Patent ID: 8257959

Claim:
An isolated non-recombinant Saccharomyces cerevisiae strain selected from the group consisting of: (a) strain NM04/41257; (b) a Saccharomyces cerevisiae strain having a growth rate using xylose as a sole carbon source that is about the same as that of strain NM04/41257; (c) strain NM04/41258; (d) a Saccharomyces cerevisiae strain having a growth rate using xylose as a sole carbon source that is about the same as that of strain NM04/41258; (e) strain NM05/45177; (f) a Saccharomyces cerevisiae strain having a growth rate using xylose as a sole carbon source that is about the same as that of strain NM05/45177; (g) NM05/45178; and (h) a Saccharomyces cerevisiae strain having a growth rate using xylose as a sole carbon source that is about the same as that of strain NM05/45178.
