Sucrose + [2 Pi, 4Pi]+[4 ADP, 2 ADP, 4 ATP, 2ATP]+[2 NAD+, 4 NAD+, 6 NAD+]+[H2O, 5 H2O, 3 H2O] --> [2 cirate, 2 oxaloacetate, 2 pyruvate, 2 acetyl-coA]+[4 ADP, 2 ADP, 4 ATP, 2ATP] + [2 NAD+, 4 NAD+, 6 NAD+] + [2H+, 8H+, 6 H+, 4 H+, 10 H+]
 
 
Does the commercial process require aerated culture medium—that is, is this a fermentation or an aerobic process?
A. a fermentation process, because A. niger cells must use O2O2 to continuously regenerate NAD+
B. an aerobic process, because A. niger cells must use O2O2 to continuously regenerate NAD+
C. a fermentation process, because A. niger cells cannot use O2O2 to continuously regenerate NAD+
D. an aerobic process, because A. niger cells cannot use O2O2 to continuously regenerate NAD+
Manufacturers use citric acid as a flavoring agent in soft drinks, fruit juices, and many other foods. Worldwide, the market for
citric acid is valued at hundreds of millions of dollars per year. Commercial production uses the mold Aspergillus niger, which
metabolizes sucrose under carefully controlled conditions.
The yield of citric acid strongly depends on the concentration of FeCl3 in the culture medium, as indicated in the graph.
