We reported the optimum amount of PHB accumulated by Alcaligenes faecalis during its 24 h growth under nitrogen defi cient conditions. After 24 h incubation decrease in the amount of PHB was recorded. Hypochlorite digestion of biomass of organism followed by extraction with a solvent system consisting of 1:1 mixture of ethanol and acetone resulted in effi cient recovery of PHB vis-à-vis earlier methods. This solvent system gave a high recovery yield, i.e. 5.6 gL -1 vis-à-vis earlier reported yield, 1.34 gL -1 (by same method), 0.63 gL -1 (by chloroform extraction method) and 1.1 gL -1 (by dispersion method).
