Abstract

Effect of the mechanical activation of rice husk on the progress of subsequent enzymatic hydrolysis was studied. It was established that mechanical treatment promotes an increase in specific surface area, destruction of the silica shell coating lignocellulose, and substantial amorphization of the crystal regions of cellulose. As a result, the degree of conversion of polymer carbohydrates into soluble saccharides increases practically by a factor of 13. So, mechanoenzymatic treatment of rice husk allows one to obtain carbohydrate-containing intermediate product that may be used for further microbiological processing.
