Inactivation efficacy of soft rot Pectobacteriaceae from glass sphere models with the use of DBD as the NTAPP source. Percentage reductions in the amount of colony-forming units (CFU) per milliliter of Ringer buffer were shown. Either 0.5, 0.05 or 0.005 McF bacterial suspension had been used for inoculating sterile model glass spheres. Means ± standard errors are depicted. The experiment was performed in triplicate with three technical replicates each. No statistically significant differences between groups were observed (Kruskal-Wallis test followed by a post-hoc analysis applying Fisher’s least significant difference criterion with Bonferroni correction at p < 0.05). D. solani IFB0099, P. atrosepticum IFB5103, and P. carotovorum IFB5118 strains were used. DBD—dielectric barrier discharge. NTAPP—non-thermal atmospheric pressure plasma. McF—McFarland scale. SRP—Soft rot Pectobacteriaceae.
