Question

A genetically engineered bacteria used for clearing oil spills is

• A. Escherischia coli
• B. Bacillus subtilis
• C. Agrobacterium tumifaciens
• D. Pseudomonas putida

Answer 1

The correct option is D Pseudomonas putida

Pseudomonas putida is a Gram-negative, rod shaped, aerobic, chemoheterotrophic bacterium. Being chemoheterotrophic, they use organic compounds as source of their energy. This bacterium can break down any of aliphatic and aromatic hydrocarbons. Most of the organic toxins are aliphatic and aromatic hydrocarbons. Genetically engineered marine-dweller Pseudomonas putida use hydrocarbons as fuel and break down the ring structures of the hydrocarbons in oil spill in presence of enzymes and seawater oxygen and emit carbon dioxide.

so, the correct answer is 'Pseudomonas putida'
