The course will provide to the students current knowledge about the state of the art and developing perspectives about microbial biotechnologies in promotion of plant growth and soil fertility. Environmental biotechnologies applied to the disposal of agricultural waste biomasses will be also outlined.
Expected learning outcomes
The course will provide knowledge tools for the evaluation of potentials and limits of the application of microbial biotechnologies for plant production.
-Microbial identification and study of environmental microbial communities; Microbial ecology methods: molecular microbial ecology -Role of microorganisms in soil formation, fertility maintenance and cycle of organic matter. Soil microbiota, rhizosphere, phyllosphere -Association between plants and microorganisms: mycorrhizic and attinorrhizic simbiosis, nitrogen fixiation and nitrogen fixing simbiosis. Nodule formation -Plant Growth Promoting Bacteria: i) microbial mechanisms of direct plant promotion, biostimulation and biofertilisation, ii) microbial mechanisms of indirect plant promotion, antagonistic microorganisms. Microbial inoculants: production, field application, agronomical effects -Microorganisms associated to insects. Symbiotic control of detrimental insects or vectors of phytopathologies -Microbial biotechnologies for plant biomass transformation and disposal: anaerobic digestion, sludge treatment. -Soil bioremediation. Rhizoremediation
