Other Notes
One unit will liberate 1.0 μmole of inorganic phosphorus from 1.5 mM phytate per min at pH 5.15 at 55 °C.
Analysis Note
Crude
Application
Phytase has been used in a study to quantify the number of feedstuffs showing significant phytase activity. It has also been used in a study to investigate the effect of adjusting the pH to 5.0 (optimum for wheat phytase) during whole wheat bread making on phytase activity.
Biochem/physiol Actions
Wheat phytase can degrade inositol phosphate-6 and 5 at a pH of 4 and 5.
General description
Phytase catalyzes the hydrolysis of phytic acid to inositol and free orthophosphate.

Phytic acid of soy meal (SM) could influence protein and important mineral digestion of monogastric animals. Aspergillus oryzae (ATCC 9362) solid-state fermentation was applied to degrade phytic acid in SM. Two-stage temperature fermentation protocol was investigated to increase the degradation

Phytases have been widely used as animal feed supplements to increase the availability of digestible phosphorus, especially in monogastric animals fed cereal grains. The present study describes the identification of a full-length phytase gene of Prevotella species present in Mehsani

Many plant-based systems have been developed as bioreactors to produce recombinant proteins. The choice of system for large-scale production depends on its intrinsic expression efficiency and its propensity for scale-up, post-harvest storage and downstream processing. Factors that must be considered

Zinc (Zn) is essential for swine and poultry and native Zn concentrations in feedstuffs are too low to meet their Zn requirement. Dietary Zn bioavailability is affected by phytate, phytase and Zn supplemented in organic form is considered as more
