dilute acid hydrolysis of cellulose

What is dilute acid hydrolysis?
Dilute acid hydrolysis is a process in which cellulose is hydrolyzed to glucose monosaccharide by using an inorganic acid such as sulfuric acid or hydrochloric acid as the catalyst, generally under a 10% (w/w) load. Dilute acid hydrolysis is the oldest and most mature method for the production of alcohol from lignocellulosic materials.
How is cellulose broken down?
The biomass has to be pre-treated, e.g. with a short, dilute acid hydrolysis step in which the structure of the cellulose is disrupted and the hemicellulose is broken down into fermentable sugars. The cellulose is then broken down by cellulases into cellobios which in turn is cleaved by β-glucosidase into glucose.
Does dilute acid hydrolysis pretreatment increase cellulose accessibility to enzymatic hydrolysis?
The dilute acid hydrolysis pretreatment allowed an increase of 5 fold to cardoon and 16 fold to rockrose in cellulose accessibility toward enzymatic hydrolysis. El Harchi, Kachkach, and El Mtili (2018) investigated the feasibility of bioethanol production from hydrolyzate of green seaweed Ulva rigida.
What is acid-catalyzed hydrolysis?
Acid-catalyzed hydrolysis has been employed for yielding free sugars from highly complex LCBs. Two types of acid hydrolysis process are commonly used: dilute and concentrated acid hydrolysis ( Dagnino, Chamorro, Romano, Felissia, & Area, 2013 ).
