Ozone and cold plasma: Emerging oxidation technologies for inactivation of enzymes in fruits, vegetables, and fruit juices
2023, Food ControlCitation Excerpt :Evidence was also observed on the involvement of oxyradicals as mediators in the ozone-mediated inactivation of catalase (Fig. 1). The rate-determining factors of enzyme inactivation by ozone were found to be the ozone concentration, length of exposure time, composition of the exposure medium, and pH (Whiteside & Hassan, 1988). A later study by Lee et al. (2003) revised the enzyme inactivation mechanism with ozone by using ozonized water as a substitute for gaseous ozone.
Intercellular singlet oxygen-mediated bystander signaling triggered by long-lived species of cold atmospheric plasma and plasma-activated medium
2019, Redox BiologyCitation Excerpt :These aspects deserve further experimental analysis. CAP contains molecular species that may cause direct inactivation of tumor cell catalase, such as singlet oxygen [29–31,36] and ozone [47,48]. Furthermore, CAP-derived ozone might generate singlet oxygen after its reaction with amino acids [49,50].
Ozone-induced oxidative modification of plasma fibrin-stabilizing factor
2013, Biochimica et Biophysica Acta - Proteins and ProteomicsCitation Excerpt :Ozone belongs to the family of ROS. Ozone is giving rise to a number of other ROS [37,40,41]. Ozone-induced modification of proteins occurs via free radical mechanism and the mechanism of ozone addition.
Adipokinetic hormone-induced antioxidant response in Spodoptera littoralis
2012, Comparative Biochemistry and Physiology - C Toxicology and PharmacologyCitation Excerpt :Exposure of bacteria to paraquat increased activity of SOD in Escherichia coli (Hassan and Fridovich, 1977), and both CAT and SOD in Xanthomonas, where paraquat was surprisingly much more potent than peroxides in the CAT activation (Loprasert et al., 1996). On the contrary, in vitro studies showed inhibitory effects of ozone, hydrogen peroxides, organic peroxides, superoxide and hydroxyl radicals on catalase and superoxide dismutase activity (Whiteside and Hassan, 1988; Pigeolet et al., 1990; Lee et al., 2003). Distinct activities of CAT and SOD during OS are described also in herbivorous insects after feeding on plant prooxidants; SOD activity was increased while CAT activity was not induced (Lee and Berenbaum, 1989) or even decreased after exposure to quercetin (Pritsos et al., 1988; Ahmad and Pardini, 1990).
