Which of the following is NOT an example of bioremediation?
Show Hint
• Bioremediation → Cleaning environment
• Not → Causing environmental damage
Updated On: May 13, 2026
- Cleaning of oil spills by Pseudomonas putida
- Decomposition of DDT by Acetobacter aerogenus
- Removal of metal pollutants by Pseudomonas species
- Depletion of ozone by Aspergillus niger
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Bioremediation involves the use of microorganisms to remove or neutralize environmental pollutants.
• Includes degradation of toxic chemicals and pollutants
• Helps in environmental cleanup
Step 1: Analyzing each option.
• Oil spill cleanup: Microbial degradation → Bioremediation.
• DDT decomposition: Breakdown of pesticide → Bioremediation.
• Metal removal: Microbial detoxification → Bioremediation.
• Ozone depletion: Environmental damage, not pollutant removal → Not bioremediation.
Step 2: Selecting the correct answer.
Thus, depletion of ozone is not an example of bioremediation.
• Includes degradation of toxic chemicals and pollutants
• Helps in environmental cleanup
Step 1: Analyzing each option.
• Oil spill cleanup: Microbial degradation → Bioremediation.
• DDT decomposition: Breakdown of pesticide → Bioremediation.
• Metal removal: Microbial detoxification → Bioremediation.
• Ozone depletion: Environmental damage, not pollutant removal → Not bioremediation.
Step 2: Selecting the correct answer.
Thus, depletion of ozone is not an example of bioremediation.
