Areas of Competence the Course Will Address
The course is obligatory for the M.Sc. Dairy Science specialization and contribute to obtain competance in basic science on classical and molecular characterization of starter and non-starter bacteria, the relevance of starter and non-starter bacteria physiology and genetics in relation to their use in foods.
Competance obtained within applied science:
Comprehend role of starter and non-starter bacteria in fermented dairy products.
Comprehend principles for starter production. Apply principles for species and strain identification of dairy organisms.
Knowledge on most important spoilage and pathogens in dairy products.
Competance obtained within ethics and Values:
Are able to discuss obtained results from project work
Competance in relation to the dairy specialization: Be able to use and evaluate dairy microbial infomation in dairy processes. Understand the principles of starter bacteria as ingrediens in dairy products.
 
Course Objectives
The aim of the course is to give the students a thorough knowledge of primary and secondary starter cultures for dairy products, including the adventious microflora associated with cheese. Through the project work the course will also give the students additional knowledge on microbiological analysis on some organisms. Knowledge of the most important spoilage and patogens in dairy products has also been obtained.
 
Course Contents
The course will be project oriented and the projects will be coordinated with projects from "Cheese Technology" if possible. It is therfore recomended that "Starter and Non-starter cultures for dairy products" and "Cheese Technology" are taken simultaneously.

The cource will contain lectures on primary (Lactic acid bacteria) and secondary (Yeasts, molds, propionibacterium, smear microflora) starter cultures used for production of fermented dairy products. In addition lectures on non-starter lactic acid bacteria and their role in cheese ripening will be covered,as well as pathogenic and spoilage microflora will be covered. Lectures will be concentrated in the first part of the cource.

The projects will contain teoretical and practical parts. They will mainly focus on cheese microflora including primary and secondary starter cultures, non-starter LAB, inhibitory substances and bacteriophages. The basic techniques learned in "Lactic Acid Bacteria Microbiology" will be applied in the practical part.

The colloqia will be related to the projects and will include presentations of the project plan, midterm and final result.

An excursion to a starter company will be included.

 
Teaching And Learning Methods
The course will have a limited number of lectures mainly located in the beginning of the cource. These lectures support the practical projects. In addition a group project containing teoretical and practical parts are included. The project are related to the microbiology of fermented dairy products. In colloqium form the project plan and project results are presented. An excursion to a starter company will be included.
