Solid-state production of lignin peroxidase (LiP) and manganese peroxidase (MnP) by Phanerochaete chrysosporium using steam-exploded straw as substrate.
In the used media mainly consisting of steam-exploded wheat straw, the straw, which could replace expensive veratryl alcohol, might act not only as nutrient, but also as inducer of lignin enzymes. The activities of the enzymes lignin peroxidase (LiP) and manganese peroxidase (MnP) in solid-state fermentation (SSF) were far higher than in submerged fermentation (SmF). Under optimal conditions of SSF, the maximum activities of the enzymes Lip and MnP were 2600 and 1375 U/L, respectively. Thus, this would pave the way for production and application of lignin enzymes on a large scale.
