    D) i and iii

    Correct Answer: A

    Solution :

    Scientists have found three new strains of oil-degrading bacteria in Kochi, Kerala. Earlier, laboratory tests of these new strains conducted were successful. The field trials will be conducted by the Malabar Botanical Garden and Institute of Plant Sciences (MBGIPS), Kozhikode and Bharat Petroleum Corporation Limited (BPCL). The study will allow the development of bioremediation agents to clean up petroleum pollutants from the environment. Enzymes in oil-degrading bacteria (microorganisms) can degrade and utilise hydrocarbons as a source of carbon and energy. Scientists from successfully isolated key hydrocarbon-degrading enzyme produced by the bacteria. The three new strains isolated by MBGIPS include two species of Burkholderia and one species of Pseudomonas.
