Eukaryotische Mikroorganismen/Mikroalgen

In the laboratory course the practical skills of the students by applying different methods for the classification and cultivation of eukaryotic microorganisms (e.g. heterotrophic marine dinoflagellates, algae-like peronosporomycetes, lower and higher fungi), for the development of culture conditions, the quantitative and qualitative analysis of cell growth, the extraction of natural substances (e.g. fatty acids, enzymes) and the analytical product identification with chromatographic methods are trained. Herein each student should isolate and determine eukaryotic microorganisms from natural sources, purify one strain and determine contents and activities by using screening techniques. The students work in small teams (2-3 persons) and coordinate the approaches/practical work between the different group members. In this way, the students improve their soft skills in terms of communication and coordination of the work flow. Additionally, the laboratory course will strengthen the students competencies in the interpretation, evaluation and presentation of lab data by summarizing the results in a final report and by an oral presentation at the end of the course. The accompanying seminar intents to train the scientific competencies of the students by searching for and presenting relevant literature focusing on the topics of the practical course.
