Microbial community succession during tobacco fermentation reveals a flavor-improving mechanism.

ABSTRACT:

Introduction

Flue-cured tobacco (FCT) requires fermentation to increase quality, with microorganisms playing a key role. However, microbial succession and functions during long-term fermentation remain unclear. Artificial microbial fermentation, which is more controllable and efficient, focuses on mining functional strains to optimize the process.

Methods

In this study, the microbial community structure and function of FCT fermentated for 0-4 years were analyzed, and the changes of metabolites in tobacco leaves in different years were analyzed. Functional microorganisms were screened, and their potential for application in FCT fermentation was evaluated.

Results

The results revealed that the FCT aging process was typified by the metabolic, transformative, and syntheti
