Online published on 9 November, 2023. Abstract Increasing cost of production and global demand for citric acid is driving research towards optimizing process conditions to yield very high quantity of the organic acid using abundant cheap substrates and selected microorganisms. Citric acid is produced mainly by submerged aerobic fermentation using fungal strain of Aspergillus niger. The present paper reports the study of process parameter such as selection of Cheap raw material and its percent dilution, pH, temperature and incubation period under the influence of some citric acid producing fungus such as : Aspergillus fischeri SS-20, A. foetidus SS-21. A. aculeatuas SS-22, A. carbonarius SS- 23 and A. wentii SS-24 has been assessed for their citric acid producing capacity. Among the fungal species, A. wentii SS-24 is known as a potential producer of citric acid. It has been found that production of citric acid by A. wentii SS-24 proceeds best when molasses solution 25% (w/v) is allowed to ferment for 11 days of incubation period at 35°C temperature by maintaining pH value of fermentation medium to 2.1 along with some other nutritional ingredients required by the fungus A. wentii SS-24. Therefore, utilization of low-cost sugar industry bioproduct molasses which serve as suitable substrate for optimization of citric acid production is advocated because of their advantages such as income generation, reduction in environmental problems and public health hazards associated with it. Top Keywords Citric acid fermentation, Molasses, A. wentii SS-24. Top |
