Question

Monascus purpureus is yeast used commercially in production of

• A. Ethanol
• B. Citric acid
• C. Streptokinase for removing clots in blood vessels
• D. Blood cholesterol lowering statins

Answer 1

The Correct Option is D

Monascus purpureus is a species of yeast that plays a significant role in biotechnology, particularly in the production of substances used in health-related applications. Let's explore each option to identify the correct answer:

1. Ethanol: Typically produced by yeast species such as Saccharomyces cerevisiae, ethanol is a common product of fermentation. However, Monascus purpureus is not known for ethanol production, making this option incorrect.
2. Citric acid: This organic acid is industrially produced by species like Aspergillus niger rather than Monascus purpureus, ruling out this option.
3. Streptokinase for removing clots in blood vessels: Streptokinase is an enzyme produced by strains of Streptococcus bacteria, not yeast, which means Monascus purpureus is unrelated to this option.
4. Blood cholesterol lowering statins: This is the correct option. Monascus purpureus is utilized commercially to produce statins, specifically lovastatin, which helps in lowering blood cholesterol levels by inhibiting the enzyme HMG-CoA reductase in the body.

Based on the analysis, the correct answer is: Blood cholesterol lowering statins.
