Probiotic phytases are enzymes produced by probiotic microorganisms. These enzymes have the ability to hydrolyze phytic acid (myo-inositol hexakisphosphate), a form of phosphorus that is indigestible for many animals, including humans. By breaking down phytic acid, probiotic phytases release inorganic phosphate, which can then be absorbed by the digestive system. This process enhances the nutritional value of food and feed, making essential minerals more bioavailable.
