Abstract

A new thermotolerant yeast strain was siolated, and its characteristics have been studied. The strain was identified and named Saccharomyces cerevisiae F38-1. This strain could grow not only at high temperature, but also in high concentrations of sugar and ethanol. S. cerevisiae F38-1 could grow in a medium containing 50% glucose. The isolate produced ethanol at 43$\circ$C, but didn't grow at 40$\circ$C in the presence of 8% ethanol. Fermentation studies showed that the isolate ferments 20% glucose to 9.8% (V/V) ethanol at 40$\circ$C in the presence of 0.2%, yeast extract.
