Basic taxonomy of the marine microorganisms 3 h theory Prokaryotes (Archea, Bacteria an Cyanobacteria) and Eukaryotes (Algae, fungi, Protozoa). Virus and plasmids Number and distribution 5 h theory 9 h practice Influence of the environmental factors on the microbial life; Microbiological methods of study: sampling (seawater, sediments, organisms), microscopic examination, culturing techniques, direct counts, methods for biomass determination Role of the microorganisms in the sea 5 h theory 2 h practice Primary production, secondary production, microbial chain, microbial loop Neutral, positive and negative relationships between microorganisms and other marine organisms too. Cycling of elements 4 theory 5 h practice Cycle of Carbon, nitrogen, sulphur, phosphorus and other. Interactions of cycles. Marine Pollution and Microorganisms 2 h theory Pollution bioindicator bacteria, role of the microorganisms in the selfdepuration of the sea Microbial life in the extreme environments 2 h theory Hydrothermal vents, deep-sea, brackish environments. Methodological approach; taxonomy and activity of the extreme microbiota.
