Descrição: Fuel ethanol is one of the most important alternative fuels used as a substitute for fossil fuel. Lignocellulose is the most abundant biomass resource for the production of fuel ethanol. However, the hydrolysis of lignocellulose requires high enzyme loading. In order to strengthen the process of enzyme hydrolysis of lignocellulose, surfactant-polyethylene glycol (PEG) was applied to the catalysis of lignocellulose into fermentable sugars. The effect of PEG on both the enzymatic hydrolysis and adsorption of cellulose were investigated. The addition of surfactant obviously facilitated enzymatic hydrolysis. In particular, upon addition of PEG4000, the enzyme catalytic efficiency increased by 51.06%. Meanwhile, the adsorption quantity of cellulase decreased by 11.25%. In addition, the mechanism of the effect of PEG on enzymatic hydrolysis and cellulase adsorption is discussed.
