The students must recognize: the microbial diversity and classification; microbial procaryotic and eucaryotic cell organization, morphology and growth patterns; microbial interactions and role in living systems and biotechnological production.
1 - Introduction to Microbiology
Objectives and history. Insertion of microbial taxonomy in the context of living beings. Major groups of microorganisms, role and importance. Application areas.
2 - Characteristics of different groups of microorganisms
Prokaryotic microorganisms - bacteria and archaebacteria. Eukaryotic microorganisms - fungi and protists (algae and protozoa). Virus - constitution, classification and replication.
3 - Nutrition, growth and reproduction of microorganisms
Nutritional requirements and types. Input of nutrients. Multiplication and death of a microbial population. Generation time and growth rate. Quantitative evaluation of growth. Limiting factors and control. Bacterial metabolism.
4 - Applied Microbiology
