  • Microbiological desulfurization of sulfur containing gases
    Patent number: 6287873
    Abstract: A microbial consortium, ATCC 202177, is enriched to remove target sulfur compounds from gases in the presence of ammonia, cyanide, carbon monoxide, and other toxic gases and mixtures thereof. The ATCC 202177 consortium is cultured in an anaerobic or aerobic nutrient medium until enough cells of ATCC 202177 are recovered to remove the target sulfur species at a pressure ranging from 1 to 80 atmospheres.
    Type: Grant
    Filed: March 3, 1999
    Date of Patent: September 11, 2001
    Assignee: Arctech Inc.
    Inventors: Kailish C. Srivastava, Seema Garg, Daman S. Walia
