Question

Which one of the following are genetically improved bacteria for pollution control?
A. Pseudomonas
B. Rhizobium
C. Nitrobacter
D. Nitrosomonas

Answer 1

The bacteria cause infections generally called pathogens They are usually found in the water, soil, and dump areas. GMOs are genetically modified organisms in which the genes are modified in such a way th

Complete answer:
Pseudomonas is naturally a biocontrol agent that is used for the bioremediation process.
Bioremediation is a branch of biotechnological science that includes the use of living organisms, such as microbes and bacteria, that help in the removal of contaminants, toxins, and pollutants from the environment – usually soil and water. In simple words, bioremediation is the cleaning up process of the contaminated environment.
Pseudomonas produce certain enzymes that help in the degradation of organic waste.
The strains of the Pseudomonas are genetically modified by scientists that help in the control of pollutants on a large scale. For example - oil that spills in the ocean water can be removed by the genetically modified Pseudomonas.
Some strains from Pseudomonas are transferred in E. coli that help to produce the enzymes that are capable of degrading even organic compounds. This helps to increase the production capacity of enzymes.
So, the correct answer is option A-Pseudomonas.

Note: There is another similar term – phytoremediation, which can be defined as the bioremediation process that uses various types of plants for the removing, transferring, stabilizing, and/or destroying the contaminants present in the soil and groundwater. The Rhizobium is a nitrogen-fixing bacteria. Nitrobacter and Nitrosomonas are the bacteria that help to convert ammonia to nitrate and nitrite.
