Optimizing Biorefinery Efficiency: High-Solid, Low-Dosage Enzymatic Hydrolysis of Ethanol-Based Acid-Catalyzed Organosolv of Cynara Cardunculus

Short Introductive summary

Cynara cardunculus is a perennial non-food oilseed crop native of the Mediterranean region able to grow in marginal lands with a relatively low crop input and a large biomass productivity. Its stalks (CcS) are a residual lignocellulosic biomass commonly used as a fuel in combustion process. In this work, pretreatment of CcS with microwaved-assisted, acid-catalyzed, ethanol-based organosolv was used to produce a cellulose pulp that underwent a high-solid low-dosage enzymatic hydrolysis to valorize the saccharide content. Two different Experimental Designs based on Response Surface Methodology were applied to respectively check acid catalyst concentration, ethanol/water mixture concentration, and temperature in the organosolv process, and enzyme concentration, solid loading, and incubation time in the enzymatic hydrolysis, defining an optimal point for both processes.
