Abstract:  A thermotolerant ethanol-fermenting yeast, Saccharomyces cerevisiae KNU5377, isolated from a sludge of a local industrial complex stream in Korea, was evaluated for its capability for lignocellulosic ethanol production from waste newsprint in high temperature. In this fermentation, most of dry-defibrated waste newspaper was first saccharified at 50 °C for 108 h using a commercial cellulase and, then with the last addition of dry-defibrated newsprints to the pre-saccharified broth, simultaneous saccharification and fermentation (SSF) of 1.0 L of reaction mixture was carried out at 40 °C, slowly being dropped from 50 °C, for further 72 h in a 5 L fermentor by inoculating the overnight culture of KNU5377. The maximum production of 8.4% (v/v) ethanol was obtained when 250 g (w/v)/L of dry-defibrated waste newspaper was used for ethanol production by SSF. These results suggest that S. cerevisiae KNU5377 is very useful for cellulose ethanol production by the SSF system.
