Fig. 5From: Oxidation of a non-phenolic lignin model compound by two Irpex lacteus manganese peroxidases: evidence for implication of carboxylate and radicalsThe effect of enzyme loading (a) and superoxide dismutase (b) on the oxidation of veratryl alcohol by IlMnP1 and IlMnP2 in the malonate buffer (50 mM, pH 5.0) at 30 °C for 48 h with 1 mM Mn2+. Control VA was treated without any enzyme in the malonate buffer (50 mM, pH 5.0) with 1 mM Mn2+ Back to article page
