Modelling real-time simultaneous saccharification and fermentation of lignocellulosic biomass and organic acid accumulation using dielectric spectroscopy

► Dielectric spectroscopy for monitoring enzyme hydrolysis of lignocellulose on-line. ► Influence of conductivity on the capacitance of grass fibre modelled. ► Enzyme hydrolysis of grass fibre causes exponential decay of capacitance. ► Influence of media conductivity on capacitance resolved with the model Cfit in SSF.
