- Phytase is an enzyme that can break down the undigestible phytic acid (phytate) part found in grains and oil seeds and thus release digestible phosphorus, calcium and other nutrients. The enzyme phytase is normally produced (endogenous phytase)in ruminants.
- The pH optimum of phytases vary from 2.2 to 8. Most microbial phytases, especially those of fungal orgin, have a pH optimum between 4.5 and 5.6. In contrast to most fungal phytases, A.fumigatus phytase has a broad pH optimum; at least 80% of the maximal activity is observed at pH values between 4.0 and 7.3. Some bacterial phytases, especially those from Bacillus, have a pH optimum at 6.5 - 7.5. The pH optima of plant seed phytases range from 4.0 to 7.5, most having an optimum between 4.0 and 5.6. The temperature optima of phytases vary from 45 to 77oC.
- Phytate also reduces the digestibility of proteins, starch and lipids; inhibits enzymes such as a-amylase, trypsin, tyrosinase, etc. This is due to the chelating property of the substrate with the multivalent cations such as Zn2+, Fe2+, Ca2+, Mg2. Thus the presence of phytic acid in animal feeds is generally undesirable. Improved utilization of phosphorus present in phytate by animals can be met by supplementing phytase to the animal feed.
-
The industrial enzyme market is divided into three application segments: technical enzymes, food enzymes, and animal feed enzymes. The growth of animal feed enzymes is somewhat higher, expected to be close to 4% AAGR, helped in large part by increased use of phytase enzyme to fight phosphate pollution.
