MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202511019494 A) filed by Amity University on March 04, 2025, for Method Of Developing A Novel Bio Npk Consortium Of Talaromyces Albobiverticillius (hnb9) And Enterobacter Cloacae Cs1 (sk4) For Plant Growth Promotion.
Inventors include Nikita Pradhan; Jasleen Kaur; Priya Mishra; Deepshikha Sharma; Durgesh Kumar Tripathi; and Amit Chandra Kharkwal.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present invention discloses a method for developing a novel bio NPK microbial consortium comprising Talaromyces albobiverticillius HNB9 and Enterobacter cloacae CS1 (SK4) for plant growth promotion. The method includes isolation, molecular identification, biosafety assessment, dual co-culture compatibility testing, optimization of co-culture conditions, and bioreactor-based upscaling to obtain a stable consortium having viable fungal spore density of about 5 × 107 spores mL?¹ and bacterial cell density of about 5 × 107 CFU mL?¹. The consortium enhances nitrogen fixation, phosphate solubilization, and potassium solubilization, resulting in improved plant biomass, chlorophyll content, and macronutrient uptake in wheat and fenugreek under controlled conditions. The invention provides an environmentally sustainable alternative to chemical fertilizers, improving soil fertility and crop productivity through synergistic microbial interaction.
