Development of biomass utilization technologies is one of the main area of researches in nowadays. Many biomass utilization process use enzymatic hydrolysis step. Monitoring of the efficiency of hydrolysis plays crucial role in the determination of optimum process time and contributes to achieve lower energy demand and better economy of technologies. Therefore, development of fast, but reliable and non-destructive measurement methods has high relevance not just for the science, but also for the practice. Dielectric measurements have great potential for these purposes, but there are very few experiences related their applicability for detection of conversion efficiency of enzymatic hydrolysis and fermentation processes. Therefore, our research has focused on the investigation of the applicability of dielectric measurements at the frequency range of 200-2400 MHz for the detection of the efficiency of sludge treatment processes, and monitoring the enzymatic hydrolysis of lignocellulosic biomass. Our results have shown that the cellulose degradation during the enzymatic hydrolysis of corn cob residue, and, as well as, the increment of organic matter solubility after different sludge disintegration methods can be monitored by the measurement of dielectric constant at the frequency range of 200-1000 MHz. The correlation between the indicators of biomass hydrolysis processes and dielectric parameters enables to develop on-line and real-time monitoring methods.
