A high number of plants face nutrient requirements establishing symbiotic relationships with microorganisms inhabiting the rhizosphere, which is the portion of soil surrounding the roots. A wide range of possible interactions between plants and microorganisms can occur, depending on the plant species, the microbial communities and the presence of nutrient in limiting amounts.

Some microorganisms of the rhizosphere are able to exert biostimulation of plant growth through. Indeed, Plant Growth Promoting (PGP) microorganisms can:

  • facilitate the absorption of nutrients present in the soil by plants (biofertilization);
  • synthesize phyto-hormones able to stimulate plant growth and development (phytostimulation);
  • control the proliferation of harmful and/or pathogenic microorganisms through the production of molecules with antibiotic activity (biocontrol).

The skills and services offered by Bactory in this specific sector concern:

  • Isolation, identification and characterization of bacterial and/or fungal PGP microorganisms;
  • Determination of PGP activities:
    • Production of growth-stimulating plant hormones;
    • Ability to relieve ethylene stress;
    • Production of compounds able to absorb essential elements (mineral ions) and make them available for plants;
    • Phosphate solubilization;
    • Ammonia production;
  • Evaluation of the root colonization efficiency by rhizobia, which are able to convert atmospheric nitrogen into nitrogen containing compounds more bioavailable for plants;
  • Study and identification of biodiversity of mycorrhizae in soils;
  • Evaluation of the ability of mycorrhizae to colonize plants of agricultural and forest interest;
  • Research and development of microbial formulations for the stimulation of crop productivity;
  • Research and development of microbial formulations for the biocontrol of pathogenic microorganisms for crops of agricultural interest.
