Abstract
Experiments with a number of bacteria isolated from activated sludge have shown that flocculation is independent of the presence of poly-beta-hydroxybutyrate (PHB) in the cells. Several strains gave flocculent growth without any PHB detectable. Other strains, producing PHB in varying amounts, utilized this compound as an endogenous substrate, and after its disappearance the floc structure remained unchanged. The PHB content of various samples of activated sludge was found to be negligible.
