Strains of Saccharomyces spp. from tropical substrates tolerated tempe
ratures up to 40 degrees C, sucrose concentrations up to 50% (w/v) and
ethanol concentrations up to 20 g/L in fermentation conditions. Strai
n TD200 tolerated 20 g/l of ethanol. The ethanol produced by strain DR
1459 was comparable to that of industrial strain HTYM-81. These strain
s have potential use for the production of fuel alcohol.
