Omics Analysis of Lignin Degradation by the Gut Microbiomes of Wood-Eating Hypomeces squamosus Fabricius.

ABSTRACT: Microbial degradation of lignin is important to carbon cycling. The gut microbiome of wood-feeding Hypomeces squamosus Fabricius has been shown to degrade lignin efficiently. However, the specific degradation mechanisms remain incompletely understood. In this study, we investigated the mechanism of lignin degradation using omics comparative analysis, focusing on differentially expressed genes and metabolic pathways in the gut microbiome of insects fed with a lignin-rich diet. The dominant genus taxon was Pantoea (29.82%), which was predominant in insects fed with high lignin-containing Iris ensata Thunberg, whereas Wolbachia and Enterobacter were predominant in insects fed with cabbage leaves (MHS_K group). Furthermore, expression levels of carbohydrate-active enzymes from the auxiliary ac
