Abstract excerpt

Phytase is widely used as a feed additive in industry. It is important to investigate the thermal stability, optimal pH and temperature and protease resistance of phytases in application. We introduced random mutations in a protease-resistance phytase gene of Penicillium sp. using Mn²+-dITP rando...
