Screening for growth and ethanol production
All the yeasts grew in the maintenance medium at 35 and
40◦C. Only two strains (IR2; IR2*) grew at 42◦C and no strain at
45◦C. The strains that grew at 40◦C in the maintenance medium
were incubated in the growth medium and the biomass and
ethanol production were evaluated at 24 h at 35, 40, 42 and
45◦C:
