The article offers information on a research that studies the effect of conduction deacetylation before dilute acid pretreatment for the production of ethanol from lignocellulosic biomass. It is mentioned that dilute acid pretreatment is an effective of producing of ethanol and during the process, xylan undergoes depolymerization forming soluble xylose monomers and oligomers. Also, the formation of xylose monomers depends upon cleavage of the xylosidic bonds, and cleavage of covalently bonded acetyl ester groups. Additionally, it is informed that acetyl groups can cause biomass recalcitrance and hydrolyzate toxicity. It is observed that deactelyation increases glucose and xylose yields during pretreatment and enzymatic hydrolysis.
