The use of a hydrogen peroxide-stat for controlling the
hydrogen peroxide concentration has been demonstrated for the chloroperoxidase catalyzed
oxidation of indole. It has been shown that in tert-butyl alcohol/water mixtures the oxidation
can be effectively controlled by a hydrogen peroxide-stat. In this medium chloroperoxidase was
stabilized towards oxidative destruction as long as indole was present in the reaction mixture
but inactivation occurred in the absence of a reductant. In contrast with the results with tert-
butyl alcohol/water mixtures chloroperoxidase was inactivated in water by hydrogen peroxide even
when indole was present in the reaction mixture and the oxidant concentration was as low as 30 mu
