Abstract:
Aspergillus niger produces citric acid during surface fermentation on inulin, a reserve carbohydrate of plant tubers. Citric acid yields can be improved by airflow over the surface of the fermentation but yields from inulin are 20-30% lower than from sucrose, the traditional commercial substrate.
