Question

Genetically altered bacterium used in the control of environment pollution is

• A. E.coli
• B. Bacillus anthracis
• C. Pseudomonas
• D. Agrabacterium

Answer 1

Answer: (C)

Pseudomonas

Aliphatic and aromatic hydrocarbons, crude oil, nitroaromatic compounds are successfully degraded by a wide range of Pseudomonas sp. Most of the strains contained a catabolic plasmid, which encodes the genes for hydrocarbon degradation. The biotransformation of this plasmid to various terrestrial and natural marine bacteria has been carried out, indicating the horizontal transfer of catabolic genes from one bacteria to another, to create "superbugs" for bioremediation program in ecosystems.

So, the correct answer is option C.
