Objectives of the Course
Prokaryotes can be found almost everywhere including aerobic to anaerobic, light and dark, low to high pressure, low to high salt concentration and extremes of acidity and alkalinity. As a result of this, prokaryotic microorganisms exhibited incredible diversity regarding their metabolism and physiology. Some physiologies, e.g. lithotrophy, nitrification and nitrogen fixation are only found in certain groups of prokaryotes. The aim of this course is also to provide a general overview of metabolic diversity of different groups of prokaryotes.
