Question

Which of the following microbes dominate in ANAMMOX process?

• A. Autotrophs
• B. Heterotrophs
• C. Aerobic
• D. Phototrophs

Hint:

ANAMMOX bacteria reduce energy and carbon requirements by avoiding organic carbon addition.

Answer 1

The Correct Option is A

Step 1: Understanding the ANAMMOX process.
ANAMMOX (Anaerobic Ammonium Oxidation) is a biological process in which ammonium is oxidized using nitrite as an electron acceptor under anaerobic conditions.
Step 2: Nature of microorganisms involved.
The microbes responsible for ANAMMOX are chemoautotrophic bacteria that use inorganic carbon (CO\(_2\)) as their carbon source.
Step 3: Analyzing the options.
(A) Autotrophs: Correct, as ANAMMOX bacteria are autotrophic in nature.
(B) Heterotrophs: Incorrect, they require organic carbon.
(C) Aerobic: Incorrect, ANAMMOX occurs under anaerobic conditions.
(D) Phototrophs: Incorrect, light is not involved.
Step 4: Conclusion.
The ANAMMOX process is dominated by autotrophic microorganisms.
