Several process issues will be deepened: cellulase enzyme sy stems and hydrolysis mechanisms of cellulose; commercial mixtures; currents limits in the cellulose hydrolysis; innovative bioprocesses and improved biocatalysts 2 Structure of lignocellulose biomass |
Can acid hydrolysis convert lignocellulosic feedstock to monomer sugars?
The use of acid hydrolysis for the conversion of lignocellulosic feedstock to monomer sugarsis a process that has been studied for the last 100 years. Generally, there are two types of acid hydrolysis: dilute and concentrated, each having unique properties and effects on biomass, and each having advantages and disadvantages in terms of economics.
Which acid breaks down cellulose and hemicellulose polymers in lignocellulosic biomass?
1.1. Dilute acid hydrolysis Dilute or concentrated acids break down the cellulose and hemicellulose polymers in lignocellulosic biomass to form individual sugar molecules which can be fermented into ethanol . It is important to note that hemicellulose is more easily hydrolysed than cellulose .
How is lignocellulosic biomass decrystallized?
The decrystallization or hydrolysis of lignocellulosic biomass is usually carried out either with concentrated solutions at moderate temperature or with dilute solutions at high temperatures.
Can dilute acid hydrolysis improve lignocellulosic biomass pretreatment?
Currently, dilute acid hydrolysis is one of the most promising methods of lignocellulosic biomass pretreatment. It shows major improvements in hemicelluloses and cellulose hydrolysis for better enzymatic reaction rates, with comparatively higher sugar recoveries than other pretreatments.
