The paper studies the influence of temperature and humidity on the induction of cyst formation by the bacteria А. vinelandii М-Х, А. chroococcum M-70 and consortium of А. vinelandii and А. chroococcum. It was shown that temperature 44 ºС was the optimal for cyst formation by Аzotobacter in nutrient agar medium. Its drying for 5 days at this temperature (44 ºС) is optimal for encystment in the powdered substrate.
