Solution

The correct option is B

Pseudomonas putida


An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity and is a form of pollution. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters. Pseudomonas putida also called as oil guzzlers is a gram negative, rod shaped, saprophytic bacterium which was patented by Ananda Mohan Chakrabarty, for the ability of the bacterium to biodegrade oil. P.putida is capable of converting styrene in the oil into the biodegradable plastic which can be effectively used in recycling polystyrene foam in the plastic industries. Methanobacterium as the name suggests are a group of bacteria used to produce biogas like methane and hydrogen gases on degarding cowdung. Rhizobium is symbiotic nitrogen fixing bacteria which can fix atmospheric nitrogen in usable form in the roots of leguminous plants. B.thuringiensis is a bacterium used for its insecticidal property to control specific pests (cotton ball worm) affecting the yield of cotton plant.
