The class has the dual purpose of providing basic and specific knowledge regarding the metabolic activities of microorganisms referred to as pro-technological, spoilage and probiotics associated with major food groups. The laboratory credits will complement the theoretical part providing counting methodologies, isolation and identification of single microbial species or groups in different food matrices.

Structure of the prokaryotic  cell

Nutritional requirements of microorganisms

Reproduction of bacteria: cell division

Bacterial aerobic and anaerobic respiration and fermentation.

Growth strategies in comunity: Biofilm

Moulds and yeasts

D1-Knowledge and  understanding ability: Knowledge of   the microbial importance and role especially in the food context. Understanding the specific words and language of this discipline.

D2-Ability to apply knowledge and understanding: Understanding the role of microorganisms in food production and their impact on food quality.

D3-Independent judgment: Understanding the importance of the presence and development of microorganisms in food both from an economic and public health point of view.

Q4-Communicative ability: Ability to use correctly and appropriately scientific language and specific vocabulary of food microbiology, and to illustrate and communicate orally and in writing the acquired concepts.

D5.Learning capability: 

The student must demonstrate that he / she is able to:

- maintain a contradiction with people of equal preparation and expertise in different themes, regulatory, scientific and procedural;

-illustrate and discuss in groups strategies for the use of microorganisms in the food sector.

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Attendance

Mandatory workshops

Course books

Dehò G., Galli E.   BIOLOGIA DEI MICRORGANISMI  Casa Editrice Ambrosiana (Text used for the general microbiology part)

Farris A.F., Gobetti M., Neviani E., Vincenzini M. MICROBIOLOGIA DEI PRODOTTI ALIMENTARI Casa Editrice Ambrosiana  (Text used for the part relating to food microbiology)

Assessment

The final assessment will be by oral interview.  The purpose of the test is to verify the acquired knowledge and to evaluate the ability to correlate the various topics discussed in the course (descriptors 1 and 2), communication skills (descriptor 4) and the ability to solve practical problems (descriptors 3 and 5). Responses will be judged on the basis of the knowledge of the subject, the display capacity and the language used as the correct and appropriate scientific terminology.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
