Entry knowledge

Good knowledge of microbiology of yeasts and bacteria including their metabolism, good knowledge of biochemistry. Basic knowledge of cultivation techniques, bioengineering principles of industrial fermentations ( esp. process kinetics, material and energy balance). Basis of sanitation in the fermentation industry.

Rules for evaluation and completion of the course

Students must prepare and successfully defend a credit project in the field of biotechnology. A good knowledge of all the discussed technologies is required for the written test.
Credit: project
Exam: written test

Aims

The aim of the course on Biotechnology I is to give students the main information about the basic principles of biotechnologies, their unit operations and equipment. Biotechnology I contains mainly technologies based on yeast cell – brewing, malting, production of baker´s yeasts and other microbial biomass, production of wine, fermentation production of ethanol and alcoholic beverages.
Acquired knowledge is a basis for process optimization, measurement and process control. Seminar makes link with lectures in terms of integration of knowledge from microbiology, biochemistry, chemical and biochemical engineering.
