain of Azospirillum sp. has been used successfully in sugarcane biofertilization and others economical crops. The morphological and biochemical characterization of this stain showed similarity with the species A. brasilense. Due to the importance of this strain in the biofertilization works carried out in our country, the aim of this paper was to confirm the identity of this strain through immunoenzymatic and molecular techniques.
