Course detail

Laboratory classes in biotechnology

FCH-MC_BIO_PAcad. year: 2025/2026

The practical exercise consists of 5 block tasks focused on working with microorganisms used in food and biotechnology, their isolation and identification, monitoring the dynamics of their growth and multiplication and the production of important metabolites, such as antimicrobial substances and selected enzymes. During the practicals, emphasis will be placed on deepening and mastering basic practical skills in the identification, study and cultivation of microorganisms, including the use of molecular diagnostic methods. Attention will also be paid to selected biotechnological procedures and the detection of their efficacy based on the analysis of biologically active substances.

Entry knowledge

The knowledge from the course Microbiology in food industry and biotechnology, Biotechnology I and Biochemistry.

Rules for evaluation and completion of the course

Participation on exercises, elaboration of written report of required content and form.

Aims

The main aim of the course is to introduce students to the techniques of working with biological material in laboratory conditions. It also aims at a better understanding of the theoretical knowledge acquired so far in biotechnology and its connection with other fields such as microbiology, molecular biotechnology, biochemistry, etc. Completion of the course will deepen the theoretical knowledge of students acquired not only in the lectures of Biotechnology, but also in Microbiology for Food Scientists or Biochemistry. Students will acquire practical knowledge of selected biotechnological, microbiological and molecular biotechnological methods used in the food industry to identify microorganisms, detect their secondary or primary metabolites or monitor selected biotechnological processes.
