Breeding of yeast strains able to grow at 42 degrees C.
Saccharomyces cerevisiae strain 2-39/10A is able to ferment alcohol at 42 degrees C. The ability of various yeast strains, including 2-39/10A, to grow at high temperatures was compared. The strain 2-39/10A was able to grow at 42 degrees C and the high temperature growth was found to be governed by more than one gene. The yeast strains that can grow at 42 degrees C were bred by crossing the haploid strains, which are inherently unable to grow at high temperatures.
