Applied Microbiology
A.Y. 2024/2025
Learning objectives
In this course students will acquire basic knowledge of microbiology. The students will learn structure and functions of the prokaryotic cell and will then be confronted with the metabolic and physiological diversity of prokaryotes. Key concepts on genetics will be also offered to students. Overall, these concepts represent tools to understand the applications of microbiology in the medical, pharmaceutical and diagnostic fields as well as in food industry.
Expected learning outcomes
On successful completion of this curse the student will have acquired basic knowledge in microbiology and will know in detail the functioning of the prokaryotic cell. Moreover, the student will become familiar with the applications of microbiology in the medical pharmaceutical and industrial fields.

Assessment methods and Criteria
The verification of learning is represented by a written test; it consists of a series of multiple-choice questions and an exercise, each with a maximum score proportional to the complexity. The final grade is given by the sum of the scores obtained in the individual questions. Time available: 1 hour and 30 minutes.
