The rising demands for biofuels and other bio­based chemical products enlarge the demand of raw material feedstock. Lignocelluloses, especially from residual biomass like straw, have great potential to fit that gap. The processing of lignocelluloses by an enzymatic saccharification requires a set of pretreatment steps. Different kinds of pretreatment techniques are described in the literature. One mostly used, the diluted acid pretreatment with mineral acids, is a state of the art technique and used in...
