This document summarizes research on analyzing the microbial community in the hindgut of a termite species through metagenomic sequencing. Key findings include: 1) Over 700 glycoside hydrolase catalytic domains were identified from the termite hindgut metagenome, including novel cellulases and hemicellulases. 2) The termite hindgut microbiota is dominated by spirochetes (Treponema) and Fibrobacteres, which were found to encode many wood-degrading enzymes. 3) Proteomics analysis showed that glycoside hydrolases are expressed and secreted by the symbiotic microbes, and recombinantly expressed cellulases showed
