CY7110 : Applied and Environmental Microbial Chemistry

Organic & Biochemistry
  • The beginnings of microbiology – contributions of Antonie Van Leeuwenhoek, Pasteur, Koch, Ehrlich, Fleming, Wakaman, Winogradsky etc. in three centuries,and microbiology in the twentieth century.
  • The methods of microbiology – pure culture techniques, microbial nutrition principles, construction of culture media, isolation and environment.
  • The relationship between structure and function in bacteria, fungi and viruses.
  • The principles of bacterial classification and phylogeny.
  • Microbial growth and effect of physical and chemical agents in environment viz.
  • pH, temperature, pressure, electromatgnetic radiations, solutes, phenols, alcohols and oxygen relations.
  • The Archaebacteria and their significance.
  • Microbial metabolism – fuelling ractions, biosynthesis, polymerization and assembly.
  • Microbial genetics – transformation, conjugation, transdution, protoplast fusion, genetic recombination.
  • Microorganisms as geochemical agents in mineral transformation, cycles of matter through geological time, biofertilizers, bioleaching of metals.
  • Microbes in industry – fermentation processes for the production of alcohols, organic acids, amino acids, enzymes, vitamins, antibiotics and steroid transformations – “primary and secondary metabolites”.
  • Ouline of roles of microbes in air, soil, water, food, dairy, diseases, waste disposal and recycling.
