STUDIES ON SOME BIOCHEMICAL CHANGES DURING CITRIC ACID PRODUCTION IN A SYNTHETIC MEDIUM BY A MUTANT ASPERGILLUS NIGER AB1801
AbstractAn experimental study was carried out to examine the biochemical changes in the fermentation broth during citric acid production by a mutant Aspergillus niger AB1801. The production of citric acid was increased upto 8th day of fermentation, and then declined. pH decreased continuously, dry cell weight followed continuous increment pattern. Amino nitrogen and urea nitrogen decreased gradually, but ammonical nitrogen increased steadily.
