Question

Bacillus ramosus and Bacillus vulgaris are examples of

• A. Ammonifying bacteria
• B. Nitrate bacteria
• C. Nitrite bacteria
• D. Symbiotic bacteria

Answer 1

The correct option is A

Ammonifying bacteria

The correct option is A.

Explanation of correct option-

1. Ammonifying bacteria are bacteria that convert ammonia into atmospheric nitrogen.
2. They can be either symbiotic or non-symbiotic.
3. Symbiotic ammonifying bacteria form root nodules and supply the ammonia to the plant.
4. Non-symbiotic bacteria live openly & use ammonia for their own metabolism.
5. Examples of Ammonifying bacteria include Bacillus vulgaris and Bacillus ramosus.

Explanation of incorrect option-

Option B:

1. The bacteria that converts the ammonia into nitrate is called nitrifying bacterIa.
2. This process is called nitrification.
3. Nitrobacter, Nitrospina bacteria convert nitrites to nitrates.

Option C:

1. During nitrification process, ammonia is first converted into nitrite and later to nitrate.
2. Nitrosospira, Nitrosomonas bacteria convert the ammonia into nitrites.

Option D:

1. Symbiotic bacteria are those bacteria that are found in symbiotic relationship with other organisms.
2. Rhizobium, Azospirillum are the examples of symbiotic bacteria.

Final answer: Bacillus ramosus and Bacillus vulgaris are examples of Ammonifying bacteria.
