“…During cigar tobacco air-curing in humid environments, the natural fungal spores in the air and curing facilities attach to the leaf surfaces. At optimal temperatures and humidity, the fungi utilize the nutrients in the tobacco leaves to invade the tissue and proliferate extensively ( Drachev et al, 2004 ; Fleurat-Lessard, 2017 ; Liu et al, 2021 ; Zhao et al, 2022 ). The growth of mold pathogens during cigar tobacco air-curing relies on specific nutrients ( Schmidt et al, 2019 ).…”

IntroductionThe air-curing process of cigar tobacco, as a key step in enhancing the quality of cigars, is often susceptible to contamination by mold spores, which severely constrains the quality of cigar tobacco.MethodsThis study employed high-throughput Illumina sequencing technology and a continuous flow analysis system to analyze the differences between the microbial communities and physicochemical components of moldy and healthy cigar tobacco leaves. Furthermore, correlation analysis was performed to reveal the impact of mold on the quality of cigar tobacco.ResultsThe differences between the microbial flora and physicochemical compositions of moldy (MC) and healthy (HC) tobacco leaves were analyzed, revealing significant disparities between the two groups. Aspergillus spp. represented the dominant mold in MC, with nine out of twelve isolated molds showing higher quantities on MC than on HC. Mold contamination notably decreased the total nitrogen (TN), total phosphorus (TP), total alkaloids (TA), starch, protein, and flavor constituents while increasing the total fatty acid esters (TFAA), which was accompanied by a shift towards weakly acidic pH in the leaves. Fungal community analysis indicated a significant reduction in the fungal operational taxonomic unit (OUT) numbers and diversity indices in MC, contrasting with the bacterial trends. Aspergillus exhibited significantly higher relative abundance in MC, with LEfSe analysis pinpointing it as the primary driver of differentiation. Furthermore, significant negative correlations were observed between Aspergillus and TP, starch, TA, and protein, while a significant positive association was evident with TFAA. Network analysis underscored the pivotal role of Aspergillus as the species influencing disparities between HC and MC, with its abundance serving as a critical determinant during the air-curing process.DiscussionThis study elucidated substantial quality distinctions between MC and HC during air-curing, with Aspergillus emerging as the key species contributing to leaf mold.

The forthcoming integration of Bulgaria to the European Union has laid to the tobacco producers the need of increasing the tobacco quality of Virginia variety group. Implementation of introduced varieties aims at increasing the quality and maintaining the manufacture in compliance with demands of raw stuff of defined quality features. The purpose of the study was to perform technological studies on the major quality indicators of Virginia introduced varieties compared to the tobaccos of the same variety group mass grown in the areas of South Bulgaria. The analysis and valuation in comparing of the check varieties with the introduced ones was performed on the basis of the objective and subjective indicators, describing the quality, applied in our country. The final valuation with view of demonstration of a possible higher quality or vice versa, was based on a complex valuation. The summary of the results demonstrates that it is reasonable to extend the area of application of the introduced varieties К394 and PVH19, whereas it cannot be expected any deterioration of the variety composition, but rather the reverse-the same is more likeable to become better.
