NOVEL PHYTASE AND PROCESS FOR THE PREPARATION THEREOF

摘要

PURPOSE: Provided is inexpensive phytases with low Michaelis constants (abbreviated hereinafter to Km) for phytic acid, which decompose phytic acid as anti-trophic factor contained in feed thereby improving the nutritive values of feed and simultaneously enabling efficient utilization of phosphate released by the decomposition CONSTITUTION: Provided is phytases having low Km values for phytic acid, a process for producing the phytases by using a microorganism having the ability to produce and accumulate the phytases and feed containing the phytases. According to the present invention, novel phytases decompose phytic acid as anti-trophic factor contained in feed thereby improving the nutritive values of feed and simultaneously enabling efficient utilization of phosphate released by said decomposition
