The main cause of the oxidative stress in bacteria is due to the following reasons, i.e., imbalance of macromolecules changes, cellular and intracellular antioxidant and oxidant concentration which is related to lipids, proteins, and DNA repair enzymes [42]. Enzymes are considered to be the shield of microbes and catalyses Hydrogen peroxide which is the prevailing bactericide (also for spores) and oxidant that is capable of generating chemicals that can oxidize hydroxyl radicals (OH˙) [43]. Peroxidases convert to alcohol and water by reducing hydrogen or organic peroxides.
