Bacteriology
This paper will enable students: • To have an idea about different aspects of applied microbiology • To study about bacterial growth and factors affecting it. • To learn staining techniques and preservation of microbes • To learn aseptic techniques • To learn the different types of microbiological media
Microbiology as a field of biology, a brief idea of some applied areas of microbiology: medical microbiology, aquatic, aero, food, agriculture, industrial and geochemical microbiology
Definition of growth, rate of growth, generation time, growth curve, measurement of population growth, batch culture, continuous culture and synchronous growth. Factors affecting growth. - Temperature, pH, oxygen, water availability.
Physical agents- Moist heat, dry heat, filtration, radiation. Chemicals as antimicrobial agents major groups of disinfectants, antiseptics and chemical sterilants.
Microbiological media, Physical states and chemical content of media, general purpose and special purpose media. Nutritional classification of Microorganisms. Isolation techniques (Streak plate, pour plate and spread plate method).
Preparation of microorganisms for light microscopy- wet mount and hanging drop technique. Staining techniques- simple staining, differential staining (Gram’s staining, acid fast staining, endospore staining). Special staining (capsule staining and flagella staining). Preservation of microorganisms by sub culturing, overlaying cultures with mineral oil, lyophilization, use of liquid nitrogen.
