Bioremediation
A.Y. 2025/2026
Learning objectives
Bioremediation is the application of microorganisms to improve environmental quality. These improvements include the treatment of contaminated waters and wastewaters, clean-up of industrial waste streams, and remediation of soils contaminated with hazardous and toxic chemicals.
The course will be composed of two parts: Environmental Microbiology and Biotechnological Remediation and Laboratory of Cell Biology.
The course will enable the students to learn and practice the basic and advanced techniques of manipulation of prokaryotic and eukaryotic cells.
The course will introduce the students to the knowledge of environmental microbiology and of the basic microbiological treatment technologies to clean up contaminated environments. During the course, the students will also learn the basic genetic engineering techniques used to manipulate microorganisms not only for remediation purpose but also to build microbial biosensors to detect the presence of contaminants in the environment (Part 1: Environmental Microbiology and Biotechnological Remediation).
The course will also provide the students with an overview of the techniques used for the manipulation of in vitro cell cultures as models for risk assessment of toxic agents, with a focus on specific cellular functions, including proliferation, viability, survival, migration, invasion, differentiation, adhesion, and angiogenesis (Part 2: Laboratory of cell biology).
The course will consist of a lecture-based theoretical section and a laboratory-based practical section.

Expected learning outcomes
Expected learning outcomes
At the end of the course, the student should have acquired knowledge about the principles of bioremediation and should be able to manipulate prokaryotic and eukaryotic cells in vitro by performing specific cellular and molecular techniques.
Part 1: Environmental Microbiology and Biotechnological Remediation
Upon completing this course, the students should be able to demonstrate an understanding of the basic aspects of environmental microbiology and of the influence of microorganisms on environmental pollution. Moreover, students should demonstrate to have acquired the ability to evaluate when each bioremediation strategy would be most applicable, based on the polluted site characteristics.
Finally, the students will gain capability to exploit the basic molecular techniques to build a bacterial biosensor to reveal environmental pollution.
Part 2: Laboratory of Cell biology
At the end of the course, the student should have acquired a large knowledge about fundamentals of cell culture, novel cell culture technologies, fluorescence-based techniques, methods to assess cell proliferation, viability and survival, methods to assess cell adhesion and migration, transient and stable gene overexpression, other technologies of genetic manipulation.

Course syllabus
Environmental Microbiology and Biotechnological Remediation:
Environmental biotechnology utilizes microorganisms to improve the environmental quality. These improvements include the treatment of contaminated waters and wastewaters, clean up of industrial waste streams, and remediation of soils contaminated with hazardous and toxic chemicals.
This course will introduce the students to the scientific principles of microbiological treatment technologies to clean up contaminated environments and to the basic DNA engineering techniques to manipulate microorganisms for these purposes. Moreover, the students will acquire experience on molecular methods /techniques used to monitor the presence of contaminants by the construction of a microbial biosensor. The course will consist of lecture-based teaching to provide background information on key concepts on bioremediation and in a laboratory-based section where the students will construct and use a microbial biosensor.
The lecture-based section will include the following topics: (1) fundamentals of environmental microbiology, (2) principles of bioremediation of organic contaminants and toxic molecules, (3) engineering strategies for bioremediation and biosensors construction.
Laboratory section
Day 1: Extraction of genomic DNA from suitable bacterial strain and quantification.
Day 2: Amplification of regulative gene and promoter by PCR, check on agarose gel and excision from agarose gel. Enzymatic digestion of fragment DNA.
Day 3: Plasmid DNA extraction (Midiprep) and purification. Enzymatic digestion.
Day 4: DNA fragment/plasmid excision from agarose gel, set up of the ligation mixture and overnight incubation.
Day 5: Competent Escherichia coli cells preparation and transformation. Overnight incubation.
Day 6 (second week): Plasmid preparation (Miniprep) from transformants and screening by restriction analysis.
Day 7: Growth of the reporter E. coli and control strains in the presence of different xenobiotic compounds and samples collection.
Day 8: β-galactosidase assay. Conclusions.
Laboratory of Cell Biology Cell culture techniques are commonly used in cell biology, pharmacology and toxicology. Starting from basic approaches and considerations, this course aims to provide the theoretical and practical skills needed for designing cell culture-based experiments. It will also provide an overview of the technologies available for manipulating the gene expression of cultured cells and integrating this approach into a research project. The lecture-based section will include the following topics: (1) fundamentals of cell culture; (2) novel cell culture technologies; (3) fluorescence-based techniques; (4) methods to assess cell proliferation, viability and survival; (5) methods to assess cell adhesion and migration; (6) transient and stable gene overexpression; (7) other technologies of genetic manipulation. The practical section will include demonstrations on cell culture and manipulation.
