Ethanol production from steam pretreated sugarcane bagasse via simultaneous saccharification and fermentation (SSF) using cellulase and b.glucosidase enzymes
(2008) p.1-8- Abstract
- Cellulosic ethanol was produced via simultaneous enzymatic hydrolysis and fermentation of steam pretreated sugarcane bagasse. Sugarcane bagasse underwent steam pretreatments at Log Ro 3.05-4.09, under catalysed (SO2 2% and H2SO4 0.25%) and uncatalysed conditions. Digestibilities of the steam pretreated bagasse were assessed via enzymatic hydrolysis using cellulase (Celluclast 1.5L) and B-glucosidase (Novozym 188) enzyme formulations at 2% WIS, 40 ºC, pH 4.8, 72h under continuous stirring (200 rpm). SO2-catalysed steam pretreated bagasses produced at moderate severities (180 or 190 ºC, 5 minutes) presented digestibilities up to 82%. Hemicellulose removal influenced pretreatment efficiency rather than delignification. SO2-steam pretreated... (More)

Hemicellulose removal influenced pretreatment efficiency rather than delignification. SO2-steam pretreated bagasses were processed by SSF (simultaneous saccharification and fermentation) at 5% WIS loading. Yields of 0.40-0.41 g ethanol/g glucose (approx. 80% of the theoretical) and high selectivity through ethyl alcohol were obtained for all investigated conditions, leading to a potential production of 230 L ethanol/ ton dry bagasse.
