【 摘 要 】

Phytase is one of the enzymes belonging to the group phosphatase, which is capable of hydrolyzing the phytic compounds in the form of myo-inositol (1.2.3.4.5.6) into myo-inositol phosphatase and organic phosphate. In the digestive tract of non-ruminant livestock (poultry) and fish, there are no phytase enzymes. This causes the content of the rice bran phytate compounds to be difficult to digest because of the strong chelating properties. Restrictions on the use of rice bran in the fish's diet are because of the fiber content and the high level of phytic acid. One alternative to reduce the phytate content of the feed is to use the phytase enzyme, which is expected to hydrolyze the phytic acid (myo-inositol 1.2.3.4.5.6) in the rice bran orthophosphate in organic produce. All of the minerals, such as P and Ca, are important minerals to release and it is used for the growth of both layers and fish. The result showed that: 1. The scanning Elektron Microscope (SEM) analysis of the surface with the addition of rice bran phytase enzymes caused the bond breaking force with the inositol phosphate acid groups. These showed changes in the structure of the phytic irregular bond and 2. The addition of the phytase enzymes to degrade phytic acid increases the availability of minerals such as phosphorus and calcium and crude protein, and decreases the crude fiber in the rice bran.
