Inhibitors

Inhibitors	Comment	Organism	Structure
Cu2+	effect on the ability of phytase to hydrolyze phytate phosphorus is dependent on pH. At pH 2.5 (gastric pH), no inhibition is noted among the treatments (copper citrate, copper chloride, copper lysinate, cupper sulfate, tribasic copper chloride) except that the addition of 250 and 500 mg Cu/kg diet from copper chloride and 500 mg Cu/kg from copper sulfate slightly inhibits phytate phosphorus hydrolysis. When pH is increased to 5.5-6.5 (small intestinal digesta) phytate phosphorus hydrolysis is greatly inhibited	Aspergillus niger
