“…Prolonged incubation did not further increase the citric acid production. In similar studies, the researchers reported the optimum incubation time as between 144-240 hours (Currie, 1917;Wieczorek and Brauer, 1998;Demirel, 2003;Peksel, 2003;Max et al, 2010;Apelblat, 2016). Rajoka et al (1998) reported that they achieved a product formation rate of 0.0506 g/L/ hour.…”

Citric acid is one of the most remarkable industrial goods fabricated by industrial fermentation using filamentous fungus. When Aspergillus niger, a filamentous fungus, is produced under suitable conditions, high amounts of citric acid are obtained. This study aims to explain the citric acid synthesis studied in a biodisc reactor using A. niger. Various physiological parameters have been investigated in order to determine the optimum citric acid synthesis in biodisc reactor. Optimum incubation time was found to be as 168 hours in the study. The optimum value of the incubation temperature was determined to be 30°C. The optimum value of the initial pH was found to be 3.8. Optimum citric acid synthesis occurred when the disc rotation speed was 2 rpm. In addition, the optimum value of the initial sugar (sucrose) concentration was determined to be 20%. In a semi-continuous production study with the renewal of the medium after a certain incubation period, it was determined that the citric acid yield increased approximately 3 times compared to the batch system. As a result, the highest value of citric acid was determined as 67.65 g/L.

“…According to the researchers, it is known that over 90% of citric acid fabrication in the globe is handled by fermentation. In the yield of citric acid by fermentation, the filamentous fungus Aspergillus niger and the yeast Yarrowia lipolytica are mainly used (Max et al, 2010;Wyrzykowski et al, 2011;Souza et al, 2014;Apelblat, 2016).…”
