植酸酶作为饲料及食品添加剂正在受到广泛关注。目前国内外生产植酸酶所用酶源菌株为霉菌或基因重组菌,且均为胞外酶。本研究采用天然酵母菌作为酶源菌株生产出新型酵母细胞表面酶——植酸酶。用天然菌生产的植酸酶产品附加值高,属于新型绿色饲料和食品添加剂。随着国家强制要求在饲料中添加植酸酶取代磷酸氢钙,植酸酶的市场会越来越广阔。文章介绍了植酸酶的特性、生产工艺、应用效果。
Phytase is gaining widespread attention as a feed and food additive. At present, the enzyme source strains used for producing phytase are molds or gene-modified bacteria, and all are extracellular enzymes. In this study, natural yeast as an enzyme source strains to produce a new yeast cell surface enzyme - phytase. Phytase products produced with natural bacteria have high added value and belong to the new green feed and food additives. As the country mandates the addition of phytase to feed instead of dicalcium phosphate, the phytase market will become more and more widespread. The article describes the characteristics of phytase, production technology, application results.
