An artificial sewage which contained small amounts of organic acids, such as acetic acid or lactic acid stimulated filamentous bulking of normal sewage activated sludge as well as glucose-containing artificial sewage. When these artificial sewages were added continously to the sewage activated sludge at the concentrations of organic acid of more than 80mg/l, the sludge was bulked after 4-6 days cultivation. Polysaccharide accumulation were observed neither in bulked nor non-bulked sludges. This indicated that the filamentous bulking of activated sludge was not necessarily dependent to the accumulation of plysaccharides. Potentiality of lactic acid consumption rate by the activated sludge increased simultaneously with the increment of its SVI after the cultivation.
