Potential of Phytase Enzymes as Biocatalysts for Improved Nutritional Value of Rice Bran for Broiler Feed

Phytase is one of the enzymes belonging to the group phosphatase capable of hydrolyzing phytic compounds in the form of myo- inositol (1.2.3.4.5.6) hexsa into myo-inositol phosphatase and organic phosphate . In the digestive tract nonruminant livestock (poultry) there is no phytaseenzymes , it causes the content of the rice bran phytate compounds are difficult to digest because of the strong chelating properties , so it wasted phytate with feces. Restrictions on the use of rice bran in the diet because the fiber content and high phyticacid . One alternative to reduce the phytate content of the feed is to use phytase enzyme produced from Actinobacillus sp and Bacillus pumilus) is expected to hydrolyze phytic acid ( myo-inositol 1.2.3.4.5.6- hexakisphosphate) for rice bran orthophosphate in organic produce and a series of lower phosphoric into myo -inositol -free , so all minerals such as P, Cawhich is an important mineral to be released and used for the growth of broiler chickens. The results obtained adding the enzyme phytase can improve the nutritional quality of rice bran content is increasing crude protein, crude fiber and increasing decline in the availability of minerals calcium and phosphorus.
