Abstract
The white-rot fungus Phlebia ochraceofulva (Bourd. & Galz.) Donk. stra in 75144 actively produced lignin peroxidase (LiP) under nitrogen-limi ted cultivation conditions. Maximal activity was reached during days 6 -8 of growth in bioreactors containing immobilized mycelium and either a low basal concentration of Mn(II) (0.12 ppm) or a 10-fold concentra tion of Mn(II) (1.2 ppm). Laccase activity was also detected in the ex tracellular fluid of P. ochraceofulva, but no Mn-peroxidase (MnP) acti vity was observed with either level of Mn(II). Five lignin peroxidases were purified and partially characterized.
