(syllabus)
The course will take place according to the following breakdown: 1. History of Microbiology (notes): the discovery of the world of micro-organisms and the controversy over spontaneous generation; microorganisms as agents of disease and their role in the transformation of organic matter. 2. Technical basis of microbiological laboratory: the microscope, notes of optical physics; fresh and colorful slides; electron microscopy (transmission and scanning); pure culture and its achievement; general principles of microbial nutrition; preparation culture media, theory and practice of sterilization; controls sterility. 3. Cytology of prokaryotic and eukaryotic cell: general introduction; structure and ultrastructure of the bacterial cell; structure and function of the membrane; transport systems across membrane; cell wall and its chemical composition and characteristics; the wall of Gram + and Gram -; cell wall of archaebacteria and eukaryotes; capsule and the associated virulence; cell movement and structure for movement; chemotaxis, bacterial endospore, structure, function and importance; overview of spores of eukaryotes and the alternation of generation; mitochondria and respiratory function; overview of the arrangement of DNA and cell division. 4. Cell physiology: brief review of cellular chemistry and biochemistry (activation energy, catalysis and enzymes, biological redox reactions, hydrogen and electron transport; phosphate molecules with energy bonds); production of energy in biological systems; glycolysis and similar ways; re-oxidation of NADH: fermentation and respiration; alcoholic and lactic fermentations, aerobic respiration, the tricarboxylic acid cycle and the electron transport system; energy balance of catabolism; notes on anaerobic respiration, biosynthesis of cellular material. 5. Microbial growth of a single cell and a microbial population; measure of growth and related curve; catabolic repression and diauxia; effect of cultivation conditions on microbial growth.
The laboratory practices cover the following topics: 1. The pure culture and its isolation: spreading and crawling, the re-isolation; the enrichment cultures; 2. Microscopy and microscopic observation; observations of fresh samples; simple and differential staining and observations of stained preparations; 3. Cultivation of microorganisms and measurement of microbial growth (direct and cultural counts, dry weight, turbidimetry).
