| Course abstract | |
| The aim of the study course is provide fundamental knowledge on general and food microbiology. By mastering the characteristics and development of microorganisms, students are able to to determine the usefulness of microorganisms in the technological processes of food production. Students gain knowledge about the impact of different microorganisms on the quality of food products. During laboratory work students learn microorganism detection methods | |
| Learning outcomes and their assessment | |
| After completing the course, the student will have:
Knowledge and understanding of microorganism morphology, physiology, biochemistry, metabolism processes and the external environmental factors which affect them, as well as the relationship between food production processes and quality of food products. Skills to work with microscopy methods and methodology, and to analytically evaluate, explain and have an argumented discussion about the obtained results. Competence to obtain, select and analyse methods and methodology for the determination of microorganisms in food products and their quality evaluation. 1. Knowledge of microorganism morphology, physiology and metabolism and the external environmental factors that affect them – test no. 1 2. Knowledge about microorganism metabolism and the influence of their metabolites on changes of food product quality – test no. 2 3.Understanding and ability to evaluate microbiological safety of food products and their association to the production of food products – test no. 3 |

| Description of the organization and tasks of students’ independent work | |
| Students independently analyse the literature on food microbiology, prepare for knowledge tests, defend the laboratory work by analysing the obtained results and applied methods | |
| Criteria for Evaluating Learning Outcomes | |
| In order to receive a cumulative grade, all tests must be evaluated with at least 7 points (out of 10). If the evaluation is below 7, students will write additional test. | |
