CITRIC ACID FERMENTATION MICROORGANISM-IMMOBILIZED CARRIER, METHOD FOR PRODUCING THE SAME AND METHOD FOR PRODUCING CITRIC ACID

摘要

PROBLEM TO BE SOLVED: To obtain a citric acid fermentation microorganism-immobilized carrier, which produces citric acid in high production efficiency and to provide a method for producing citric acid. SOLUTION: The citric acid fermentation microorganism-immobilized carrier is obtained by supporting a citric acid fermentation microorganism on a polyvinyl alcohol-based porous gel. The method for producing citric acid comprises bringing water containing a saccharide into contact with the citric acid fermentation microorganism-immobilized carrier. An Aspergillus strain is preferably used as the citric acid fermentation microorganism. COPYRIGHT: (C)2008,JPO&INPIT
