Course contents:

The following topics are covered both theoretically and practically by lectures and laboratory exercises:

1) Systematics for bacteria, yeast and mould that are used in the food industry.

2) Metabolism, stability / lability and bacteriophage problems of lactic acid bacteria.

3) Production, use, control and maintenance of cultures for fermentation purposes.

4) Use of fungi and yeasts in fermented foods and industrial processes. 

Learning outcome:


On completion of the course the student should have:

  • Knowledge about the use of bacteria, yeasts and moulds in different fermented foods, as well as in industrial processes.


On completion of the course the student should be able to:

  • Identify, characterize and maintain microbial cultures for fermentation purposes.
  • Find scientific literature on relevant topics in books and scientific journals.

General competence

On completion of the course the student should:

  • Understand the relationship between growth, metabolism and product properties in fermenteted products.
Learning activities:
Lectures and laboratory exercises with journals. Excursion to a food fermentation company or the biogas laboratory at NMBU.
