Pseudomonas putida carries plasmids for hydrolyzing

Options

A. hydrocarbons
B. petroleum products
C. crude oil
D. All of these

Answer

### Step-by-Step Solution:

1. **Identify the Organism**: The question mentions "Pseudomonas putida." This is a type of bacteria that is known for its ability to degrade various organic compounds.

2. **Characteristics of Pseudomonas putida**: It is a gram-negative, rod-shaped bacterium that is commonly found in soil. It plays a crucial role in bioremediation, which is the process of using organisms to remove or neutralize contaminants from the environment.

3. **Function in Bioremediation**: Pseudomonas putida carries plasmids that enable it to hydrolyze (break down) various hydrocarbons, which include petroleum products and crude oil. This hydrolysis process converts these harmful substances into biodegradable forms, thus helping to clean up the environment.

4. **Options Provided**: The question asks whether Pseudomonas putida can hydrolyze hydrocarbons, petroleum products, crude oil, or all of these.

5. **Analysis of Options**:
- Hydrocarbons: Yes, Pseudomonas putida can hydrolyze hydrocarbons.
- Petroleum Products: Yes, it can also hydrolyze petroleum products.
- Crude Oil: Yes, it can hydrolyze crude oil as well.

6. **Conclusion**: Since Pseudomonas putida can hydrolyze all the mentioned compounds (hydrocarbons, petroleum products, and crude oil), the correct answer is "All of these."

### Final Answer:
**All of these** (hydrocarbons, petroleum products, crude oil).
