Skrócony opis:

Lectures in Microbiology aim to acquaint students with the world of microorganisms, indicate their role in the most important biological processes on the Earth connected with matter cycling and energy flow in various aquatic and terrestrial ecosystems. Lectures will enhance a better understanding of the importance of microorganisms in the functioning of biocenosis, transformations of biogens, their mutual effect on each other and other living organisms. Studies in microbiology aim to highlight the beneficial and harmful role of microorganisms in nature and indicate strict connections of the microorganism world with the living environment of plants, animals and humans. Knowledge in the field of microbiology is a necessary prerequisite for gaining the skills of practical control of microorganism development and activity, which is crucial for a framer striving to produce good quality crops and protect them against damage due to microorganism activity.
