Thermostable fusant, Kluyveromyces marxianus CHY1612, was obtained by protoplast fusion between high ethanol fermentative Saccharomyces cerevisiae CHY1012 and thermostable Kluyveromyces marxianus CHY1703. AFEX pretreated barley straw at 150°C for 90 min was used in a simultaneous saccharification and fermentation (SSF) process using thermotolerant CHY1612. The SSF of 16% pretreated barley straw at 43°C gave a saccharification ratio of 90.5%, a final ethanol concentration of 38.5 g/L, and a theoretical yield of 91.2%.
These results show that K. marxianus CHY1612 has potential for efficient lignocellulosic ethanol production through simultaneous saccharification and fermentation with further improvement of its fermentability.
