Which of the following organism helps in the production of beverages?

Saccharomyces cerevisiae.

The correct answer is Option (4) - Saccharomyces cerevisiae

Explanation:
Saccharomyces cerevisiae, also known as brewer’s yeast, is the organism used in the production of alcoholic beverages like beer and wine. It carries out fermentation, converting sugars into alcohol (ethanol) and carbon dioxide. This process is essential for brewing and winemaking.

The other options are not used for beverage production:

• Penicillium notatum → used for producing penicillin (antibiotic).
• Clostridium butylicum → used in industrial production of butyric acid.
• Aspergillus niger → used for citric acid production.

Therefore, only Saccharomyces cerevisiae is the correct organism for beverage production.
