Oxygen radicals, nitric oxide, and peroxynitrite: Redox pathways in molecular medicine (2018, background): “For example, O•− 2 formation rates by different cell types ranging from bacteria (117) to vascular endothelial cells (33) are on the order of micromolar per second and largely increase during the disruption of redox homeostasis or NADPH oxidase activation in inflammatory cells.”

Function and biogenesis of iron–sulphur proteins (2009, background): “The switch between the activating and repressed states depends on the presence or absence of an Fe–S cluster (FNR or IscR) or the redox state of the [2Fe–2S] cluster present in Sox”
Antimicrobial strategies centered around reactive oxygen species--bactericidal antibiotics, photodynamic therapy, and beyond. (2013, background): “coli) which can grow in an anaerobic environment, has been possible to investigate on the effect of oxygen introduction in mutants lacking oxidative defense (Imlay, 2008).”
Correlation between intraluminal oxygen gradient and radial partitioning of intestinal microbiota. (2014, background): “Survival of oxygen-tolerant bacteria requires the expression of reactive oxygen species–detoxifying enzymes, such as catalases, peroxidases, and superoxide dismutases.(38) Catalase activity in the 52 genera (Supplementary Table 1) was found to be expressed more commonly in the mucosally associated m”
Neutrophils to the ROScue: Mechanisms of NADPH Oxidase Activation and Bacterial Resistance (2017, background): “Detoxification and Scavenging of ROS A number of bacterial enzymes, including superoxide dismutases (SODs), catalases, and peroxiredoxins, are utilized to transform ROS into less toxic products (Imlay, 2008).”
Proline Mechanisms of Stress Survival (2013, background): “All these are important antioxidant enzymes (52, 87) and in plants, the ASC-GSH cycle is especially critical for mitigating ROS (87).”
Resistance and survival strategies of Salmonella enterica to environmental stresses (2012, background): “These compounds react strongly with organicmolecules causing damage to nucleic acids, proteins, lipids, and carbohydrates (Cabiscol et al., 2000; Farr & Kogoma, 1991; Imlay, 2008), and without protective mechanisms, bacterial cells would quickly succumb to an accumulation of oxidative damage.”

Biofilm-Related Infections: Bridging the Gap between Clinical Management and Fundamental Aspects of Recalcitrance toward Antibiotics (2014, background): “Oxidative stress defense includes all bacterial mechanisms involved in protection against inadvertent by-products of aerobic metabolism, such as superoxide (O2 ) and hydrogen peroxide (H2O2), which are partially reduced oxygen species (146).”
Biphasic Dose Response in Low Level Light Therapy (2009, background): “Hydrogen peroxide is often used to kill cells in vitro (Imlay 2008).”
