Antifungal activity of TiO2 photocatalysis against Penicillium expansum in vitro and in fruit tests

Role of physical and chemical interactions in the antibacterial behavior of ZnO nanoparticles against E. coli

“…•OH radicals, forming hydrogen peroxide [1,9,17,[32][33][34][35][36][37][38][39]. Therefore, it may be suggested that regarding the ROX effect, hydrogen peroxide and superoxide anion production from ZnO NPs would not produce salient antibacterial effect.…”

Genetic studies of the role of fatty acid and coenzyme A in photocatalytic inactivation of Escherichia coli

“…Matsunaga et al (1985) reported the application of TiO 2 eUV photocatalysis for the inactivation of three different microorganisms: Lactobacillus acidophilus, Saccharomyces cerevisiae and Escherichia coli. Then, a wealth of information has demonstrated the efficacy of photocatalytic inactivation of various microbes, including bacteria (Sunada et al, 1998;Hu et al, 2006;Benabbou et al, 2007), viruses (Lee et al, 1997;Vohra et al, 2006), and fungi and yeasts (Lonnen et al, 2005;Maneerat and Hayata, 2006). To ensure the applicability, many studies focused on the photocatalytic inactivation mechanism.…”

The Testing of TiO2 Photocatalityc Reaction to Inhibit of Botryotinia fuckeliana

“…The antifungal activity of TiO 2 photocatalytic reaction against phytopathogens that might affect postharvest tomatoes and kiwifruit has also been tested (Hur et al, 2005;Maneerat and Hayata, 2006). Furthermore, inactivation of Fusarium oxysporum and Pythium aphanidermatum in hydroponic solution by TiO 2 photocatalytic reaction have been studied (Nakabayashi et al, 1999;Koohakan et al, 2003).…”

“…Titanium dioxide (TiO 2 ) has a photocatalytic reaction under UVA (315 -400 nm) irradiation and shows many excellent effects such as disinfection (Maness et al, 1999;Ibáñez et al, 2003;Kim et al, 2003;Maneerat and Hayata, 2006;Chawengkijwanich & Hayata, 2008) and decomposition (Maneerat et al, 2003), and can be used for a deodorant (Murakami et al, 2004) and water purification (Herreara Melian et al, 2000;Wist et al, 2002), but there are few reports on agricultural crops (Lu et al, 2006). When activated by UVA irradiation, the TiO 2 photocatalytic reaction generates hydroxyl radicals and superoxide ions at the TiO 2 surface.…”
