USE OF A NITROGEN- FREE PEROXYGEN- RELEASING COMPOUND TO REDUCE GROWTH OF CONTAMINANT MICROORGANISMS IN ETHANOL FERMENTATION.

摘要

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.
