In the preceding paper, it was shown that methane fermentation proceeds under an appropriate and stable redox potential (ORP), -330mV, which is correlated not only with rate of gas production but also with the length of the lag phase of gas production. It was also observed that the addition of an extract of activated sludge exerts a remarkable effect on the reduction of the lag time and stabilizing of ORP.In this experiments were undertaken for employing the Warburg manometric technique to study the stimulatory effect of activated sludge on methame fermentation, excepting both improvement of accuracy and shortening of the time of the experiment.From the results of the experiment concerning the amount of cell suspension, concentration of glucose used as a substrate and the effect of addition of cysteine or exchange of air with N_2 or CO_2 for maintenance of anaerobic condition, it was concluded that the conventional manometric method is useful for the investigation of methane fermentation.
