With the use of enzymes, specific inhibitors, quenchers and scavengers of active oxygen species we found that the two forms responsible for the depolymerizations are hydroxyl radical and singlet oxygen. Both of those active forms are produced by the interaction of superoxide ion with hydrogen peroxide, the latter two being produced by xanthine oxidase.
