Q14. In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation techniques?
- It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature.
- Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using microorganisms
- Genetic engineering can be used to create microorganisms specifically designed for bioremediation
Select the correct answer using the codes given below
a) 1 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and
The correct answer is 1 and 3 only.
- Bioremediation technique
- Bioremediation is a treatment that involves the use of naturally occurring organisms to convert hazardous substances into less toxic or non-toxic substances.
- It degrades organic contaminants in soil, groundwater, sludge, and solids using microorganisms.
- The bioremediation technique is a method of cleaning up pollution by enhancing the natural biodegradation process. Hence, Statement 1 is correct.
- Not all contaminants are easily treated by microorganism-based bioremediation. Heavy metals, for example, cadmium and lead, are not easily absorbed or captured by microorganisms.
- Bioremediation is only applicable to biodegradable compounds. Hence, Statement 2 is not correct.
- Bioremediation is the process of degrading environmental contaminants using microorganisms, primarily bacteria and fungi.
- Using genetic engineering, microorganisms specifically designed for bioremediation can be created. Hence, Statement 3 is correct.
