Time course of cellulase activity and biogas production of the microbial community collected from the steady-state bioreactor after washing, change of medium, transfer to batch bottles and cellulase induction with cellulose. The cellulase activity presented represents the final fluorescence reading after 120Â min incubation with the fluorogenic substrate. Induction was terminated on day 5 to collect the induced enzyme solution (IES)
