PROCESS FOR THE FERMENTATIVE PRODUCTION OF CITRIC ACID FROM CARBOHYDRATES |
摘要 |
Proposed is a process for the fermentative production of citric acid from carbohydrates by means of a microorganism of the species Aspergillus niger in a substrate containing zinc ions and hexacyanoferrate ions wherein carbohydrates not prepurified are employed and the Zn content of the substrate is adjusted to 30 to 250 ppm and the hexacyanoferrate content of the substrate is adjusted to 100 to 500 ppm.
