  • Control of contaminant microorganisms in fermentation processes with peroxygen-releasing compounds
    Patent number: 8759051
    Abstract: A method for controlling growth of contaminant microorganisms in a fermentation process using a nitrogen-free peroxygen-releasing compound. The method comprises adding the nitrogen-free peroxygen-releasing compound to one or more steps of a fermentation process. In this method, the a nitrogen-free peroxygen-releasing compound may be added to one or more components of a fermentation broth comprising inoculant, fermentable sugar and process water.
    Type: Grant

  • CONTROL OF CONTAMINANT MICROORGANISMS IN FERMENTATION PROCESSES WITH SYNERGISTIC FORMULATIONS CONTAINING PEROXIDE COMPOUND AND QUATERNARY AMMONIUM COMPOUND
    Publication number: 20120322125
    Abstract: A method for controlling growth of contaminant microorganisms in a fermentation process using a combination of (a) peroxide compound (PC) and (b) a quaternary ammonium compound (QAC). The method comprises adding PC and QAC to one or more steps of a fermentation process. In this method, the PC and QAC may be added to one or more components of a fermentation broth comprising inoculant, fermentable sugar and process water.

  • CONTROL OF CONTAMINANT MICROORGANISMS IN FERMENTATION PROCESSES WITH SYNERGISTIC FORMULATIONS CONTAINING STABILIZED CHLORINE DIOXIDE AND QUATERNARY AMMONIUM COMPOUND
    Publication number: 20120322124
    Abstract: A method for controlling growth of contaminant microorganisms in a fermentation process and in a fermentation system using a composition comprising (a) stabilized chlorine dioxide (SCD) and (b) a quaternary ammonium compound (QAC). The method comprises adding SCD and QAC to one or more steps of a fermentation process. In this method, the SCD and QAC may be added to one or more components of a fermentation broth comprising inoculant, fermentable sugar and process water.
