In a preceding paper, the fundamental conditions necessary in experiments employing the Warburg manometric technique to study the stimulatory effect of activated sludge on methane fermentation were discussed.In this paper, an attempt was made to isolate the stimulatory factors for gas production in methane fermentation from an aqueous extract of activated sludge. Fractionation of factors was carried out with Amberlite IR 120 resin, activated charcoal and paper chromatographic techniques. Results obtained showed the existence of at least three effective factors. The effects of activated sluge on methane fermentation seemed to be a complex one involving unidentified brownish colored substance as an essential factor and a group of amino acids and purine derivatives, such as adenine and hypoxanthine, as supplement factors.
