Low Temperature Plasma Strategies for Xylella fastidiosa Inactivation

The quarantine bacterium Xylella fastidiosa was first detected in Salento (Apulia, Italy) 2013 and caused severe symptoms olives, leading to plant death. disease, named Olive Quick Decline Syndrome (OQDS), is by the strain “De Donno” ST53 of subspecies pauca this (XfDD), which spread insect Philaenus spumarius. epidemic poses a serious threat agricultural economy landscape, as X. infects several species there yet no recognized solution. Research on OQDS focused finding strategies control its or mitigate symptoms. As perspective solution, we investigated efficacy low-temperature plasma plasma-activated water kill bacterial cells. Experiments were conducted vitro test biocidal effect direct application Surface Dielectric Barrier Discharge (SDBD) bacteria cells Plasma Activated Water (PAW). PAW activity tested possible agent that can move freely xylem network paving way strategy infected plants. results showed high decontamination rate even for XfDD embedded biofilms grown solid media complete inactivation liquid culture medium.
