The correct answer is Option (2) -1-d,2-c,3-b,4-a
| Column 1 |
Column 2 |
| 1)Saccharomyces cerevisiae |
d) Bread |
| 2)Propionibacterium sharmanii. |
c) Swiss cheese |
| 3) Penicillium notatum |
b) Penicillin |
| 4)Acetobacter aceti |
a) Acetic acid |
Saccharomyces cerevisiae - (d) Bread
Explanation: Saccharomyces cerevisiae is a species of yeast commonly used in baking. It ferments sugars, producing carbon dioxide and ethanol, which causes the dough to rise and results in the production of bread.
Propionibacterium shermanii - (c) Swiss cheese
Explanation: Propionibacterium shermanii is a bacterium used in the production of Swiss cheese. It produces carbon dioxide during fermentation, which forms the characteristic holes (or "eyes") in the cheese, and also contributes to the cheese's distinct flavor.
Penicillium notatum - (b) Penicillin
Explanation: Penicillium notatum is a mold that produces penicillin, the first antibiotic discovered. Penicillin is used to treat bacterial infections and was a major breakthrough in medicine.
Acetobacter aceti - (a) Acetic acid
Explanation: Acetobacter aceti is a bacterium used in the production of acetic acid, the main component of vinegar. It converts ethanol (alcohol) into acetic acid during fermentation.
