The effect of incubation period, different carbon and nitrogen sources on the production of the extracellular polysaccharide pullulan by Aureobasidium pullulansNRRL58560 was examined. The results showed that the maximum production of pullulan was obtained 13.76 after 96 hours of incubation. Sucrose as a carbon source gave the highest production of pullulan 31.92 g/l while the highest biomass was obtained when starch was used as a carbon source 16.30 g/l. The amino acid glycine as a nitrogen source gave the highest production of pullulan 34.61 g/l and the highest production of biomass 14.49 g/l was obtained when ammonium chloride was used.
