A genetically engineered microorganism used successfully in bioremediation of oil spills is a species of

Options

A. Xanthomonas
B. Bacillus
C. Pseudomonas
D. Trichoderma

Answer

To answer the question regarding a genetically engineered microorganism used successfully in bioremediation of oil spills, we can analyze the given options step by step.

### Step 1: Analyze the Options
We have four options to consider:
1. **Xanthomonas**
2. **Bacillus**
3. **Pseudomonas**
4. **Trichoderma**

### Step 2: Evaluate Each Option
- **Xanthomonas**: This genus is primarily known for its role in the production of xanthan gum, which is a polysaccharide used as a food additive. It is not primarily associated with bioremediation of oil spills.

- **Bacillus**: Specifically, Bacillus thuringiensis is well-known for producing the BT toxin, which is used as a bio-pesticide. While Bacillus species have various applications, they are not primarily recognized for bioremediation of oil spills.

- **Pseudomonas**: Pseudomonas putida is a well-documented microorganism that has been successfully used in bioremediation. It has the ability to degrade organic pollutants, including hydrocarbons found in oil spills. This makes it a strong candidate for the question.

- **Trichoderma**: This genus is mainly used as a biocontrol agent for soil-borne plant diseases and does not have a significant role in the bioremediation of oil spills.

### Step 3: Identify the Correct Answer
Based on the analysis, the correct answer is **Pseudomonas**, specifically Pseudomonas putida, as it is known for its effectiveness in degrading oil pollutants and has been genetically engineered for enhanced bioremediation capabilities.

### Final Answer
The genetically engineered microorganism used successfully in bioremediation of oil spills is a species of **Pseudomonas**.
