MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541121558 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Dec. 4, 2025, for 'an eco-friendly novel approach to minimize the pollution load.'
Inventor(s) include Swethashree Rajendran; Ashmitha Kalairaj; Shrinidhi Sureshbabu; T. Senthilvelan; and Dr Ramya Mohan.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "This invention discloses a green nanobiocatalytic approach for the treatment of syntan-laden wastewater from leather processing industries. A laccase-functionalized titanium dioxide nanozyme (Lac@TiO2), synthesized using crude extracellular laccase derived from Penicillium chrysogenum, was developed for efficient degradation of phenolic (DI) and melamine-based (FB6) syntans. Under optimized conditions, the nanozyme achieved biodegradation efficiencies of up to 96% and 94%, respectively, while substantially lowering the chemical oxygen demand (COD) and total organic carbon (TOC) by more than 80% in both cases. Structural and compositional changes in syntans and detoxification of treated effluents were confirmed through advanced analytical techniques including UV-Vis spectroscopy, FTIR, UPLC, CHNS elemental analysis, and plant-based bioassays. This nanozyme has greater stability than crude laccase, can be reused up to 10 times, and is recyclable. This sustainable and cost-effective process is designed for seamless scalability, addressing the pressing environmental burden of recalcitrant organic pollutants from industrial leather effluents."
