View answer and explanation
Correct option: D
All of these
Correct Answer + Core Reason: All of these. All listed microbes are used in industrial waste removal.
Step-by-Step Solution:
Step 1: Consider the role of microbes in waste management.
Step 2: Tricoderma sp. can degrade pollutants.
Step 3: Aspergillus niger can remove heavy metals.
Step 4: Pseudomonas putida is known for bioremediation of pollutants.
Step 5: Therefore, all the given microbes are used in the removal of industrial wastes.
Why other options are wrong:
- Option A: Tricoderma sp. is correct but not complete as it doesn't include all possible microbes.
- Option B: Aspergillus niger is correct but not complete as it doesn't include all possible microbes.
- Option C: Pseudomonas putida is correct but not complete as it doesn't include all possible microbes.
Key Concepts:
- Bioremediation
