摘要：

The production of manganese-dependent peroxidase (MnP) by Phanerochoete chrysosporium in a new solid-state bioreactor, the immersion bioreactor, operating with lignocellulosic waste, such as wood shavings, was investigated. Maximum MnP and lignin peroxidase (LiP) activity of 13.4 and 8.48 mukat/l, were obtained, respectively. The in vitro decolorization of several synthetic dyes by the extracellular liquid produced in the above-mentioned bioreactor (containing mainly MnP) was carried out and its degrading ability was assessed. The highest decolorization was reached with Indigo Carmine (98%) followed by Bromophenol Blue (56%) and Methyl Orange (36%), whereas Gentian Violet was hardly decolorized (6%).
