| 摘要 |
FIELD: biotechnology. SUBSTANCE: invention relates to method of production of citric acid by fermentation of carbohydrate-containing raw by submerged culture of mold fungus Aspergillus niger. Method provides to obtain conversion of sugars to citric acid up to 88.7% and increase productivity of process by 25-35% (by citric acid). EFFECT: increased efficiency, decreased reagent consumption, in part, potassium hexacyanoferroate, decreased energy consumption, simplified procedure. |
