Enhanced lignin peroxidase synthesis by Phanerochaete Chrysosporium in solid state bioprocessing of a lignocellulosic substrate

A solid state fermentation (SSF) process for the production of lignin peroxidase was optimized to enhance enzyme production by Phanerochaete chrysosporium. Optimization of the corncob SSF medium caused a significant reduction in fermentation time to give maximum lignin peroxidase yield. Supplementat...

Zusammenfassung:	A solid state fermentation (SSF) process for the production of lignin peroxidase was optimized to enhance enzyme production by Phanerochaete chrysosporium. Optimization of the corncob SSF medium caused a significant reduction in fermentation time to give maximum lignin peroxidase yield. Supplementation of the SSF medium by low concentrations of peptone, yeast extract and Tween-80 enhanced lignin peroxidase production. Maximum yield of lignin peroxidase was 13.7 U/gds (units per gram dry substrate) noted after 5 days of SSF with 70% moisture and 20% (v/w) inoculum.[PUBLICATION ABSTRACT]
