Paragraph based Questions : Read the paragraph and answer the, questions given below: Sulphuric acid is present in the acid rain and materials coming out of mines . You know that erosion of metals present in statues, bridges and buildings occurs due to it. Sulphuric acid is a source of energy for some species of bacteria like Acidophilum spp. and Acidobacillus ferrooxidans Hence. these bacteria can control the soil pollution occurring due to acid rain water soluble salts of uranium are present in the wastes produced during electroplating and in effluent released in the environment from the atomic energy Plant. Geobacter convert these salts of yranium into insoluble salts and thereby prevent those salts from mixing with groundwater sources. Which bacteria prevent these salts from mixing with ground water by converting them into insoluble salts?
