products as substrates. The results in the present study indicated that phytase production pattern varied with the substrate
type. The combination between corn cob and corn bran in the same ratio gave the highest enzyme activity. It is possible that
some of the constituents in corn cob and corn bran, particularly phytate and glucose, could be responsible for inducing phytase production from this isolate. Similar results were reported where the phytase production by Bacillus cereus ASUIA260
