Microbacterium testaceum facilitates polysaccharide decomposition during post-harvest aging of tobacco leaves by recruiting keystone bacterial taxa.

ABSTRACT: The use of functional microorganisms is a widely adopted, green, and efficient industrial technique for enhancing tobacco leaf quality. These microorganisms accelerate the degradation of macromolecular organic substances. However, their impact on the chemical composition of tobacco leaves across different aging durations and the mechanisms of polysaccharide degradation remain unclear. This study analyzed the degradation patterns of starch, pectin, cellulose, and hemicellulose at different time points (3 h, 2 months, 6 months, 36 months) during the tobacco aging process after the addition of Microbacterium testaceum, and compared the differences in microbial community structure, diversity, and molecular ecological networks. The results showed that compared with sterile water treatment of th
