Question

What is not true for ammonification?
a. Carried out by saprophytic microbes
b. Organic nitrogen is converted in ammonia
c. Carried out by bacillus ramosus bacteria
d. Protein are directly converted into ammonia without any intermediate

Answer 1

Hint: We know the microscopic organisms such as bacteria or other types of organisms ought to decompose the food materials. Such types of microorganisms normally break down the chemicals which comprise the element nitrogen from the source of dead and decaying organic matter. This process is called Ammonification.
Thus, we can conclude that the process of Ammonification includes the breakdown of compounds containing complex molecules into simpler ions just like ammonia which contain nitrogen in it.

Complete answer:
- The process of ammonification is carried out by certain bacteria just like Bacillus ramosus, B. vulgaris, Clostridium, Actinomyces, etc. In this process, these organisms release a specific amount of nitrogen compounds like ammonia. However, saprophytic bacteria will not be involved in this process.

- The saprophytic bacteria will decompose the product of dead animals but not in the form of nitrogen compounds.

- As mentioned above in this process, the conversion of organic nitrogen content present in the dead and putrefying matter into salts of ammonium which further undertakes the process of nitrification to get transformed into a usable form.

- This breakdown is completed with the help of the microorganisms (called decay bacteria) which exploit organic material from the dead for energy and in turn, they produce ammonia. Here the Protein present in plants and animals are directly converted into ammonia. There are no intermediate products.

- As we already know that the Proteins and nucleic acids are present in the dead and departed remains of florae, faunae. This also includes the excretory products of animals. Such materials are tarnished with the help of microorganisms present near them.

Hence, The correct answer is option (A).

Note: The organic matter is consumed by decomposing the microbes. Moreover, the nitrogen present in them is made to form into ions of ammonium. Further, in this process, the ammonium ions are converted into nitrates with the help of the nitrifying bacteria.
