Citric Acid Production by Aspergillus Niger*
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 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 ...
متن کاملPurification and Characterization of Α-amylase Produced by Aspergillus Niger Using Banana Peels
The present study was aimed at purification and characterization of α-amylase enzyme from strain of Aspergillus niger isolated from local soil samples. Solid state fermentation (SSF) was carried out to produce α-amylase from A. niger using waste banana peel as substrate. The maximum activity of α-amylase (11926 U/gds) was recorded after 72 hours of fermentation. The extracted enzyme was subject...
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 Aspergillus niger using cane molasses in a stirred fermentor
The present investigation deals with the kinetics of submerged citric acid fermentation by Aspergillus niger using blackstrap molasses as the basal fermentation media. A laboratory scale stirred fermentor of 15-L capacity having working volume of 9-L was used for cultivation process and nutritional analysis. Among the 10 stock cultures of Aspergillus niger, the strain GCBT7 was found to enhance...
