Azospirilla are generally gram-negative rods which are motile by means of a single flagellum. Azospirilla are also capable of fixing nitrogen. The cells of Azospirillum remain in association with the roots and fix part of the atmospheric nitrogen. Azospirillum species may be isolated from rhizosphere biofilms associated with the roots of various grasses, cereals, and tuber plants. Their isolation is based on the fact that these organisms can grow in concentrations of nitrogen too low to support growth of most microorganisms. Azospirillum cultures are useful for the cereals and cash crops viz. wheat, paddy, bajra, jowar, maize, mustard, cotton, cumin, banana, sugarcane, tobacco, castor, vegetables etc., as well as horticultural crops. Both in greenhouse and in field trials, several strains of Azospirillum have been shown to exert beneficial effects on plant growth and crop yields, under various soil and climatic conditions, and are thus qualified as Plant Growth-Promoting Rhizobacteria.
for cultivation of Azospirillum species.
