Abstract

Bacteria of the genus Azospirillum are gram-negative, facultative anaerobic, rhizosphere-dwelling microorganisms that form symbiotic relationships with plants and significantly stimulate their growth. Their main biological function is molecular nitrogen fixation, which improves the nitrogen balance in the soil and reduces the need for mineral fertilizers. Phytohormones produced by Azospirillum - indole-3-acetic acid (IAA), gibberellins and cytokinins - enhance root development, improve nutrient uptake and increase tolerance to stress factors. Therefore, these bacteria are widely used in agriculture as environmentally safe and cost-effective biological fertilizers.
