Enhanced bio-ethanol production from cellulosic materials by semi-simultaneous saccharification and fermentation using high temperature resistant Saccharomyces cerevisiae TJ14

The capability of multi-stress-tolerant Saccharomyces cerevisiae diploid strain TJ14 for the production of cellulosic bio-ethanol by semi-simultaneous saccharification and fermentation (SSSF) technology was evaluated under high-temperature conditions. At 39°C, the TJ14 produced 45 g/l ethanol by SSSF of 100 g (w/v)/l cellulose – a significantly higher concentration than reported in prevailing literature.
