Find the odd one w.r.t nitrifiying bacteria:

Options

A. Nitrococus
B. Nitrobacter
C. Nitrosomonas
D. Chlorobium

Answer

To solve the question of finding the odd one with respect to nitrifying bacteria, we can follow these steps:

### Step 1: Understand the concept of nitrifying bacteria
Nitrifying bacteria are microorganisms that play a crucial role in the nitrogen cycle by converting ammonia (NH3) into nitrates (NO3-). This process is known as nitrification.

**Hint:** Remember that nitrifying bacteria are involved in the conversion of ammonia to nitrate.

### Step 2: Identify the process of nitrification
Nitrification occurs in two main steps:
1. The conversion of ammonia to nitrites (NO2-) by bacteria such as Nitrosomonas.
2. The conversion of nitrites to nitrates by bacteria such as Nitrobacter.

**Hint:** Nitrification involves two key steps and two types of bacteria.

### Step 3: List common nitrifying bacteria
Some common examples of nitrifying bacteria include:
- Nitrosomonas
- Nitrobacter
- Nitrospira
- Nitrocystis

**Hint:** Familiarize yourself with the names of nitrifying bacteria to identify any that do not belong.

### Step 4: Identify the odd one out
From the examples given, we need to find the one that does not belong to the category of nitrifying bacteria. The question mentions Nitrolobium, which is not a nitrifying bacterium.

**Hint:** Look for any names that do not fit the category of nitrifying bacteria.

### Step 5: Conclude the answer
The odd one out with respect to nitrifying bacteria is Nitrolobium, as it does not participate in the nitrification process.

**Final Answer:** Nitrolobium is the odd one with respect to nitrifying bacteria.
