Article Title: Photocatalytic Inactivation of Plant Pathogenic Bacteria Using TiO 2 Nanoparticles Prepared Hydrothermally

doi: 10.3390/nano10091730

Figure Lengend Snippet: Antibacterial activity of A310C and P25 TiO 2 photocatalysts against Xanthomonas arboricola pv. juglandis , Allorhizobium vitis , Erwinia amylovora , and Pseudomonas syringae under UV-A irradiation. The concentration of aqueous TiO 2 dispersions was 0.5 mg/mL. Before UV-A irradiation, dispersions containing bacteria were kept in the dark for 15 min.

Article Snippet: For the pathogen inactivation study, four Gram-negative bacterium species such as the ATCC 49946 strain Erwinia amylovora (American Type Culture Collection, Manassas, VA, USA), the DSMZ 1049 strain Xanthomonas arboricola pv. juglandis (DSMZ-German Collection of Microorganisms and Cell Cultures, Braunschweig, Germany), the DC3000 strain Pseudomonas syringae pv. tomato and the Allorhizobium vitis isolates were used.

Live/Dead BacLight viability results for (O) E. coli D21, (0) E. coli O157:H7, and (4) E. faecalis 29212, adhered onto (a) a negatively charged surface (bare glass slide), and (b) a positively charged surface (10% APTES-coated glass slide). The error bars indicate standard deviations.
