Answer :
Final answer:
The genetically manipulated bacterium used for treating oil spills is Pseudomonas, known for solubilizing and degrading oil in bioremediation processes.
The answer is (d) pseudomonas.
Explanation:
The bacterial strain that has been developed from natural isolates through genetic manipulation and can be used for treating oil spills is Pseudomonas. This bacterium is known for its capabilities in bioremediation, which includes solubilizing and degrading oil, thus helping to clean up after disastrous events such as the Exxon Valdez and BP oil spills. Scientists have worked on enhancing these natural capabilities by selecting and engineering bacteria like Alcanivorax borkumensis, which are efficient in breaking down hydrocarbons into smaller, less harmful components.
