| 英文摘要 | Sewage sludge biodrying is a waste treatment method that uses bio-heat generated from organic degradation to remove moisture from sewage sludge. Lignocellulose and carbohydrate decomposition is important when assessing biodrying performance. This study investigated lignocellulose and carbohydrate decomposition, and the potential microbial functions during biodrying. We determined the lignocellulose and carbohydrate contents, assayed related enzyme activity, performed a complete metagenomic study on sewage sludge biodrying material during the thermophilic phase, annotated potential genetic function involved in the decomposition, and summarized the key metabolic pathways. The results indicated that lignocellulose, readily degradable carbohydrates, and starch, significantly decomposed after biodrying. During the thermophilic phase, the majority of lignocellulose and carbohydrate related enzymes showed significantly higher activity, and glycoside hydrolases and glycosyl transferases showed higher gene counts and reads. Moreover, the top five microorganisms enriched with carbohydrate-active enzyme genes, i.e., Bacillus, Intrasporangium, Tetrasphaera, Rhodobacter, and Streptomyces, were also among the top ten ecologically dominant genera. These findings highlight the crucial phases for biodrying process, reveal the ecologically functional diversity of biodrying-originated microbial consortia, and suggest potential candidates for optimizing biodrying decomposition.
