Transcriptomics analysis reveals the high biodegradation efficiency of white-rot fungus Phanerochaete sordida YK-624 on native lignin

Lignocellulosic biomass is an organic matrix composed of cellulose, hemicellulose, and lignin. In nature, lignin degradation by basidiomycetes the key step in lignocellulose decay. The white-rot fungus Phanerochaete sordida YK-624 (YK-624) has been extensively studied due to its high ability. It was demonstrated that can secrete peroxidase manganese for degradation. However, underlying mechanism remains unknown. Here, we analyzed gene expression following growth under ligninolytic nonligninolytic conditions compared differentially expressed genes those model chrysosporium next-generation sequencing. More enzymes lignin-degrading auxiliary were upregulated YK-624. This might explain efficiency addition, involved energy metabolism pathways such as TCA cycle, lipid metabolism, carbon glycolysis first differential analysis reported this study. results obtained study indicated produces more metabolism.
