In the context of solving pollution problems, what is/are the advantage/advantages of the bioremediation technique?

  1. 1.It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature.
  2. 2.Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using microorganisms.
  3. 3.Genetic engineering can be used to create microorganisms specifically designed for bioremediation.
  1. A.1 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: C. 1 and 3 only

Bioremediation leverages natural biological processes, often enhancing them, to break down or neutralize pollutants. This involves utilizing microorganisms to degrade contaminants, making it an environmentally friendly approach. Furthermore, advancements in genetic engineering allow for the development of specialized microorganisms with enhanced capabilities for treating specific types of pollution, including recalcitrant compounds.
