- Abstract
Shandong tobacco leaves were fermented by Enterobacter cloacae F8-2 and Acinetobacter nosocomialis 7S-2 mixed bacteria. The sensory quality, chemical composition and chemical composition of tobacco smoke and microbial community on tobacco leaf surface before and after fermentation were studied. The results showed that when Enterobacter and Acinetobacter were mixed in 1:1 fermentation for 24 h, the aroma of the tobacco leaf increased and the impurity of the tobacco leaf decreased most significantly. After fermentation, methylheptenone, dihydrotomarone and 5-methylfurfural increased by 89.22%, 35.67% and 33.93%, respectively. Nerolol, solanone and acyl alcohol in tobacco smoke increased by 78.01%, 46.83% and 45.95%, respectively. Mixed fermentation had a great impact on the bacterial community on the surface of tobacco leaves, and the microorganisms cooperated with each other in fermentation and symbiosis. At the same time, Enterobacter and Acinetobacter may be related to the production of aromatic substances such as benzaldehyde and methyl heptene ketone.
