Initially, the laccase triggers ABTS oxidation that occurs with the formation of radical cation [ABTS.sup.+*] with a correspondence with first peak oxidation [E.sub.pcI], in cyclic voltammetry profile, in approximately + 0.17 V; the second oxidation peak, [E.sub.pcII], represents the oxidation of the radical cation forming the dication ABTS2+ in approximately + 0.73 V (Figure 2).

In the toxicity due to PQ, the PQ dication ([PQ.sup.2+]) accepts an electron from a reductant to form the PQ monocation radical ([PQ.sup.+]), which subsequently reacts rapidly with [O.sub.2] to produce superoxide ([O.sub.2.sup.*-]).
