Grapevine canes are vine growing byproducts studied for their antimicrobial activities. These properties directly connected to the stilbene content; oligomeric stilbenes being most active. In this study, we propose a chemical process, based on oxidative coupling, using metals increase oligostilbene rate and biological effectivity of cane extract against grapevine pathogens. A total ten compound...

Due to the emergence of antibiotic resistance in pathogenic microorganisms, it is urgent search for producers new antimicrobial metabolites. Actinomycetes are gram-positive mycelial bacteria that produce a large number antibiotics used medicine and agro-industrial complex. Currently, researchers focused on actinomycetes ecological niches such as freshwater marine reservoirs, zones with extreme ...

Nanoparticelle biomimetiche di idrossiapatite drogate con ioni metallici (Cu, Fe, Mg, Zn, K) sono state utilizzate in formulazioni contenenti basse concentrazioni rame (Cu) e zolfo (S) per controllare la peronospora (plasmopara viticola) l'oidio (erysiphe necator) della vite. I formulati stati testati campo sulla varietà vino "Dolcetto" coltivata secondo tecniche agricoltura biologica, loro eff...
