  • 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.

  • Microbiological degradation of alkylene amine acetates
    Patent number: 5965024
    Abstract: The microbiological degradation of alkylene amine acetates under alkaline conditions using microorganisms present in activated sludge is achieved by contacting the alkylene amine acetate-containing waste, at a pH of about 9 or less, with activated sludge containing a wide range of microorganisms, in the absence of carrier materials.
