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 کاملSudden substrate dilution induces a higher rate of citric acid production by Aspergillus niger.
On the basis of the present knowledge of Aspergillus niger metabolism during citric acid fermentation, an idea on how to improve the process was formed. Initially, a higher sucrose concentration was used for the germination of spores, which caused a higher intracellular level of the osmoregulator, glycerol, to be present. When citric acid started to be excreted into the medium, the substrate wa...
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...
متن کاملSTUDY of the INFLUENCE of NUTRIENTS on CITRIC ACID PRODUCTION by Aspergillus niger UNDER SOLID STATE FERMENTATION USING RICE CHAFF and SESAMUM OIL CAKE as SUBSTRATE
Abstract: The main aim of this study is to investigate about citric acid production by ETGP12 and ETGP18 strains of Aspergillus niger with the inclusion of certain nutrients along with the substrates. The substrates (rice chaff and sesamum oil cake) were fermented in the presence of different nutrients like ammonium carbonate and potassium dihydrogen phosphate at concentrations ranging from 0.1...
