title: Phytase enzymology, applications, and biotechnology.
abstract: Phytases are phosphohydrolases that initiate the step-wise removal of phosphate from phytate. These enzymes have been widely used in animal feeding to improve phosphorus nutrition and to reduce phosphorus pollution of animal waste. The potential of phytases in improving human nutrition of essential trace minerals in plant-derived foods is being explored. This review covers the basic biochemistry and application of phytases, and emphasizes the emerging biotechnology used for developing new effective phytases with improved properties.
