Lignocellulosic biomasses (LCB) are appealing raw materials than can yield various amounts of hemicellulose, cellulose, lignin or protein but their fractionation into compounds of interest can be challenging, due to the strong entanglement of those fractions. More specifically, cellulose shows a higher resistance to extraction and degradation (hydrolysis) treatments due to its crystalline/semi-crystalline nature.
