Programme

The Environmental Microbiology course aims to provide an in-depth analysis of the fundamental role of microorganisms in global ecosystems, focusing on the dynamics regulating their spatial distribution and the complex biological interactions they establish with the surrounding environment. A central part of the curriculum is dedicated to studying the effects of environmental perturbations, both natural and driven by anthropogenic impacts, examining how these stressors alter the structure, taxonomic composition, and vital functions of microbial communities.In this context, significant emphasis is placed on the adaptation capacity of microorganisms and their functional responses to contamination. The course explores the biological mechanisms underlying ecosystem resilience, which are crucial concepts today for biodiversity conservation and proper environmental management.Finally, the program delves into modern molecular methodologies applied to bioremediation processes. Through the study of advanced molecular biology techniques and culture-independent approaches, students learn how to monitor and exploit the metabolic potential of indigenous microbial consortia to degrade pollutants and restore contaminated sites.

Attendance

Attendance at theoretical lectures is optional, although highly recommended for optimal learning. Conversely, given the applied and methodological nature of the subject, attendance at the 3-4 practical and laboratory sessions held at the IRSA-CNR laboratories in Montelibretti (RM1 Research Area) is mandatory. To acquire the necessary skills for correct environmental sampling and molecular analysis, participation in at least 75% of these practical sessions is required.

Type of evaluation

The final exam consists of an oral examination designed to verify the effective achievement of the expected learning outcomes, and it is divided into two closely integrated phases. The first part requires the student to deliver a short presentation, supported by slides, focusing on the critical analysis of an international scientific article previously agreed upon with the professor. This task, aimed at assessing communication skills, the use of appropriate terminology, and the capacity to convey advanced knowledge in the field, can also be completed as an in-progress assignment during the course; this approach helps stimulate active debate and constructive discussion among peers. The second part consists of an in-depth interview aimed at evaluating the student's theoretical and methodological mastery of the subject. During this interview, the student's knowledge and understanding of the essential role played by microorganisms in the evolution and remodeling of natural and anthropogenic environments, the impact of biotic and abiotic factors on microbial communities, and the genome plasticity of bacteria and archaea will be verified. Furthermore, the student's ability to apply and critically analyze microbial ecology methodologies to assess the presence and metabolic activity of microorganisms within various environmental matrices will also be evaluated.The final grade is expressed out of thirty (up to a maximum of 30/30) and is determined by combining the scores of both parts. The first part, regarding the presentation of the scientific article, accounts for 30% of the overall evaluation and allows students to score up to a maximum of 9 points; in-depth questions will be asked during the presentation, and an outstanding performance accompanied by relevant answers will provide a bonus toward the final honors (lode). The second part, focused on the oral examination of the contents covered during lectures and practical sessions, accounts for the remaining 70% and allows students to achieve up to a maximum of 21 points. In this case as well, precise and rigorous answers demonstrating a solid and thorough understanding of the subject will allow students to aim for the final honors (lode).
