The syllabuses were designed in order to meet the above objectives and develop the competencies assigned. These syllabuses aim to acquire basic knowledge about the biology of microorganisms in the environment, including in foodstuffs.
The lactic acid bacteria. The bifidobacteria. The importante of intestinal bacterial flora in host health.
Probiotics, prebiotics, symbiotics and metabiotics.
Microbiology of yogurt, kefir, cheese, bread, wine and beer. Technological and microbial processes. Traditional and alternative methods.
Pathogenic bacteria in food. The presence of Listeria monocytogenes, Staphylococcus aureus, Clostridium perfringens and C. botulinum, Bacillus cereus, Brucella, Yersinia enterocolitica, and Campylobacter. Reservoirs in the environment, toxins, contamination and growth in foods, clinical data and public health.
Evaluation of the microbiological quality of plant products. Indicator, index and surrogate microrganisms. FoodNet CANADA - The Canadian integrated national system of food microbiological surveillance.
Practical classes
Microbiology of the yogurt. Levels and diversity of lactic acid bacteria in Portuguese commercial brands.
Microbiology of the kefir. Observation, characterization and quantification of bacteria and yeasts present in a brand of kefir.

Lectures are given interactively with students.
In practical classes, students carry out themselves the experiments. The results are discussed at the end of each experiment. Students have at their disposal a guide to practical work, with the description of all experiences, and references to support key experiences.
The web based platform SIGARRA is used to provided documents needed for the theoretical and practical classes.
