  • Polyploid baker's yeasts having a low temperature inactivation property
    Patent number: 5399492
    Abstract: Polyploid yeasts having an lti property are obtained by sporulating a starting polyploid strain of Saccharomyces cerevisiae, selecting at least one segregant having an lti property, backcrossing the selected segregant at least once with another segregant having an opposite mating type, selecting at least two backcross segregants having an lti property and opposite mating types, crossing the selected backcross segregants at least once, and selecting a polyploid strain having a growth potential, an lti property, and an ability to raise a dough.
