The contents aims to help students understand the history, biology, and growth and control of microorganisms. Beginners of the course are rightly exposed to the foundation of microbiology, which would lead them towards progressive advancement of the subject. Unit 1: Scope of microbiology, Ancient microbiology - Refutation of a biogenesis: Discovery of penicillin: Discovery of vaccination: One-gene one-enzyme hypothesis, Contribution of scientists – Leeuwenhoeck, Edward Jenner, Alexander Fleming, Joseph Lister, Robert Koch, Louis Pasteur, Hargobind Khorrana. Modern Microbiology: Landmark achievements in 20th century. Microbial taxonomy - Definition and systematics, Nomenclatural rules and identification. Haeckel’s three kingdom classification, Whittaker’s five kingdom approach - Woese domain system. Major characteristics used in taxonomy: Morphological, physiological and metabolic, genetic and molecular taxonomy. Bergey’s Classification of bacteria. Unit 2: Differences between prokaryotic and eukaryotic cell. Biology of bacteria - cell structure, size, shape, arrangement membrane, cell wall, cytoplasmic inclusions, mesosomes, flagella and motility, slime, glycocalyx, capsule, pili, chemotaxis, endospore - biology of fungi, structure, physiology and classification – biology of yeast – reproduction - virus (bacteriophages) structure, life cycle (lytic and lysogenic) – biology of algae – mycoplasma – prions. Unit 3: Microbial nutrition: Microbial nutrient requirements, macro-nutrients, micro-elements, growth factors, sources of nutrients, nutritional classification of bacteria: phototroph, chemotroph, autotroph, heterotroph, photoautotroph, photoheterotroph, chemoautotroph, chemoheterotroph – nutritional patterns of pathogens – saprophytes – auxotroph. Unit 4: Extremophiles: Diversity of microorganisms of arctic, antarctic and hydrothermal vents – Archaeal biology - acidophile, alkaliphile, anaerobe, cryptoendolith, halophile, hyperthermophile, hypolith, lithoautotroph, metal-tolerant microbes, oligotroph, osmophile, piezophile, polyextremophile, psychrophile/cryophile, radio-resistant, thermophile, thermoacidophile, xerophile – mechanism of extremophiles. Unit 5: Cultivation and control of microbes: Types of growth media (natural, synthetic, complex, enriched, selective- definition with examples), pure culture methods (streak plate, spread plate, pour plate, stab culture, slant culture). Anaerobic (thioglycollate, anaerobic chamber, Robertson’s media, microaerophilic), liquid shake culture of aerobic bacteria, Control of microbes - sterilisation, disinfection, antiseptic, tyndalization, pasteurization: physical - dry heat, moist heat, UV light, ionizing radiation, filtration, HEPA filter, chemical methods.

MSc Microbiology: Semester 1 CELL & MOLECULAR BIOLOGY Course Code: CMB102 Total Number of Credits: 03 Cell and Molecular Biology aims to introduce the fundamentals and basic biology of life. The contents will help students understand the features and differences between a prokaryotic and eukaryotic cell. It will elaborate the central dogma of the cell i.e., gene expression viz. transcription and translation across both prokaryotes and eukaryotes.
