MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611107155 A) filed by Thapar Institute Of Engineering & Technology; and Nbcc India Ltd. on September 07, 2026, for Microbially Functionalized Banana Fiber For Enhancing The Mechanical Performance And Self- Healing Of Reinforced Concrete.
Inventors include Dr. Shweta Goyal; Dr. M. S Reddy; and Rohan Anand.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to a microbially functionalized banana fiber and a method for preparing the same. The invention utilizes natural banana fibers as a carrier for immobilizing viable bacterial cells through an adsorption-based process to obtain a dual-functional bio-fiber. The microbially functionalized banana fiber simultaneously provides crack-bridging reinforcement and promotes microbial-induced calcium carbonate precipitation (MICCP), enabling autonomous self-healing of cracks within the concrete matrix. The natural banana fibers exhibit enhanced bacterial adherence and viability, facilitating efficient calcium carbonate precipitation for crack sealing while improving the mechanical performance, crack resistance, and durability of reinforced concrete. The developed bio-functional fiber enhances the service life of reinforced concrete structures while supporting sustainable and durable construction practices through an integrated reinforcement and self-healing mechanism.
