Which of thedollowing genetically engineered microbe is used in scavening of oil spills by digesting hydocarbons of crude oil?

Options

A. Pseudomonas fluorescence
B. Rhizobium meliloti
C. Pseudomonas putida
D. Trichoderma

Answer

To answer the question regarding which genetically engineered microbe is used in the scavenging of oil spills by digesting hydrocarbons of crude oil, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question asks for a genetically engineered microbe that can digest hydrocarbons found in crude oil, specifically for the purpose of cleaning up oil spills.

2. **Identify the Process**: The process of using living organisms to remove contaminants from the environment is known as **bioremediation**. This involves using microbes, fungi, or yeast to break down pollutants.

3. **Analyze the Options**: The options provided are:
- Pseudomonas fluorescens
- Pseudomonas meleolotes
- Pseudomonas patida
- Trichoderma

4. **Focus on Pseudomonas Species**: Among the options, Pseudomonas species are known for their ability to degrade various organic pollutants, including hydrocarbons.

5. **Select the Correct Microbe**: Based on the knowledge that certain genetically engineered strains of Pseudomonas are used in bioremediation, the correct answer is **Pseudomonas patida**. This specific strain has been modified to effectively digest hydrocarbons present in crude oil, making it suitable for cleaning oil spills.

6. **Conclusion**: Therefore, the genetically engineered microbe used in scavenging oil spills by digesting hydrocarbons of crude oil is **Pseudomonas patida**.
