摘要： In our previous work, a microbial consortium GF-20 (Qinggeer et al., 2016) was enriched from compost habi-tats and adapted to efficiently and stably degrade corn stover under low temperatures. While the main microorganism and degradation-related functions and degradation-related coding enzyme genes of GF-20 were not clear. Therefore, the cur-rent study used the metagenomic to decipher the systematic and functional contexts within such microbial consortium un-der low temperatures. The results showed that the dominant functional microbials in GF-20 consortium were bacteria. The dominant phylums in GF-20 consortium were Proteobacteria (62.84%) and Bacteroidetes (10.24%). The dominant genus was Pseudomonas (50.84%), followed by Dysgonomonas (5.86%), Achromobacter (4.94%), Stenotrophomonas (3.67%) and Flavo-bacterium (2.04%). The metabolism was mainly composed of carbohydrate metabolism and amino acid metabolism, and in-cluded signal transduction, cell transport and other metabolic modes. The functional genes encoded were mainly distributed in glycosidolytic enzyme genes, and the functional enzymes were beta-glucosidase, acetyl-CoA, pyruvate dehydrogenase and galactosidase. The GF-20 microbial consortium degraded the cellulose in corn stover primarily by beta-glucosidase and endoglu-canase, which were produced by 12 genera of microorganisms. The hemicellulose synergistic effect was produced by 15 genera of microorganisms including xylanase, xyloglucanase, mannolanase and branching enzyme.
