Abstract

The crude multienzyme extract produced by Fusarium oxysporum cultivated under submerged conditions in 20 L bioreactor using brewers spent grain and corn cobs in a ratio 2:1 as the carbon source was evaluated with regard to an efficient saccharification of hydrothermally treated wheat straw. Several factors concerning the obtained hydrolysis yield and reaction rate were investigated. The takeout of product sugars (in situ) was effective at reducing end-product inhibition and lead to a bioconversion about 80% of the theoretical. A kinetic model incorporating dynamic adsorption, enzymatic hydrolysis, and product inhibition was developed. The model predicted very satisfactorily the experimental data.
