MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202411066593 A) filed by Amity University, Noida, Uttar Pradesh, on Sept. 3, 2024, for 'a bioreactor provided with a method for bioremediation of lead (pb) contamination in water using escherichia fergusonii strain u1.'
Inventor(s) include Akanksha Srivastava; Naveen Chandra Joshi; Navaneet Chautrvedi; Prem Chandra; Bhudev C Das; and Vaibhav Mishra.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a bioreactor system and process for the removal of lead (Pb) from wastewater using a Pb-resistant bacterium, Escherichia fergusonii strain U1. The strain was isolated from heavy metal-polluted soil and demonstrated high tolerance and Pb-removal efficiency under different pH and concentration conditions. In one aspect, the invention provides a process for culturing and employing Escherichia fergusonii strain U1 to sequester Pb ions from aqueous solutions through biosorption and bioaccumulation. In another aspect, the invention discloses a shake flask bioreactor system comprising porous sugarcane bagasse balls impregnated with immobilized Escherichia fergusonii strain U1 cells. Wastewater effluent from a primary treatment stage is introduced into the bioreactor, where the immobilized cells remove Pb ions during the secondary treatment stage. The treated effluent, with significantly reduced Pb concentration, is subsequently discharged for tertiary treatment. The system provides an efficient, cost-effective, and eco-friendly method for simultaneous removal of organic matter and heavy metals from industrial wastewater."
