(a)
To determine: The reason of decrease in the yield of citric acid when the [Fe3+] varies from the optimal value.
Introduction:
Citrate is the first product of citric acid cycle. it is obtained from the enzymatic activity of citrate synthase on oxaloacetate and acetyl CoA. Citrate is produced commercially and added as flavoring agent in some foods, juices, and soft drinks.
(b)
To determine:
Determine the overall reaction of citric acid from sucrose.
Introduction:
Aspergillus niger is a mold species which is used to produce citric acid by the
(c)
To determine:
Whether the commercial production of sugar is fermentation or aerobic process.
Introduction:
Fermentation refers to the chemical breakdown of the substances by the active involvement of yeasts, bacteria and microbes. Aerobic respiration is the breakdown of glucose in pyruvate in order to obtain energy, in the presence of molecular oxygen.
