Bioethanol from oilseed rape straw hydrolysate using free and immobilised cells of Saccharomyces cerevisiae.

Study of bioethanol yield from oilseed rape straw.

Year of Publication2011

Oilseed rape (OSR) straw can serve as a low-cost feedstock for bioethanol production. Glucose and other fermentable sugars were extracted from OSR straw using sulfuric acid pre-treatment and enzymatic hydrolysis. Batch fermentation of enzymatic hydrolysate with Saccharomyces cerevisiae immobilised in Lentikat® was found to be superior to free cells in terms of bioethanol yield. The maximum bioethanol concentration from free and immobilised cells was 6.73 and 9.45 g.l-1, respectively, with corresponding yields of 0.41and 0.49 g bioethanol.
