Research progress on the application of microorganisms in the production process of domestic cigar tobacco leaves
This paper summarizes the research status and main problems in the types of cigar microorganisms and their application in field production,air-drying,fermentation and other links of domestic cigar tobacco leaves.It is believed that the microbial community of cigars could be divided into rhizosphere microorganisms,foliar microor-ganisms,and endophytic bacteria.The rhizosphere and leaf microorganisms of cigars could promote the growth and development of cigar plants,reduce plant diseases,and improve the sensory quality of tobacco leaves.However,there was a lack of research on beneficial endophytic bacteria.Microbial fertilizers and pesticides played an impor-tant role in the field growth of cigar tobacco leaves,but microbial fertilizers and pesticides for cigar tobacco plants had not been widely promoted and applied.During the process of cigar tobacco air-drying,there were abundant microbial resources and complex metabolic functions,but there was relatively little research on the mechanism of microbial action.During the fermentation process of cigar tobacco leaves,the microbial community structure gradu-ally diversified.The addition of medium microorganisms could improve the quality of tobacco leaves and prevent the occurrence of mold.However,most studies focus on the screening of medium microorganisms,and there was still a lack of in-depth research on the mechanism of microbial improvement and aroma enhancement.In the future,in-depth research could be carried out on the screening and utilization of endophytes in cigar tobacco leaves,micro-bial changes in the air-drying process,and in-depth data mining by using omics technology,in order to further improve the beneficial role of microorganisms in the production process of domestic cigar tobacco raw materials,improve the production and the quality of tobacco leaves,and further reduce the dependence on imported cigar tobacco raw materials.
