Type of course

Master level course for biology students. It is mandatory for students admitted to the Molecular environmental biology discipline (prioritized).

The course has a maximum capacity of 12 students.

The course is not available as a singular course.

Course content

The aim of this course is to give a thorough introduction to molecular methods and basic bioinformatics used in modern environmental microbiological research. The course will give a basis for advanced studies in microbial ecology and include practical exercises followed by data analyses including computer analyses of own data sets.

The students will perform fieldwork, isolate DNA and RNA from different types of samples, perform an incubation experiment including gas analyses, perform fluorescent labeling of microorganisms and prepare DNA and RNA samples for qPCR, sequencing and bioinformatics. The laboratory and computer work is running for two weeks and the results are discussed and presented by the students in plenum. In addition comes lectures, colloquiums and seminars.

The students have to write individual laboratory reports shaped as scientific articles. The use of AI will be discussed, but encouraged only for text polishing and minor adjustments, and large errors originating from hallucination and bad commands will count highly negatively in the evaluation. The lectures will be closely connected to the practical problems to be solved in the laboratory and relevant background theory. Selected articles from the scientific curriculum are topics for seminar presented by the students. Curriculum consists of lectures, lab materials and scientific articles.

Objectives of the course
