  • Microbiological removal of bromine salts from fluid streams
    Patent number: 6755971
    Abstract: A process for the removal of undesirable bromine salts from fluid streams, especially waste and/or drinking water, comprising the step of exposing the fluid stream to a micro-organism which biochemically aids the reduction of the undesirable bromine salts, characterized in that the microorganisms belong to the group of pure and/or enrichment strains of bacteria grown on one or more of the following: perchlorate, chlorate, and bromate, or belong to bromate respiring bacteria.
    Type: Grant
    Filed: March 28, 2003
    Date of Patent: June 29, 2004
    Assignee: AKZO Nobel N.V.
    Inventors: Alexander Gerardus Maria Kroon, Cornelis Gijsbertus Van Ginkel

  • Process for the degradation of chlorite
    Patent number: 5891339
    Abstract: The present invention provides a process for the degradation of chlorite into chloride and oxygen with the aid of chlorite dismutase or chlorites dismutase-containing microorganisms. Virtually quantitative degradation of chlorite is obtained in the absence of reductors and under either aerobic or anaerobic conditions.
