Abstract
In our present study, we wanted to investigate the applicability of dielectric properties measurement to monitor the progress of three distinct but connected subprocesses of lignocellulosic biomass utilization. These involved the enzymatic saccharification of corn-cob residues, followed by the bioethanol fermentation of the hydrolysates, and lastly, the anaerobic biogas co-digestion of industrial wastewater sludge and solid residues from the alcohol fermentation part. Our results revealed that a strong and established correlation can be found between the process indicators and the dielectric constant of the different fermentation media - namely, the absolute sugar concentration during the enzymatic hydrolysis, the ethanol concentration during the alcohol fermentation, and the biogas yield during the anaerobic codigestion. The relationship between these parameters can be described via linear functions, and the coefficient of correlation r varied between 0.97-0.99, while the R2 -value between 0.96-0.99.
