Lignocellulose HydrolysisLignocellulosic biomass, primarily comprised of cellulose, hemicellulose, and lignin, is an abundant and renewable resource that holds great promise as a source of biofuels and renewable biobased chemicals and biomaterials. Lignocellulosic biomass can be processed in a number of ways, one is through the hydrolysis of the structural polysaccharides (cellulose and hemicellulose) into their constituent sugars, a reaction commonly facilitated by acid or enzymes, followed by the fermentation of these sugars by yeast or other microorganisms.
Enzymatic HydrolysisIn enzymatic hydrolysis cellulases and hemicellulases play a critical role, working synergistically to cleave the glycosidic linkages in cellulose and hemicellulose, respectively. However, depending on the type of pretreatment process involved, hydrolysis of hemicellulose may not be necessary, since it may have already taken place in the pretreatment leading to the hemicellulose sugars being in the liquid output of the pretreatment with the solid residue mostly containing cellulose (plus lignin, again dependent on the type of pretreatment).
CBP ProcessConsolidated bioprocessing (CBP), also known as direct microbial conversion, is a conceptual approach for integrated, one-reactor, biological conversion of lignocellulosic biomass to biofuels and biobased chemicals. By integrating enzyme production, saccharification (hydrolysis), and fermentation into a single step, CBP aims to simplify the process and reduce costs associated with biomass conversion.
