Marine Microbes

Lecturers: Gunter Wegener

Content:

The course is designed to explain principles in microbiology including cellular structure, physiology and ecology. It provides an overview about the diversity and function of mircoorganisms in the marine environment and how they catalyse essential processes in the elemental cycling of carbon, nitrogen, phosphorus and sulfur. Specific biogeochemically relevant processes such as aerobic oxidation of ammonium and anaerobic oxidation of methane will be discussed in more detail.

Competences:

At the end of this course the student will be able to:
a) understand general aspects on the cellular structure and function of microorganisms
b) describe principles in microbial physiology in particular the energy metabolism and carbon assimilation
c) discuss the ecological role of relevant microorganisms and their contribution to the marine biogeochemical cycles

Assessment:

Oral exam focusing on all three course topics offered in the module (30 min).

Exam Form:

oral exam
