BIOFERTILIZER

Azospirillum brasilense is a plant growth promoting rhizobacterium (PGPR) that is being increasingly used in agriculture in a commercial scale. Biological nitrogen fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by an enzyme called nitrogenase. Nitrogenases are enzymes used by some organisms to fix atmospheric nitrogen gas (N,). Recent research has elucidated key properties of A. brasilense that contribute to its ability to adapt to the rhizosphere habitat and to promote plant growth. They include synthesis of the auxin indole-3-acetic acid, nitric oxide, carotenoids, and a range of cell surface components as well as the ability to undergo phenotypic variation. Auxins are a major class of phytohormones that are involved in the coordination of plant growth and development. The effects of azospirilla on plant root morphology (e.g. elongation of primary roots and increase of the number and length of lateral roots) have been shown to correlate with exogenous levels of the auxin indole-3-acetate (IAA),

• Enhancement of root elongation and branching
• Enhancement of water and mineral uptake by roots and improvement of water/mineral status of the plant
• Increase of leaf surface area and stem diameter; improvement of tillering and yield
• Improvement of respiration rate, enzymatic activity, and hydrolysis of glycosides, and auxin and gibberellin conjugates; changes in root secondary metabolites
• Improvement of growth by ammonium- secreting strains
• Increase in biological nitrogen fixation and nitrogen enrichment in roots.
• Enhanced flavonoid signaling, nodulation, and nitrogen fixation in co-inoculation with rhizobia.
