By removing another electron from the positive polaron, a positive bipolaron or a dication with charge +2 and no spin are localized over several repeating units.
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.*-]).
Figure 2 denotes the relationship of preme- dication period to the pH metery of group O".
The second oxidation peak is irreversible probably due to the deactivation of the generated dication, which is highly reactive, by the nucleophilic impurities present in the medium.
