Objectives

The objectives of Molecular Microbiology, must translate the specific skills that are expected to be developed by the students, namely: • Plan, execute and interpret experiments. • Familiarization with routine techniques in microbiology and biology molecular (culture of microorganisms, PCR, cloning, gel electrophoresis of agarose and polyacrylamide, Western blot, sequencing etc.). • Familiarization with databases of genomic information and protein and bioinformatics tools (Blast, ClustalW, Primer3, etc.). • Autonomy in search of scientific literature on a particular topic and using the free tools such as PubMed of NCBI also available in the Virtual Library of UP, in particular the Web of Knowledge. • Develop the capacity of oral and written communication. • Develop the capacity of synthesis and critical thinking.

Learning outcomes and competences

Mastering of routine techniques in Microbiology and Molecular Biology and experimental design. Understanding of the different regulation levels of gene expression  (transcription, translation and post-translation) using case studies.

Working method

Presencial

Program

The Molecular Microbiology syllabus aims at bringing students closer to the research area.

Students will benefit from the material resources used in research, and will have access to the specific skills of different research groups, as well as to the knowledge already built and translated into scientific publications. This approach to a research environment is fundamental to ensure access to resources that otherwise would not be available. The laboratory activities incorporate themes of fundamental research versus applied research in microbiology.

 

The basic organization of genetic information in bacteria, the regulation at the transcription and translation levels and the mechanisms involved will be studied and discussed.

 

To reinforce the acquired knowledge, and from a experimental perspective, emphasis will be given to methods that allow the evaluation of gene expression (e.g. Western blot) and their regulation (ex use of regulatory parts such as promoters and RBSs), using as a case study the expression of a heterologous cytochrome P450 with monooxygenase activity in the model cyanobacterium Synechocystis sp. PCC6803. The advantages of biocatalysis and photobiocatalysis versus chemical synthesis will also be discussed, reflecting current lines of research of  the teachers involved.

 

Finally, the program will include a component dedicated to the isolation of bacteriophages from environmental samples and methodologies used in the study of the diversity of natural microbial communities, as well as in the comparison of bacterial isolates, in particular Lactococcus garvieae isolates, which will be compared by "Pulsed Field Gel Electrophoresis".
