Abstract: A method for contamination control when growing yeasts is provided. Bacterial contamination is controlled by using urea as the primary nitrogen source while simultaneously limiting the amount of nickel available to contaminating bacteria. Bacteria require nickel as a cofactor for urease enzymes in order to use urea for growth while yeasts do not require nickel as a cofactor for any enzymes. Nickel is limited by using titanium in plate heat exchangers instead of stainless steel. Ethyl carbamate is limited by using a carbon/nitrogen ratio that consumes all urea during fermentation and by separating co-products after fermentation and before distillation. Yeast recycling is performed by using either single-step or two-step centrifugation, without acid washing. This method enables yeast recycling with sugarcane ethanol and sugar beet ethanol production. This method also enables yeast recycling with corn ethanol and grain ethanol production with coproduct recovery after fermentation and before distillation.

Abstract: The present invention relates to a transformed strain having ethanol production potential, constructed by introducing a foreign gene for ethanol production into a non-ethanol producing acetogen Eubacterium limosum and a method for producing ethanol, using the strain. According to the present invention, Eubacterium limosum which is a conventional acetogen lacking ethanol production potential is used to produce ethanol, which is a high value-added product, as a single product from carbon monoxide contained in waste gas.
