Classification and nomenclature of microorganisms- 15hrs
Classification schemes of a living organism, differential characteristics of prokaryotic and eukaryotic microorganism. The general principle of nomenclature, three and five-kingdom concepts, a basic understanding of the classification of bacteria, viruses, fungi and protozoa, classification, nomenclature and characterization of bacteria according to Bergey’s Manual of Systematic Bacteriology
Harmful and beneficial microorganism; applied microbiology (medical, public health, agricultural, food, microbial biotechnology, environmental, industrial, pharmaceutical microbiology)
Morphology of bacteria– 10hrs
Structure of bacteria, morphology and fine structure of cell organelles, differences between gram-negative and gram-positive bacteria
Growth and physiology of bacteria- 8hrs
Nutritional types of bacteria (photolithotrophic, chemolithotrophic, photoorganotrophic, chemoorganotrophic), entry of nutrients, passive and active transport, bacterial growth, growth curve, factors affecting the growth
Isolation, enumeration, and culture of bacteria- 10hrs
Types of bacteriological culture medium, techniques for isolation and enumeration of bacteria (streak plate technique, pour plate technique, spread plate technique, membrane filtration, most probable number method, direct microscopic count), biochemical tests of bacteria, methods of the culture of aerobic and anaerobic bacteria, culture preservation methods
Introduction to metabolism, regulation, and energy involved in glycolysis (Embden Mayerhoff Paranas pathway), glycogenesis, glycogenolysis, TCA cycle, pentose phosphate pathway, Entner Doudoroff’s pathway, phosphoketolase pathway, fermentative pathways, and electron transport system
Microbial genetics- 15hrs
Structure and function of prokaryotic DNA, genetic code, plasmids, concepts of bacterial genetics and role of RNA & DNA; bacterial recombination (transformation, conjugation, and transduction), types and importance of mutation
Microscopy and different techniques of handling of microorganisms- 8hrs
Microscopes (light, stereo, darkfield, phase contrast, electron, fluorescence), types of staining and nature of dyes/stains, different types of staining methods for microorganisms, aseptic techniques in microbiology
Techniques in control of microorganisms 12hrs
