Options

A. Trichoderma sp
B. Aspergillus niger
C. Pseudomonas putida
D. All of these

Answer

To solve the question "Which of the following microbe is widely used in the removal of industrial wastes?", we will analyze each of the given options step by step.

### Step 1: Understand the Question
The question is asking for a microbe that is widely used in the removal of industrial wastes. Industrial waste can include a variety of substances that need to be broken down or removed.

**Hint:** Focus on the role of microbes in waste management and their specific applications.

### Step 2: Analyze Each Option
1. **Trichoderma Species**
- Trichoderma is a genus of fungi known for its ability to decompose organic matter. It increases the rate of decomposition, which can be beneficial in breaking down industrial waste.
- **Conclusion:** This option is relevant to the removal of industrial waste.

2. **Aspergillus niger**
- Aspergillus niger is another fungus that is known for its ability to remediate nitrogenous waste. It can break down various organic compounds, making it useful in waste treatment.
- **Conclusion:** This option is also relevant to waste removal.

3. **Pseudomonas putida**
- Pseudomonas putida is a bacterium known for its ability to degrade a wide range of organic pollutants, particularly in wastewater treatment. It is effective in removing contaminants from industrial effluents.
- **Conclusion:** This option is relevant as well.

4. **All of the above**
- Since all the previous options (Trichoderma species, Aspergillus niger, and Pseudomonas putida) are known to play a role in the removal of industrial waste, this option suggests that all the mentioned microbes are involved in waste removal.
- **Conclusion:** This option is correct as it encompasses all the previous options.

### Step 3: Select the Correct Answer
Given that all three microbes mentioned (Trichoderma species, Aspergillus niger, and Pseudomonas putida) are involved in the removal of industrial waste, the correct answer is:
**All of the above.**

### Final Answer:
**All of the above**
