Four ethanologenic ethanol-tolerant yeast strains, Saccharomyces cerevisiae (ATKU132), Saccharomycodes ludwigii (ATKU47), and Issa- tchenkia orientalis (ATKU5-60 and ATKU5-70), were isolated by an enrichment technique in yeast extract peptone dextrose (YPD) medium supplemented with 10% (v/v) ethanol at 30°C. Among non-Saccharomyces yeasts, Sd. ludwigii ATKU47 exhibited the highest ethanoltolerance and ethanol production, which was similar to S. cerevisiae ATKU132. The maximum range of ethanol concentrations produced at 37°C by S. cerevisiae ATKU132 and Sd. ludwigii ATKU47 from an initial D-glucose concentration of 20% (w/v) and 28% (w/v) sugarcane molasses were 9.46–9.82% (w/v) and 8.07–8.32% (w/v), respectively.
