YEAST HAVING XYLOSE ASSIMILATION ABILITY AND ETHANOL PRODUCTION ABILITY

An object is to provide a thermotolerant yeast capable of assimilating xylose to produce ethanol or a mutant strain thereof and a method for producing ethanol by assimilation of xylose. There is used a yeast, Kluyveromyces marxianus strain No. 21 (accession number: NITE BP-01739), or a mutant strain...

More Information
Summary:An object is to provide a thermotolerant yeast capable of assimilating xylose to produce ethanol or a mutant strain thereof and a method for producing ethanol by assimilation of xylose. There is used a yeast, Kluyveromyces marxianus strain No. 21 (accession number: NITE BP-01739), or a mutant strain thereof that has xylose assimilation ability and ethanol production ability when cultured at 30° C. under aerobic conditions using a culture medium containing xylose as a sugar source. Also performed is a method for producing ethanol, comprising culturing the yeast or the mutant strain thereof under aerobic conditions using a culture medium containing xylose as a sugar source.
