- Abstract
By high-throughput sequencing and metabolomics, the physicochemical metabolites and microbial community structure during cigar tobacco fermentation were analyzed, and then functional microorganisms and cooccurring taxa were identified by correlation analysis and network analysis to reveal the impact of microbiota on the quality of cigar tobacco. The results showed that the relative abundances of the dominant microbial genera Staphylococcus and Aspergillus increased first and then decreased during fermentation, and dominated the bacterial and fungal communities on the 21st day, respectively. Aspergillus, Staphylococcus, Filobasidium might have direct or indirect effects on the production of total and reducing sugars. Bacillus might have degradation effect on nitrogenous substances. In particular, Candida, as co-occurring taxa and biomarker in the later stage of fermentation, could not only degrade nitrogenous substances, synthesize flavor substances, but also play an important role in maintaining the stability of microbial community structure.
