Method for purifying reaction solution obtained by using microbial cell, immobilized microbial cell, or immobilized enzyme |
摘要 |
A method for purifying a reaction solution obtained by using a microbial cell, an immobilized microbial cell, or an immobilized enzyme as a catalyst in a water medium is disclosed. The method comprises repeatedly filtering the reaction solution to remove fine solid matter using a polyethylene porous hollow fiber membrane having a bubble point of from 1 to 20 kg/cm2, and repeatedly washing the hollow fiber membrane before it has been clogged to such an extent that a differential pressure thereof exceeds 3 kg/cm2. By this method, a filter membrane can be repeatedly regenerated at high efficiency and can stably be used for a long period of time.
