(syllabus)
Physiology of microbial growth, biofilm growth and control of biofilm formation in soils and in the rhizosphere. Bacterial metabolism: aerobic and anaerobic respiration, fermentation. Nutritional types. Microbial ecology of rhizopheric soil: microbial rhizospheric ratio, selective microbial enrichment for crop rotation. Microbial selection of zymogen. Microrganisms and biogeochemical cycling of elements: nitrifiers, diazotrophic bacteria, denitrifiers (nitrogen fixing bacteria), ammonium producing microorganisms. Microbial ecology of decomposition, humus formation and mineralization of soil organic matter (SOM). Priming of SOM and r/K co-metabolic effects. Sustainable agronomic biostimulation of soil and microbiome in rhizospheric habitats by mean of organic farming, organic amendments and soil tillage. Microrganisms for sustainable agriculture and environmental management: arbuscular mycorrhizae (Glomus spp.); plant growth promoting rhizobacteria (PGPR and Probiotic bacteria). Relevant phenotypic traits for PGPR and plant inocula application: rhizosphere competence, production of auxin-like compounds, P solubilization, Iron chelation, production of bacteriocins. PGPR as facultative endophytes: Azospirillum spp., Burkholderia spp., Pseudomonas spp. Biostimulants and microbial biofertilizers for phytostimulation. Application of PGPR and mycorrhizae in sustainable cropping systems, in the intercropping and horticulture. Nitrogen fixation in free living bacteria and by Rhizobium-Leguminosae symbiosis. Rhizobial biology and ecology in free living state and as symbionts: nodules formation and nitrogen fixation. Management of crop systems and effects of the accessions on rhizobial activity. Strain isolation by means of plants as host trap and management of rhizobial effectiveness in isolates for inocula application: edaphic adaptation of symbiosis (cross row technique). Production and co-formulation of rhizobial inocula for commercial application. Microbial spoliage of silage and bacterial inocula in food safety. Composting of plant biomass and methanogenic microbioma in soil and for biogas production from waste. Basic knowledges for bacterial characterization and microbial monitoring in soil and rhizosphere.
