MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641096669 A) filed by Vellore Institute Of Technology on August 10, 2026, for A Method For Integrated Microbial Remediation Of Used Engine Oil Under Static Conditions.
Inventors include Krishnan Kannabiran; and Sreenidhi Y.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present disclosure proposes a method for integrated remediation of used engine oil using a defined co-culture of Gordonia amicalis VITSYK1 and Stutzerimonas stutzeri VITSYK4 under static conditions, enabling simultaneous petroleum-hydrocarbon degradation and heavy-metal reduction without mechanical agitation, thereby providing a low-energy, single-stage treatment process. The method comprises providing Bushnell Haas broth containing used engine oil at a concentration ranging from 1% to 8% by volume, preparing the defined microbial co-culture in a culture-volume ratio of 6:4, inoculating the broth at a total inoculum concentration ranging from 1% to 4% by volume, and incubating the inoculated broth at 27 °C to 42 °C and pH 6.0 to 8.0. During the same incubation, aliphatic and aromatic petroleum hydrocarbons are biodegraded, and measured concentrations of copper, iron, manganese, nickel, zinc, chromium, cadmium, and arsenic are reduced, thereby providing a single-stage remediation process.
