Multi-omics provides insights into dynamic changes of microbiota and metabolic profile during fermentation process in cigar tobacco (Nicotiana tabacum L.) leaves

Accurately determining the optimal fermentation time is crucial for producing high-quality raw materials for cigar tobacco products. It is essential to understand the changes in microorganisms and metabolites closely associated with the quality of cigar tobacco leaves (CTLs) during the fermentation process. Therefore, it is necessary to conduct tests and analyze the microorganisms and metabolites throughout the fermentation process of cigar tobacco leaves.
