Question

What type of bacteria converts the ammonia and ammonium into nitrates and nitrites?

Answer 1

Bacteria converts the ammonia and ammonium into nitrates and nitrites is described below.

Explanation:

1. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants. Denitrifying bacteria converts nitrates back to nitrogen gas.

2. The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter, Nitrospina, and Nitrococcus).

3. Nitrifying bacteria present in the soil convert ammonia into nitrite. Nitrite is then converted into nitrate. This process is called Nitrification.

4. De-Nitrification: Nitrogen in its nitrate form (NO3–) is converted back into atmospheric nitrogen gas (N2) by bacterial species such as Pseudomonas and Clostridium, usually in anaerobic conditions. These bacteria use nitrate as an electron acceptor instead of oxygen during respiration

Answer 2

Nitrifying bacteria are the type of bacteria that converts the ammonia and ammonium into nitrates and nitrites.

Nitrification is part of the so-called nitrogen cycle, which consists of several stages.

Nitrifying bacteria are:

• Chemoautotrophic bacteria (they synthesize by themselves all the chemical components of their structures from simple chemical elements).

• Chemolithotrophic bacteria (they synthesize all chemical components of their structures from inorganic compounds, and obtain energy during this process).

These bacteria are very abundant in nature, found in the soil, in lakes and in river currents with a high content of wastewater.

• The ammonia in the soil from the urine of animals or from the action of fixing bacteria serves as food for other types of microorganisms, in this case nitrifying bacteria.

• These bacteria break down ammonia and oxidize it to nitrites (NO2–), and then the nitrites are oxidized to nitrates (NO3–).

Therefore, we can conclude that nitrifying bacteria are the type of bacteria that converts the ammonia and ammonium into nitrates and nitrites.
