Isolation and Chracterisation of phytase by Aureobasidium pullulans

Phytate, the major source of phosphorus in seeds, exists as a complex with different metal ions. The phytase production was stimulated by phytate in the medium used andAureobasidium pullulans showing phytase activity was isolated. the phytase exhibited high stability at temperatures up to 50°C.The maximum production of phytase (108 U/ml) occurred in a medium containing sodium phytaste. The phytase has an optimum pH of 5.5, and an optimum temperature of 50°C.
