Isolation and Identification of the Microflora on Tobacco Leaves during the Natural Fermentation of Flue-cured Tobacco

Microflora of flue-cured tobacco Hongda, NC89 and K326 varieties during the natural fermentation were studied. The results showed that dominant microorganisms isolated were bacteria, while actinomycetes and mould were little. The dominant microorganisms of bacteria were identified as Bacillus. The dominant microorganisms of mould were identified as Aspergillus.The microorganism amount and species on the leaves of the natural fermentation of flue-cured tobacco were related to the species, producing area, grade, and aging time of tobacco. More amount and species of microorganism were isolated from fine varieties of flue-cured tobacco.
