• To maintain good conditions in a thermophilic methane bioreactor treating methanol as the main substrate, microbial enxyme activity in the reactor was investigated. In a preliminary study, seven enzymes were tested for their suitability as indicators using an acid-former, 22a originating from a digester with low efficiency, Methanosarcina sp.(CHTI-55)and Desulfotomaculum nigrificans(Delft 74). Among the tested strains, the activities of seven enzymes were the highest in 22a. Acidic phosphatase(ACP), glutamic-pyruvic transaminase(GTP)and α-amylase(AMY)were chosen as hopeful indicators for lab-scale tests and their activities were measured at the optimum temperature of 55℃. In the lab-scale test, reactor failure was induced by nitrogen deficiency or addition of dimethyl disulfide(DMDS)as an inhibitor. ACP, GPT and AMY outperformed the conventional parameters as indicators of any instability in the process.
