  • Patent number: 9926576
    Abstract: A fermentation process for the production of ethanol from natural sources, such as corn, comprising introducing a fermentable sugar, an inoculant, and a stabilized chlorine dioxide into a fermentation system is disclosed. The stabilized chlorine dioxide is added preventatively to the fermentation system, at concentrations in the fermentation system of acetic acid no greater than 0.30% (weight/volume) and lactic acid no greater than 0.60% (weight/volume). The stabilized chlorine dioxide is added in an amount effective to substantially prevent growth of bacteria.
    Type: Grant

  • Patent number: 9504710
    Abstract: A process to preserve a carbohydrate feedstock against contaminant microorganisms comprises contacting the carbohydrate feedstock with a stabilized chlorine dioxide at a pH of at least 2.6. The carbohydrate feedstock preferably comprises a naturally-occurring carbohydrate, particularly a carbohydrate having a reducing end group. The process is particularly suitable to treat feedstocks used in biorefining processes, such as in ethanol fermentation.

  • 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.

  • Publication number: 20070281167
    Abstract: A method to improve cleanability of surfaces comprises applying a coating composition to a surface, wherein the composition comprises (a) a cross-linkable fluorotelomer comprising repeat units derived from a fluoroalkene; (b) a moisture-curable silicone; (c) a catalyst; and (d) a solvent to a surface, wherein the solvent is present in an amount such that the coating composition has a VOC content of not greater than 350 g VOC per liter of the composition; and curing the composition.
