Effect of Flue-curing Condition on the Change of Bacteria during Curing of Flue-cured Tobacco

The changes in types and amounts of bacteria in different curing methods and conditions were observed.The results showed that the types of bacteria decreased with the curing process going on, and appeared to be no significant effect with the different curing conditions.The populations of bacteria gradually increased at the yellowing stage, and decreased after yellowing.The amount of bacteria was greater in bulk curing and in curing with high temperature and humidity was greater than that in conventional flue curing or curing with and low temperature and humidity.It was suggested that the lower temperature and humidity at the yellowing stage could inhibit bacteria activity.
