MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641009538 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Jan. 30, for 'a bio nano hybrid immobilized matrix for textile dye remediation and process for synthesising the same.'
Inventor(s) include Priyanka Mary Sebastian; and Dr. K. V. Bhaskara Rao.
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: "The present invention relates to a bio nano hybrid immobilized matrix and a process for remediation of textile dye effluents are disclosed. the hybrid matrix comprises dye-degrading bacterial cells of Enterobacter cloacae, biogenically synthesized zinc oxide (ZnO) nanoparticles, and a calcium alginate polymer matrix, wherein the bacterial cells and nanoparticles are co-immobilized to form a stable and reusable composite system. the bacterial cells enzymatically degrade azo dye bonds through azoreductase activity, while the ZnO nanoparticles photocatalytically oxidize dye intermediates, enabling synergistic degradation of textile dyes. the polymer matrix prevents nanoparticle aggregation and protects bacterial cells from environmental stress, thereby enhancing operational stability and reusability. the process includes isolating and culturing the dye-degrading bacterium, biogenically synthesizing ZnO nanoparticles using a cell-free bacterial supernatant, preparing a sodium alginate immobilization medium, co-immobilizing the bacterial cells and nanoparticles, and cross-linking with a divalent cation to form stable bio nano hybrid beads. the system provides an efficient, eco-friendly, and cost-effective approach for treatment of dye-contaminated industrial wastewater to 6."
