In-situ viscometry during hydrolysis of lignocellulosic materials by single and cocktail enzymatic activities: from material impact to viscosity overshoot

Rheological characterization of lignocellulosic suspension is a fundamental research to overpass physical limitations during enzymatic hydrolysis. In this study, the rheological properties of lignocellulosic suspensions (filter paper - FP, paper pulp - PP and pretreated sugarcane bagasse - SCB) and their evolution during enzymatic hydrolysis were investigated by in-situ measurements. All tested suspensions behaved as shear thinning fluids and a critical concentration reflecting the change between diluted to semi-dilute regimes were identified.
