Microbial Biotechnologies Applied to Plant Production
A.Y. 2023/2024
Learning objectives
The course will provide to the students current knowledge on the state of the art and developing perspectives about microbial biotechnologies for plant growth promotion, soil fertility and crop protection. Environmental biotechnologies applied to bioremediation, wastewater treatment and the disposal or valorisation of agricultural waste biomasses will be also outlined. Laboratory lessons will allow students to acquire practical experience on qualitative and quantitative tests for the evaluation of plant growth promoting microorganisms.
Expected learning outcomes
The course will provide basic and analytical knowledge necessary to elaborate and discuss a proper evaluation of potentials and limits of the application of microbial biotechnologies for plant production.

Course syllabus
The teaching program includes the presentation and discussion of the following topics:
-Microbial identification and study of environmental microbial communities (microbial ecology methods)
-Role of microorganisms in soil formation, fertility maintenance and cycle of organic matter. Soil microbiota, rhizosphere, phyllosphere
-Plant-microbe interactions: mycorrhizic and attinorrhizic symbiosis, nitrogen fixation and nitrogen fixing symbiosis. Nodule formation
-Plant Growth Promoting Microorganisms: i) microbial mechanisms of direct plant promotion, biostimulation and biofertilisation, ii) microbial mechanisms of indirect plant promotion, antagonistic microorganisms, iii) plant-microbe interactions and bacteria recruitment from plants. Microbial inoculants: production, quality monitoring, agronomical effects
-Microorganisms associated to insects: primary and secondary symbionts, reproductive manipulators, gut symbionts. Bacillus thuringiensis. Symbiotic control of detrimental insects or vectors of phytopathogens
-Microbial biotechnologies for plant biomass transformation and disposal: anaerobic digestion, sludge treatment, photosynthetic organisms for biofuel production
-Soil bioremediation. Rhizoremediation
