UPSC Prelims PYQ 2010: Bacterial strain used for treating oil spills

Which bacterial strain, developed from natural isolates by genetic manipulations, can be used for treating oil spills?

  1. Agrobacterium
  2. Clostridium
  3. Nitrosomonas
  4. Pseudomonas

Explanation

Option (d) is correct
  • Certain species of Pseudomonas possess the natural ability to degrade hydrocarbons present in crude oil and petroleum products. Through genetic manipulation, strains of Pseudomonas have been developed that can efficiently metabolise a wide range of hydrocarbons. These bacteria use hydrocarbons as a source of carbon and energy, breaking them down into less harmful substances.
