MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202521134097 A) filed by Dr. Govind Gupta; Mr. Ujwal Virkhare; Ms. Yogita Chouhan; and Dr. Amar Bahadur Singh, Bhopal, Madhya Pradesh, on Dec. 31, 2025, for 'a stress-conditioned, environment-responsive bioinoculant system and method for producing drought-tolerant bacillus-based agricultural compositions.'
Inventor(s) include Dr. Govind Gupta; Mr. Ujwal Virkhare; Ms. Yogita Chouhan; and Dr. Amar Bahadur Singh.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "A Stress-Conditioned, Environment-Responsive Bioinoculant System and Method for Producing Drought-Tolerant Bacillus-Based Agricultural Compositions The present invention relates to a method and composition for producing a drought-tolerant bioinoculant based on stress-tolerant Bacillus species for improving plant resilience under water-limited conditions. The method comprises culturing selected Bacillus species followed by multi-stage stress conditioning, including incremental osmotic stress exposure, thermal-desiccation cycling, and metabolic priming, to induce durable drought-adaptive physiological traits and stress memory in the microorganisms. The stress-conditioned Bacillus species are subsequently incorporated into a hydro-responsive carrier matrix to obtain a stable bioinoculant composition. The composition remains substantially dormant under normal soil moisture conditions and undergoes controlled microbial activation and release in response to reduced soil water availability, enabling sustained rhizosphere colonization and functional activity during drought stress."
