Question

Large scale industrial production of citric acid for human welfare is done using the microbe:

• A. Streptococcus sp.
• B. Aspergillus sp.
• C. Clostridium sp.
• D. Trichoderma sp.

Hint:

Aspergillus niger is a key microbe in citric acid production, often using molasses or glucose as a substrate in fermentation.

Answer 1

The Correct Option is B

Aspergillus sp., particularly Aspergillus niger, is widely used for the industrial production of citric acid due to its efficiency in fermenting sugars into citric acid. Streptococcus, Clostridium, and Trichoderma are not typically used for this purpose.
