Q. What is a azospirillum biofertilizer?

Answer

The biofertilizer's Azospirillum bacteria can invade plant roots and convert air nitrogen into a form that plants can use. It is thought to aid plant growth by increasing the plant's tolerance to abiotic and biotic stress through the synthesis of phytohormones, in particular indole-3-acetic acid. The bacterial genus Azospirillum belongs to the Rhodospirillaceae family and is Gram-negative, microaerophilic, non-fermentative, and nitrogen-fixing. Plants can benefit from the presence of azospirillum bacteria. In 1925, M.W. Beijerinck described the first member of the genus, which he named Spirillum lipoferum. Dr. Johanna Döbereiner and her team of Brazilian researchers discovered strains of this species linked to the roots of grain plants in the 1970s.
