Annotation -
The aim of the course is to introduce the student to traditional food and other disciplines in which the use of a microbial agent is necessary to obtain the final product. These industries include ethanol production, winemaking, yeast and feed biomass production, organic acid production (vinegar, citric and lactic acid), amino acid, vitamin and other substance production. The main components of the overview of each technology are substrate characterisation and processing, microbial agent physiology, the microbial process itself, product separation and waste management.

Teaching methods -

Students are introduced to new material through lectures. At the same time, students are encouraged to discuss the topics and actively ask questions.

Students are encouraged to understand the continuity of the individual unit operations and to be able to describe the entire production scheme of each process.

Teaching is enriched through an invited lecture by a practitioner.

Requirements to the exam -

The examination is written test. The correct answer to a question may include multiple choices. One third of the test requires drawing a diagram of the selected technology in the form of successive unit operations.

The result of the test can be changed by oral examination if the student wishes.

Learning outcomes -

Students will be able to:

  • structure the food biotechnology process as a sequence of unit operations from raw material processing through the actual process to product separation and purification
  • describe the role of a biotechnological agent (usually a microorganism) in food biotechnologies based on knowledge of the metabolism of individual producers
  • describe and present examples of how the biotechnological process proceeds from a bioengineering perspective (batch, fed-batch, continuous, semi-continuous, with immobilized microorganisms, etc.)
  • list and present examples of separation processes suitable for the separation and preservation of microbial biomass
  • describe the separation and purification processes used according to the desired product and its degree of purity
