TL;DR
The simultaneous one-step saccharification of alkali-treated newspaper using T. reesei cellulase and fermentation to ethanol by Saccharomyces cerevisiae gave increased ethanol with increased substrate up to 5% paper, the maximum used.
Abstract
Cellulase produced by Trichoderma reesei QM 9414 exhibited higher filter paper enzyme (FPase) and endo-,1,4-glucanase (Cx) activities when grown on 1% (w/v) microcrystalline cellulose powder than when grown on untreated or alkali-treated newspaper substrates. However, the cellulase produced on alkali-treated newspaper substrate exhibited a maximum degree of saccharification of alkali-treated newspaper during 72 h incubation compared to the cellulases obtained on other cellulosic substrates. The simultaneous one-step saccharification of alkali-treated newspaper using T. reesei cellulase and fermentation to ethanol by Saccharomyces cerevisiae gave increased ethanol with increased substrate up to 5% paper, the maximum used.
