Bacteria connected with acetogenesis is

Options

A. Streptomonas
B. Clostridium
C. Bacillus
D. Citromonas.

Answer

To solve the question of which bacteria is connected with acetogenesis, we can follow these steps:

### Step 1: Understand Acetogenesis
Acetogenesis is the process by which acetate is produced from carbon dioxide by anaerobic bacteria. This process occurs in the absence of oxygen and involves the conversion of carbon dioxide into acetate using reductive acetyl coenzyme A.

**Hint:** Remember that acetogenesis specifically refers to the production of acetate from carbon dioxide by anaerobic bacteria.

### Step 2: Identify the Electron Sources
In the process of acetogenesis, the electron sources include hydrogen, carbon monoxide, and formate. This is important because it helps to identify the types of bacteria that can perform this process.

**Hint:** Think about the types of substrates that anaerobic bacteria can utilize during acetogenesis.

### Step 3: Know the Organisms Involved
Organisms that perform acetogenesis are known as acetogens. Some examples of acetogens include Citromonas and Acetobacter.

**Hint:** Focus on the term "acetogen" to help identify the correct bacteria.

### Step 4: Analyze the Options Given
Now, let's analyze the options provided in the question:
1. **Streptomonas** - This is not known for acetogenesis.
2. **Clostridium** - While some species are anaerobic, they are not primarily known for acetogenesis.
3. **Bacillus** - This is generally aerobic and not associated with acetogenesis.
4. **Citromonas** - This is known to be involved in acetogenesis.

**Hint:** Compare each option to the characteristics of acetogens to determine which one fits.

### Step 5: Conclusion
Based on the analysis, the bacteria connected with acetogenesis is **Citromonas**.

**Final Answer:** Citromonas
