Course abstract

Students obtain knowledge about classical microbiology and microbiology of food products. Students give a basic knowledge about structure of microorganism cell, microorganism tacsonomy, properties, growing conditions etc. They receive the information about influence of microorganisms on quality of food products.

Learning outcomes and their assessment

After the course student will have:
Knowledge and understanding of morphology, physiology and biochemistry of microorganisms, about metabolisms and influence of external factors.
Skills to work with microscopy methods and to appraise acquired analytical results.
Competences to choose the methods and methodology for determination of microorganisms in analysed product.

Requirements for awarding credit points

Examination. During the semester, students must write tests, complete and defend all intended laboratory work practicals.

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 accumulative grade, all test must be evaluated with at least 7 points (out of 10). If the evaluation is below 7, students must write additional test.
