Educational objectives Knowledge and understanding of the biology of microorganisms, their structure, physiology and reproductive mode. Basic microbiological knowledge necessary for the study of specialized microbiology courses in the following years and for the master's degree.
Teaching is designed to allow the learning of microbiological dynamics in natural, biotechnological and clinical settings, with particular attention to the development of critical thinking in the field of the subject.
At the end of the course, the student must be able to recognize the main microbial groups, to associate each group with its main specificities and to understand the potential applications of each microbial group. The student will also have the skills to evaluate the techniques and approaches necessary to recognize and typify various microorganisms.
Prerequisites I sem Biological courses
Teaching methods Lectures, numerical practicals
Other information Discussion with the instructor
Learning verification modality Written and oral exam
