Learning outcomes

The course is designed to deepen the theoretical basis and the criteria for the application of microbial systems to the production of compounds of economic interest, to energy recovery and production, to waste treatment and environmental detoxification. Based on the wealth of information acquired while attending previous classes of microbiology content, students will address issues relating to the properties of microorganisms, both prokaryotes and eukaryotes, including bacteria, archaebacteria, yeasts, filamentous fungi and - in a distinct position because of their non-cell structure – viruses, in relation to potential technological applications. Microorganisms will be mainly analyzed as biological catalysts of specific biosynthetic reactions and/or degradations, carried out either in a confined environments (bioreactors) or in open context, focusing on the actions aimed at controlling and optimizing the processes of interest.
