Systems for oxidation or bleaching, especially of pulp, comprise a component enzymatically generating peroxide, superoxide or other reactive oxygen species, and a precursor formed enzymatically, or is oxidizably reactive
A system for oxidation or bleaching comprises components slowly and continuously enzymatically generating peroxide, superoxide or other reactive oxygen species (ROS), and a specified precursor which is either formed enzymatically or is an oxidizable or (A)-reactable compound. Oxidation or bleaching systems, comprising: (a) components slowly and continuously enzymatically generating peroxide, superoxide or other reactive oxygen species (ROS); and (b) a precursor which is either formed enzymatically or is an oxidizable or (a)-reactable compound comprising either: (i) compounds which enzymatically or in-situ set free NO, NO+ or NO- which react with (a) to form reactive nitrogen species (RNS) (e.g. peroxynitrites or the corresponding protonated acids); (ii) dicyclopentadienyl-transition metal complexes which can activate peroxides produced by (a); or (iii) organosulfonic acids or activated sulfites which can be generated in association with (a) and ketones, e.g. dioxiranes.
