A genetically engineered bacteria used for clearing oil spills is:

Options

A. E.coili
B. Acetobacter aerrogenes
C. Psedomonas putida
D. Trichoderma

Answer

To answer the question "A genetically engineered bacteria used for clearing oil spills is:", we need to identify the specific bacterium that has been modified for bioremediation purposes, particularly in the context of oil spills.

### Step-by-Step Solution:

1. **Understanding Bioremediation**: Bioremediation is a process that uses microorganisms to remove or neutralize contaminants from a polluted environment. In the case of oil spills, specific bacteria can be engineered to break down hydrocarbons present in oil.

2. **Identifying Commonly Used Bacteria**: One of the most commonly referenced genetically engineered bacteria for oil spill remediation is *Pseudomonas putida*. This bacterium is known for its ability to degrade various organic pollutants, including oil.

3. **Genetic Engineering Aspect**: *Pseudomonas putida* can be genetically modified to enhance its oil-degrading capabilities. Scientists can insert specific genes that allow the bacteria to metabolize oil more efficiently.

4. **Conclusion**: Therefore, the genetically engineered bacteria that is widely recognized for clearing oil spills is *Pseudomonas putida*.

### Final Answer:
The genetically engineered bacteria used for clearing oil spills is *Pseudomonas putida*.
