The course provides basic knowledge on microbial cytology and metabolism, as well as on methodologies to study microorganisms. These informations are applied to microbial processes involved in environmental bioremediation, in soil biogeochemical cycles, in plant root interactions.
Expected learning outcomes
Knowledge on the structure and physiology of microbial cells. Practical skills of the principal techniques used in the bacteriology laboratory. Application of microorganisms in environmental bioremediation and in the promotion of plant growth.
Prokaryotic and eukaryotic cell organization. Morphology an cytology of prokaryotes. Spore formation. Microbial taxonomy. Bacterial growth: environmental factors, cultivation of bacteria, sterilization. Methods for the determination of bacterial growth. Microbial nutrition. Microbial metabolism: gaining energy for biosynthetic purposes, aerobic and anaerobic respiration, fermentation, photosynthesis. Regulation of metabolic pathways. Microbial genetics. Bacteria at work: water treatment plants, biodegradation of organic compounds in environmental bioremediation, heavy metal resistance. Bacterial metabolisms of Arsenic. Soil as microbial ecosystem: role of bacteria in biogeochemical cycles of carbon and nitrogen. The composting process from a microbiological perspective. Plant roots and microbes interaction: plant growth promotion, symbiosis process of nitrogen fixation, mycorrhizae, lichens. Laboratory practical classes are held during the course.
