To obtain basec information on the anaerobic digestion of cellulose, the digestion kinetics of cellulose was studied in continuous culture using an artificial wastewter containing cellulose powder. Cellulose was found to undergo relatively slow degradation, which seemed to be the rate-determining step in the overall digestion process. The maximum specific growth rate (μ_m) and the saturation constant (K_s) obtained form continuous cultures were 0.213 (1/day) and 554 (mg cellulose/l) for the acid-former, and 0.528 (1/day) and 261 (mg volatile fatty acid/l) for the methane-former, respectively. The concentrations of the acid-and methane-formers in the reactor were also estimated using these kinetic coefficients.
