The impact of <i>Staphylococcus saprophyticus</i> on the fermentation of cigar filler tobacco leaves and the dynamics of microbial community.

ABSTRACT:

Introduction

Staphylococcus has garnered increasing attention for its role in improving fermentation results and promoting the biosynthesis of aromatic compounds.

Methods

This study investigated the effects of exogenously introduced Staphylococcus saprophyticus on the microbial community structure, functional gene expression, and volatile aroma profiles during the fermentation of cigar filler leaves.

Results

The results demonstrated that S. saprophyticus significantly enhanced the accumulation of alcohols and ketones. LEfSe analysis identified Bacillus as a key differential genus in the inoculated group. Spearman correlation analysis revealed positive associations between Staphylococcus and Bacillus, as well as with key aroma
