AGR/16 - AGRICULTURAL MICROBIOLOGY
II semestre dal Mar 1, 2016 al Jun 10, 2016.
This Course is designed to analyze both theoretical bases and criteria for the application of microbial systems to the production of compounds of economic interest, the recovery and production of energy from biomass or organic by-products and residues, the treatment of waste, and the environmental bioremediation. Based on the wealth of cognitions acquired while attending previous classes of microbiology content, students will address issues dealing with 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, with reference to their potential technological exploitation. Microorganisms will mainly be considered as biological catalysts with specific biosynthetic properties and/or possibly able to carry out transformation/degradation reactions either in confined environments (bioreactors) or in open contexts. Discussion will focus on the procedures aimed at controlling and optimizing the processes of interest.
