Method for improving tobacco leaf quality through bacillus mojavensis fermentation

The invention relates to the technical field of tobacco processing, and discloses a method for improving tobacco leaf quality through bacillus mojavensis fermentation. According to the invention, a dominant strain Bacillus mojavensis is screened, analyzed and identified from cigar tobacco leaves, the dominant strain Bacillus mojavensis is cultured and then inoculated to the cigar tobacco leaves for fermentation, the content of plant alkaloid and nitrogen-containing compounds is effectively reduced, the total sugar content in the tobacco leaves and the content of neutral aroma components such as solanone, neophytadiene, phytol and the like are increased, and the yield of the cigar tobacco leaves is increased. Offensive odor is effectively relieved, fragrance is added, and the sensory quality of tobacco leaves is improved. 本发明涉及烟草加工技术领域，公开了一种莫海威芽孢杆菌发酵提高烟叶品质的方法。本发明通过在雪茄烟叶中筛选并分析鉴定出一株优势菌株莫海威芽孢杆菌，将之进行培养后再接种到雪茄烟烟叶上进行发酵，有效降低植物碱及含氮化合物含量，提高烟叶中总糖含量及茄酮、新植二烯、植物醇等中性致香成分的含量，有效减轻杂气，增添香气，提升烟叶感官品质。
