Prerequisites: To take the exam it is mandatory to have obtained credits for the following units of the first year: mathematics, general and inorganic chemistry with elements of physical chemistry, organic and biological chemistry, biology and the following specific prerequisites: general microbiology, transformation technologies of products of plant origin, transformation technologies of products of animal origin.
Target skills and knowledge: The aim of the course is to provide basic and practical elements for a good knowledge of the role of microorganisms, yeast and bacteria, in the production of fermented foods. The technological, functional and safety properties that these microorganisms should possess in order to be used in the production of fermented foods of animal origin (yogurt and other fermented milks, cheese, fermented meat products) and of vegetable origin (wine, beer,bread bakery products , sourdoughs, olives, sauerkraut) will be examined. The course will also consider factors influencing microbial technological traits and new potential applications that include microorganisms.The part relating to food of plant origin will be treated by Prof. Viviana Corich, that relating to food of animal origin by prof. Angiolella Lombardi
Examination methods: The exam consists of two tests: an oral test (prof. Viviana Corich) and a written test (prof. Angiolella Lombardi)
Assessment criteria: Students are expected to show both thorough understanding of the concepts taught and ability to apply the knowledge in practical situations related to food transformation.
Course unit contents: 1st credit: characteristics of the yeast cell, wall, organelles, physiological and molecular mechanisms of reproduction (budding and sporulation).
2nd credit: yeast taxonomy, taxonomical evolution of the genus Saccharomyces and technological implication, description of the main taxonomic groups with particular emphasis on those involved in food production.
3rd credit: yeasts in wine-making, brewing and bakery, characteristics of technological substrates of growth and influence of the production technologies, primary and second fermentations.
4th credit: general concepts on yeast sugar metabolism, alcoholic fermentation, respiration, control of the energy metabolism during technological processes, formation of secondary products, production of flavors.
5th credit: general concepts on yeast nitrogen metabolism, sulfur aminoacids metabolism, aromatic compounds and off-flavors.
6th credit: control of alcoholic fermentation, environmental and nutritional aspects, growth and fermentation kinetics, yeast ecology, yeast starter culture production and use.

7th credit: taxonomy, safety and general characteristics of lactic acid bacteria, methods for their identification.
8th credit: metabolic properties of industrial interest, sugar metabolism, protein metabolism, citrate fermentation, production of bioamines, biopeptides, polysaccharides, role of lactic acid bacteria in the production of fermented milk and cheese, natural starter cultures and selected commercial starter cultures.
9th credit: non starter lactic acid bacteria and their role in cheese ripening, non lactic microbial cultures in cheese production, undesirable fermentations in cheese, bacteriophages in the dairy industry and methods of control and prevention.
10th credit: properties, examples of application, regulation of probiotics, Protective cultures and their application in the food industry, the role of lactic acid bacteria, coagulase negative staphylococci and moulds in fermented meat products, other fermented foods (sourdoughs, fermented vegetable).
Planned learning activities and teaching methods: The course is composed of regular lectures in the classroom supported by the use of slides that are then made available to the students. Moreover recent scientific papers are discussed in order to evaluate innovative potential applications that include microorganisms. A Field trip to wineries/breweries is included.
Additional notes about suggested reading: The slides used for class are made available to students a few days later. Slides, scientifica paper and other texts will be available on the following website (Moodle Platform).
