Which one of the following is a wrong matching of a microbe and its industrial product, while the remaining three are correct?
Yeast - statins
Acetobacter acetic - acid
Clostridium butulicum - lactic acid
Aspergillus niger - citric acid
Solution
1. Yeast \(\rightarrow\) Statins:
- Incorrect. Statins are cholesterol-lowering drugs that are typically produced by fungi like Monascus purpureus, not yeast. Yeast (Saccharomyces cerevisiae) is primarily used for ethanol production.
2. Acetobacter aceti \(\rightarrow\) Acid:
- Correct. Acetobacter aceti is used in the production of acetic acid (vinegar).
3. Clostridium butylicum \(\rightarrow\) Lactic acid:
- Incorrect. Clostridium butylicum is used for the production of butyric acid, not lactic acid. Lactic acid is typically produced by Lactobacillus species.
4. Aspergillus niger \(\rightarrow\) Citric acid:
- Correct. Aspergillus niger is widely used for the industrial production of citric acid.
Correct Answer:
(3) Clostridium butylicum \(\rightarrow\) Lactic acid \(\checkmark\) This is the wrong match, while the other three are correct.
