Gene expression of Ceriporiopsissubvermispora during lignocellulosic substrate degradation

Background Lignin is a complex aromatic polymer whose microbial degradation is essential for carbon recycling [1]. The fungus Ceriporiopsis subvermispora has attracted attention for its valuable biotechnological applications, especially for pretreatment of lignocellulosic material studies in order to expose the cellulose for hydrolysis and industrial fermentation. Thus, ligninolytic enzymes of white-rot fungi remain the subject of intensive investigations for their potential applications in a wide range of industrial bioprocesses and applications such as the paper industry, textile industry, decolorization of industrial wastewater treatment, and the degradation of organopollutants [2]. The goal of the present work was to grow C. subvermispora in coconut fibers as substrate in order to analyze its degradation potential and evaluate the lignin peroxidase expression (Lip1 and Lip2).
