Taq DNA polymerase was isolated from the hot springs bacterium called

Options

A. Tetrahymenia thermophila
B. Thermophilus aquaticus
C. Clostridium botulinum
D. Bacillus licheniformis

Answer

To answer the question about the source of Taq DNA polymerase, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Taq DNA Polymerase**:
- Taq DNA polymerase is a type of DNA polymerase that is known for its heat stability. This property makes it particularly useful in the polymerase chain reaction (PCR) process, which involves repeated heating and cooling cycles.

2. **Identifying the Source**:
- Taq DNA polymerase is derived from a specific bacterium that thrives in high-temperature environments, such as hot springs. This bacterium is classified as thermophilic, meaning it can survive and function at elevated temperatures.

3. **Evaluating the Options**:
- The question provides four options:
- A) Tetrahymena thermophilia
- B) Thermus aquaticus
- C) Clostridium fortuitum
- D) Bacillus lechiniformis
- We need to identify which of these options is known to produce Taq DNA polymerase.

4. **Correct Identification**:
- Among the options, **Thermus aquaticus** (option B) is the correct answer. This bacterium is well-known for being the source of Taq DNA polymerase, as it is found in hot springs and is capable of withstanding high temperatures.

5. **Final Answer**:
- Therefore, the correct answer to the question is **option B: Thermus aquaticus**.
