Thermomechanical pulping (TMP) wastewater was tested for the feasibility of augmenting readily biodegradable organics for enhanced microbial hydrolysis by thermophilic acidogens. A biochemical methane potential test showed approximately 13±1 % of the chemical oxygen demand was anaerobically biodegradable. Three glucose concentrations set up in a ratio of 1:3:6, 5, 15, and 30g/l, were tested to induce the production of short-chain organic acids and ethanol. Compared to the control with no glucose addition, more than six times of the fragmentation of lignocellulosics in the wastewater was achieved.
