a mechanism for the auto-oxidation of reduced phenazine derivatives is proposed where superoxide production occurs in discrete steps in the auto-oxidation of fully reduced pyocyanine whereas for the auto-oxidation of fully reduced phenazine methosulphate , phenazine ethosulphate and 1-methyoxyphenazine methosulphate , the production of superoxide appears masked by the rapid further reduction to hydrogen peroxide .
