Abstract
Kinetics of phytate hydrolysis by Aspergillus niger phytase and correlation between the amount of released phosphate and creation of lower myo-inositol phosphates were investigated. Phytase was able to hydrolyze myo-inositol hexakis-, pentakis-, tetrakis-, and trisphosphates. Finally, about 56% of total phosphate were released and myo-inositol bisphosphate was detected as the end-product.
摘要
研究了黑曲霉植酸酶水解植酸的动力学以及释放的磷酸盐量与低肌醇磷酸酯生成之间的相关性。植酸酶能够水解肌醇六磷酸、五磷酸、四磷酸和三磷酸。最终，约56%的总磷酸盐被释放出来，且检测到肌醇二磷酸为终产物。
