MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611010231 A) filed by Ashoka Institute Of Technology And Management; Mr. Aditya Kumar Yadav; Ms. Arpita Singh; Mr. Kashi Yadav; Ms. Kaveri Shivastawa; Mr. Sarvesh Kumar; Dr. Sumedha Ojha; Er. Arifa Siddiqui; and Dr. Sarika Shrivastava, Varanasi, Uttar Pradesh, on Jan. 31, for 'method for isolation and use of root nodule bacteria from legumes to enhance plant growth.'

Inventor(s) include Mr. Aditya Kumar Yadav; Ms. Arpita Singh; Mr. Kashi Yadav; Ms. Kaveri Shivastawa; Mr. Sarvesh Kumar; Dr. Sumedha Ojha; Er. Arifa Siddiqui; and Dr. Sarika Shrivastava.

The application for the patent was published on March 13, under issue no. 11/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a method for isolation, characterization, and agricultural application of root nodule bacteria obtained from leguminous plants for use as a biofertilizer. The invention provides a systematic approach for isolating nitrogen-transforming bacteria from root nodules using selective culture media, followed by biochemical and stress-tolerance characterization to identify agriculturally beneficial strains. The isolated bacteria are formulated with suitable carrier materials and applied to soil for evaluating their effect on plant growth. A comparative experimental study is carried out using a non-leguminous crop, coriander (Coriandrum sativum), under controlled conditions, wherein plant growth parameters, biomass accumulation, chlorophyll content, biochemical composition, and anatomical features are analyzed and compared with chemical fertilizer and untreated controls. The results demonstrate that the bacterial biofertilizer improves plant growth and physiological performance while reducing dependence on synthetic nitrogen fertilizers. The invention thus offers a sustainable, environmentally friendly alternative for enhancing soil fertility and crop productivity in modern agriculture."
