ENZYMATIC SYSTEMS FOR GENERATING ACTIVE OXYGEN SPECIES FOR REACTING WITH OTHER PRECURSORS TO OBTAIN OXIDATION AND/OR BLEACHING

摘要

The invention relates to oxidation and bleaching systems consisting of: A) a component that enzymatically generates peroxide or superoxide or another reactive oxygen species (ROS), which slowly and continuously provides said (ROS) and B) a special precursor component, which is either formed enzymatically or represents an oxidizable compound or a reactive compound in relation to (A). The special precursor component in (B) consists of either: 1) special compounds that can release NO, NO?+ or NO-¿ enzymatically or in situ, which together with (A) form reactive nitrogen species (RNS), such as e.g. peroxynitrite or the corresponding protonated acidic form or 2) dicyclopentadienyl transition metal complexes, which can activate the peroxide provided by (A), or 3) special organosulphonic acids or activated sulphite, which can generate e.g. dioxiranes in conjunction with (A) and ketones.
