Application of yeast in plant-derived aroma formation from cigar filler leaves
TL;DR: In this article , the results showed that 120 volatile components were identified and quantified in cigar filler leaves after fermentation, including aldehydes (25 types), alcohols (24 types), ketones (20 types), esters (11 types), hydrocarbons (12 types), acids (4 types) and other substances (23 types).
Screening of cellulase-producing bacteria and their effect on the chemical composition and aroma quality improvement of cigar wrapper leaves
TL;DR: In this paper , a high yield cellulase production strain was screened from the surface of cigar wrapper leaves and added to the leaves for fermentation, and the results showed that under the conditions of inoculation concentration of 20%, fermentation temperature of 37 °C, addition of 4.5 ‰ glucose and 2.25 ‰ glutamate, the highest degradation rate of tobacco cellulose was 31.7%.

Effect of hydrogen sulfide (H2S) on the growth and development of tobacco seedlings in absence of stress
Jingcheng Dai,Dingxin Wen,Hao Li,Jingpeng Yang,Xiong Rao,Yong Yang,Jiangke Yang,Chunlei Yang,Jun Yu +8 more
TL;DR: Exogenous hydrogen sulfide (H2S) promotes endogenous H2S production, enhancing agronomic traits, photosynthetic pigments, and root vigor in tobacco seedlings, while also increasing antioxidant enzyme activities and reducing oxidative stress, suggesting a novel signaling molecule for plant growth and development.

Effect and mechanism of NaHS on tobacco bacterial wilt caused by Ralstonia solanacearum
Dingxin Wen,Qingqing Guo,Wan Zhao,Yong Yang,Chunlei Yang,Jun Yu,Yunhan Hu +6 more
TL;DR: In this paper , the authors evaluated the impacts of the H2S donor sodium hydrosulfide (NaHS) on the antibacterial activity, morphology, biofilm, and transcriptome of R. solanacearum to understand the effect and mechanism of NaHS on tobacco bacterial wilt.
Heterogeneity changes of active bacterial community on cigar filler leaves after fermentation based on metagenome.
TL;DR: In this article , the changes of surface bacterial diversity of cigar filler leaves were investigated by high-throughput sequencing technology, and it was found that the surface bacterial richness was declined after fermentation, and the dominant microorganisms evolved from Pseudomonas spp. before fermentation to Staphylococcus spp after fermentation.
