Effects of Bacillus biologics on chemical composition of redryed tobacco

  • Received Date: 2019-01-04
  • Three strains screened from the surface of tobacco leaves could be used for inproving tobacco aroma:Bacillus altitudinis (Y2), Bacillus licheniformis (D3), and Bacillus subtilis (L1). They were prepared to single and compound biologics for solid-state fermentation of tobacco, then the routine chemical components, aroma substances of tobacco and petroleum ether extract were detected. The results showed that:the total sugar and reducing sugar content of tobacco leaves decreased after solid-state fermentation of tobacco was inoculated with single strains. The content of aroma substance such as carbonyls, acids and esters in tobacco leaves increased, and the aroma components were also richer. After solid-state fermentation with compound biological agents, the total sugar and reducing sugar content of tobacco leaves decreased, and the treatment consisting of Y2+L1 compound treatment could effectively reduce the content of nicotine and increase the ratio of sugar to alkali.It did not show superposition effect on the aroma components and, on the contrary,it exhibited a completely opposite trend on some aroma substances. D3 treatment or Y2+D3 compound treatment could increase the content of petroleum ether extract and showed strong aroma producing effect.
