Question

Match the following:

List I (Organism/Enzyme)	List II (Product/Use)
I. Aspergillus niger	D. Citric acid
II. Clostridium butylicum	C. Butyric acid
III. Lipase	A. Detergent formulation
IV. Saccharomyces	B. Ethanol

• A. I B, II D, III A, IV C
• B. I D, II C, III A, IV B
• C. I A, II C, III B, IV D
• D. I D, II A, III C, IV B

Hint:

Remember microbes by products: \textit{Aspergillus} for citric acid, \textit{Saccharomyces} for ethanol, Lipase for detergents, \textit{Clostridium} for butyric acid.

Answer 1

The Correct Option is B

- I. \textit{Aspergillus niger} → Citric acid: This fungus is widely used in the industrial production of citric acid through fermentation.
- II. \textit{Clostridium butylicum} → Butyric acid: This anaerobic bacterium is known for producing butyric acid during fermentation.
- III. Lipase → Detergent formulation: Lipase enzymes break down fats and are used in detergents to remove oily stains.
- IV. \textit{Saccharomyces} → Ethanol: This genus (especially \textit{S. cerevisiae}) is used in alcoholic fermentation to produce ethanol.

Answer 2

Match the following:

The matching of organisms/enzymes with their products or uses is as follows:

I. Aspergillus niger - This fungus is widely used in industrial microbiology for the production of citric acid, which is an important organic acid used in food and pharmaceuticals.

II. Clostridium butylicum - This bacterium is known for producing butyric acid, a short-chain fatty acid important in various chemical and biochemical processes.

III. Lipase - This enzyme catalyzes the breakdown of fats and oils and is commonly used in detergent formulations to help remove grease stains.

IV. Saccharomyces - This genus of yeast is extensively used in fermentation processes to produce ethanol, which is used in alcoholic beverages and as biofuel.

Correct Matching:
I - D. Citric acid
II - C. Butyric acid
III - A. Detergent formulation
IV - B. Ethanol
