(Pre-requisites: MCB 102 & either MCB 201 or MCB 202)

Nature of the soil and distribution of soil microorganisms. Methods used in determining the types and numbers of microorganisms in the soil. Biodegradation of organic matters, starch, pectins, cellulose etc. Microbial mineralization/ conversion of minerals (C, N, S, and P) and pesticides. Nitrogen fixation. Mycorrhizae and other plant – microbe associations / interactions in the soil. Nature and forms of soil pollution i.e. polychlorinated biphenyls (PCB), plastics, pesticides, dioxins, heavy metals, radionuclides and their transformations/ degradation in soil. Bioremediation in soil – approaches and techniques. Contributions of soil based human activity i.e. agriculture, mining, (bioleaching) etc., to climate change. Methylotrophy, Acid rain, green house effects. Use of microorganism in mineral extraction. Plant growth promoting microorganisms and biofertilizers.
