  • MICROBIAL FERMENTATION METHOD FOR IMPROVING TOBACCO QUALITY
    Publication number: 20230389594
    Abstract: A microbial fermentation method for improving tobacco quality, comprising the following steps: (1) inoculating flue-cured tobacco as an inoculation source into a tobacco powder medium, and cultivating at 20-40° C. for 20-50 h; (2) inoculating microbial liquid in step (1) into a fresh tobacco powder medium, cultivating at 20-40° C. for 20-50 h, and circulating for 15-25 cycles to obtain stable flue-cured tobacco microbial flora; (3) inoculating the microbial flora obtained in step (2) into the fresh tobacco powder medium, and culturing at 20-40° C. for 20-50 h to obtain seed liquid of the microbial flora; (4) centrifuging the microbial liquid obtained in step (3) and collecting microbes; (5) washing the microbes collected in step (4); (6) resuspending the washed bacteria in step (5) to obtain a microbial suspension; and (7) spraying the microbial suspension in step (6) to the tobacco leaves for fermentation for 6-8 days.
