Fungi Used in Antibiotic Production — NEET Biology
📚 Practice ConceptName any two species of fungus, which are used in the production of the antibiotics.
Which of the above statements are NOT correct? S1: The puffed-up appearance of bread is primarily due to the production of lactic acid by bacteria during fermentation. S2: Cyclosporin A, an immunosuppressive agent, is produced by the bacterium Trichoderma polysporum. S3: The large holes in Swiss cheese result from the extensive CO2 production by the bacterium Propionibacterium sharmanii. S4: Statins, used as blood-cholesterol lowering agents, are produced by the yeast Monascus purpureus. S5: Acetobacter aceti, a fungus, is responsible for the commercial production of acetic acid.
View solution & NCERT explanation
Correct answer: A — S1, S2 and S5 only
This question aims to identify incorrect statements regarding various microbial products and their producing organisms, emphasizing the precise details from NCERT. S1: This statement is incorrect. The puffed-up appearance of bread is due to the production of CO2 gas by baker's yeast (Saccharomyces cerevisiae), not lactic acid by bacteria. S2: This statement is incorrect. Cyclosporin A is produced by the fungus Trichoderma polysporum, not a bacterium. S3: This statement is correct. NCERT explicitly states, "The large holes in ‘Swiss cheese’ are due to production of a large amount of CO2 by a bacterium named Propionibacterium sharmanii." S4: This statement is correct. NCERT mentions, "Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents." S5: This statement is incorrect. Acetobacter aceti is a bacterium (not a fungus) that is responsible for the production of acetic acid. Therefore, statements S1, S2, and S5 are NOT correct. This question requires an accurate recall of the specific microbes, their correct classification (bacterium, fungus, yeast), and the particular products or effects associated with them, covering both household and industrial applications.
