YEAST SACCHAROMYCES CEREVISIAE KK1 PRODUCING ETHANOL WITH HIGH YIELD AND THE METHOD OF ETHANOL FERMENTATION USING THE YEAST

摘要

PURPOSE: A fermentation method for producing ethanol of high concentration using yeast from various kinds of crops is provided to improve ethanol productivity and process. CONSTITUTION: A Saccharomyces cerevisiae KK1 strain(KACC 93077P) is able to produce ethanol of high concentration and high yield. A strain with excellent ethanol productivity is obtained by improving the strain by mutation and selecting. A method for producing ethanol of high purity and high yield comprises a non-streaming way and steaming way. The non-steaming way is performed by mixing grains and water in a ratio of 1:1.3, inoculating Saccharomyces cerevisiae KK1 to the mixture, adding Rhizopus sp. and sacchrifying at 26C.
