Question

Example of an ammonifying bacteria is
A. Clostridium
B. Azotobacter
C. Nitrosococcus
D. Bacillus ramosus

Answer 1

Hint: Ammonifying bacteria helps in the production of ammonia. Ammonification of soil is defined as decomposition with the production of ammonium compounds by the action of bacteria.

Complete Answer:
Other than bad bacterias, many good bacterias are present in our body. Ammonifying bacteria like clostridium, pseudomonas etc. produce ammonia from organic compounds that are present in the atmosphere.
It converts atmospheric nitrogen into ammonia. Some examples of ammonifying bacteria are bacillus, clostridium, pseudomonas and Streptomyces which helps in the ammonification process of nitrogen.

The correct option is, A-Clostridium.

Additional information:
1) Azotobacter is free living diazotrophic bacteria whose resting stage is a cyst. It is primarily found in neutral to alkaline soils, in aquatic environments, and on some plants.
2) It has several metabolic capabilities including atmospheric nitrogen fixation.
3) Nitrosococcus is a marine, gram negative, ammonia oxidizing bacterium. Its main source of energy is from oxidizing ammonia. In return it releases nitrogen and nitrogen oxide.
4) Bacillus ramous converts ammonia into atmospheric nitrogen. It is a non-symbiotic bacteria that ammonifies live openly and uses ammonia for their own metabolism.

Note: Nitrogen cycle is a biogeochemical cycle by which nitrogen is converted into many forms. Ammonifying bacteria can be either symbiotic or non-symbiotic. The symbiotic ammonifying bacteria form root nodules and provide ammonia or ammonium to the plant. Non symbiotic ammonifying bacteria live freely and use ammonia for their own metabolism. This kind of bacteria plays an important role in nitrogen cycle.
