Application of starch-degradation bacteria in cigar tobacco leaf fermentation: effects on starch degradation, microbial communities and metabolic pathways.

ABSTRACT:

Objective

This study aims to explore the effects of inoculating starch-degrading strains on the starch content and microbial metabolic pathways of cigar tobacco leaves.

Method

By isolating and screening starch-degradation bacteria from the surface of Dominican tobacco leaves at the end of fermentation and applying them to the fermentation process of "Yunxue NO. 39" cigar tobacco leaves. The study systematically analyzed the starch content, microbial diversity and community structure, starch metabolic enzyme profiles and key metabolic pathway changes in tobacco leaves fermented for 18 and 35 days, integrating physicochemical composition, non-targeted metabolomics and metagenomics.

Result

The results indicated that both strains Bacillus pumilus and Baci
