Optimisation of Citric Acid Production from a Novel Strain of Aspergillus niger by Submerged Fermentation
Fungi isolated from various rotten fruits and vegetables were screened for the capability of producing citric acid. Aspergillus niger (A. niger) was obtained in the decayed onion peels and denoted as KON13 and this fungi strain was used in the production of citric acid by submerged fermentation. Critical process parameters affecting the fermentative citric acid production were investigated, inc...

the Stokes' equation (4). The anomalous appearance of the curves might suggest that a non-random sample had been selected, but examination of the frequencies of cells appearing in different size ranges reveals a normal distribution indicating that a random sample had been selected. The diameters of cells and the correspondent frequencies are: 3.5-2; 4.0-7; 4.5-10; 5.0-20; 5.5-17; 6.0-8; 6.5-2; ...
متن کاملcitric acid production from sugarcane bagasse through solid state fermentation method using aspergillus niger mold and optimization of citric acid production by taguchi method
background citric acid is produced in insignificant quantities in iran. despite its great range of utilizations, and from another aspect, high level of production of sugarcane bagasse, the related problems arising from maintenance of this acid require thinking of a measure in the direction of its optimal usage and production. objectives the objective of the present study is to obtain effectual ...
متن کاملAconitase and citric acid fermentation by Aspergillus niger.
In view of the often-cited theory that citric acid accumulation is caused by an inhibition of aconitase activity, the equilibrium of the reaction of aconitase was investigated by comparing in vivo steady-state concentrations of citrate and isocitrate in Aspergillus niger grown under various citric acid-producing conditions. With the equilibrium catalyzed by the A. niger enzyme in vitro, similar...
متن کاملProduction of citric acid by mutants of Aspergillus niger.
Development of methodology for the recovery of citric acid from the fermented broth involves standardization of the various parameters to achieve maximum performance in terms of recovery and optimum conditions. The present investigation was carried out to study the purification of citric acid from fermented broth by calcium carbonate precipitation and subsequent acid hydrolysis. The parameters ...
