MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541055276 A) filed by Prabhi Actus Innovations (OPC) Private Limited, Mandya, Karnataka, on June 8, 2025, for 'device for selective removal and in-situ treatment of fungal contamination in tissue culture vessels.'
Inventor(s) include Dr. Sujit Kumar Yadav; and Srijan Yadav.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides an integrated tissue culture contamination control device that combines selective removal of contaminated media with targeted fungicidal treatment to achieve superior contamination elimination while preserving valuable uncontaminated culture material. The device comprises a cylindrical body (100) housing a precision elution mechanism (110) with flexible extraction tube (170) operating at controlled negative pressure, and a targeted spray system (130) with precision nozzle (160) for localized fungicide application. An integrated control valve (180) coordinates sequential operation to achieve unexpected synergistic effects, eliminating 95% of fungal contamination while preserving 70-85% of uncontaminated culture. The device addresses critical limitations of conventional disposal methods, reducing material waste by 60-80% and operational costs by 45-60% while maintaining culture viability above 90%. Applications include plant propagation, pharmaceutical research, and biotechnology laboratories where contamination control is essential for maintaining culture integrity and operational efficiency."
