Pichia kudriavzevii WB17-1, a phytase-producing yeast isolated from duck excrement, was found to produce both cell-bound and extracellular phytases. To enhance extracellular phytase, P. kudriavzevii WB17-1 was subjected to induced mutation. Ethylmethane sulfonate (EMS)-induced mutation resulted in 2...
