Phytases hydrolyze phytates to liberate soluble and thus readily utilizable inorganic phosphate. Although phytases are produced by various groups of microbes, yeasts being simple eukaryotes and mostly non-pathogenic with proven probiotic benefits can serve as ideal candidates for phytase research. The full potential of yeast phytases has not, however, been exploited. This review focuses attention on the present status of knowledge on the production, characterization, molecular characteristics, and cloning and over-expression of yeast phytases. Several potential applications of the yeast phytases in feeds and foods, and in the synthesis of lower myo-inositol phosphates are also discussed.

酵母肌醇六磷酸酶：现状和未来展望。

植酸酶水解肌醇六磷酸释放出可溶的，因此易于利用的无机磷酸盐。尽管肌醇六磷酸酶是由各种微生物产生的，但是酵母是简单的真核生物，并且大多数具有非病原性，并具有公认的益生菌益处，可以作为肌醇六磷酸酶研究的理想候选者。但是，尚未开发出酵母植酸酶的全部潜力。这篇综述集中在酵母植酸酶的生产，表征，分子特征以及克隆和过表达方面的知识的现状。还讨论了酵母植酸酶在饲料和食品中以及在低级肌醇磷酸酯的合成中的几种潜在应用。
