- Bacterial-Fungal interactions play a crucial role in cigar tobacco fermentation, influencing flavor compound formation and reducing irritating compounds.
- Key microbial taxa identified include Aspergillus (fungi) and Pseudomonas (bacteria), which enhance fermentation quality.
- Microbial community diversity (α-diversity) increases initially but decreases after the mid-phase of fermentation.
- Bacterial community restructuring occurs earlier than fungal succession during fermentation.
- The fermentation process is divided into three phases: rapid change (T1-T3), slow change (T3-T5), and stable (T5-T7).
- Proteobacteria and Ascomycota show a strong positive correlation, with Pseudomonas and Aspergillus acting as functional hubs.
- Synergistic metabolism of key microbes may contribute to nicotine degradation and volatile compound formation.
- The study provides insights for targeted regulation of cigar flavor through microbial consortia.
