In the preceeding papers of this series, the authors have demonstrated the presence of stimuratory factors for methane fermentation in the aqueous extract of activated sludges and isolated a highly purified main effector, fraction G.This paper deals with the effect of fraction G on the rate of the glucose consumption and on that of the gas production and formation of volatile acids and their further destruction.The amount of glucose consumed is related to the amount of gas produced, but did not to volatile acids formed. Moreover, volatile acid, when used as a substrate, did not show a response to the gas production and exerted inhibition above the concentration of 2,000 ppm.From kinetic analysis of the experimental results, it appears likely that fraction G is involved as an accelerator of overall velocity of methane fermentation and raised the reaction rate.
