Detection of the efficiency of enzymatic hydrolysis and fermentation processes by dielectric measurement

Abstract

: In our work the efficiency of enzymatic degradation of cellulosic biomass was investigated by conventional analytical methods and dielectric measurements. Our results show, that the dielectric measurements proved to be efficient and rapid method to detect the chemical and physicochemical change of biomass during the enzymatic hydrolysis of cellulose. Because of molecular weight decreasing, and the increasing of the concentration of polar and ionic components, the polarization ability of the system has been changed, what manifested in the change of dielectric parameters. Furthermore, dielectric measurements were suitable to detect the efficiency of biomass pre-treatment, as well.
