1 semester

A one-week block internship must be completed, for which the contents of the lecture and the internship script are a prerequisite. The internship takes place during the lecture-free periods after the examination period. An internship report will be prepared afterwards

In recent years, the importance of biological process engineering has steadily increased in energy, environmental and process engineering. The use of microorganisms is indispensable in environmental technology (purification of process water, air, etc.), in energy technology (bioethanol and biogas production) as well as in the pharmaceutical and food industries. After successfully completing the module, students will understand the basic biological relationships and processes in microbiological cells and their use in technology.

In bioprocess engineering, microbiology is the basis of all foods produced with organisms.

Contents of the lecture: 1. microorganisms and microbiology 2. macromolecules of the cell 3. cell biology, 4. nutrition and metabolism, general bioenergetics in microorganisms 6. growth of microorganisms 7. types of fermentation 8. use of microorganisms in food technology, environmental technology, energy technology (sewage treatment technology, biogas plants, biofilters, fermentation of organic acids and alcohols, food production, production of biopolymers)

Contents of the practical course: 1. microbiological working methods and sterile techniques, 2. microbiological environmental examinations, determination of microbial counts in the air, water microbial load, 3. microscopy of activated sludge and assessment of sludge quality using indicator organisms, 4. isolation of pure cultures from a mixed culture, Gram staining, 5. Cultivation of microorganisms, determination of growth parameters, 6. fermentation cider production 7. enzyme test systems ADH test for alcohol determination Experiments are carried out by the students in a group work, where they are taught scientific working methods and the experimental results are summarized in a report.

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

Lectures during the semester, practical course in a block week after the exam period.

• Portfolio exam

Basic knowledge of biology, knowledge of organic and inorganic chemistry,

Students who have successfully completed this module have basic knowledge of microbiology and the use of microorganisms in industry. Practical sterile and fermentation techniques can be applied, which are used to cultivate microorganisms in large quantities. Pure cultures can be isolated using selection measures and characterized phylogenetically using indicators. After completing the module, students will be able to use procedures and methods that are used for selected standard problems and will be able to process the results of their investigations in a team, present them in a scientific report and discuss the results critically.

Students can apply and implement their theoretical knowledge of basic biology in practice on microorganisms

In the practical part, you will use a range of standard and some advanced procedures and methods. The measured data is then elaborated and presented in a structured scientific report in order to obtain and process information. The measurement results are then scientifically interpreted and evaluated in context.

Theoretically acquired knowledge is deepened in practical experiments in which the results are scientifically assessed and interpreted in groups.

Students at Osnabrück University of Applied Sciences who have successfully completed this module learn the different methods in groups and can present the measurement results of practical laboratory work scientifically in a well-structured and coherent form. They can also explain and interpret the test results.
