The invention discloses a facultative anaerobic bacillus altitudinis strain and an application thereof in tobacco, the facultative anaerobic bacillus altitudinis strain ZY02-1 is classified and named as Bacillus altitudinis, the strain is preserved in the China General Microbiological Culture Collection Center (CGMCC), and the preservation number is CGMCC No.33916. The invention further discloses a preparation method of the facultative anaerobic bacillus altitudinis strain. The strain is a facultative anaerobic bacterium, can be fermented under two conditions of an aerobic environment and an anaerobic environment, can promote combined nicotine to be converted into free nicotine in a low-oxygen environment, increases the nicotine content of tobacco stems, effectively accelerates decomposition of aroma precursors such as polyphenols and terpenes in the tobacco stems, effectively increases aroma substances of the tobacco stems, and has the advantages of high yield, high yield and the like before re-drying. The bacillus altitudinis ZY02-1 is applied to moisture regaining tobacco stems for stacking fermentation, offensive odor of the fermented tobacco stems is reduced, aroma quality, aroma quantity and concentration are improved, nicotine, megastigmatrienone, geraniol and alpha-pinene are remarkably increased, and aroma components such as alpha-cedrene and ocimene are added.

The application relates to the technical field of analytical detection, in particular to an electrochemical gas sensor for detecting limonene and a preparation method thereof. The preparation method is as follows: multi-walled carbon nanotubes are dispersed in a ZnO nanoparticle solution, and then a composite material modified electrode is prepared by coating the multi-walled carbon nanotubes on the surface of the electrode; then, limonene template molecules and acrylamide functional monomers are dispersed in an alcohol solvent, and a polymer solution is prepared by polymerization under the action of a crosslinking agent and an initiator; finally, the polymer solution is coated on the surface of the composite material modified electrode, and the electrochemical gas sensor is prepared after eluting the template molecules. The sensor can sensitively and accurately detect the content of limonene gas released by plants, realizes stable and accurate detection of limonene in a complex environment with high specificity and high sensitivity, and provides important theoretical basis and technical support for cultivating high-quality crops and helps the innovative development of the field of crop breeding.

The invention relates to a process for preparing a polyisoolefin homo- or copolymer, preferably selected from butyl rubber, polyisobutylene and poly(isobutylene-co-para methyl styrene), the process comprising the step of polymerizing at least one isoolefin monomer and optionally at least one copolymerizable monomer, preferably multiolefin monomer, in the presence of a preformed polymeric stabilizer. The preformed polymeric stabilizer comprises repeating units derived from styrene and repeating units having pendant linear or branched saturated alkyl groups with at least 3 carbon atoms. Preferably, the repeating units with the pendant alkyl groups are derived from monoterpenes, especially myrcene or ocimene, or sesquiterpenes, especially farnesene, and subsequently hydrogenated. The preformed polymeric stabilizer advantageously stabilizes the slurry of the polyisoolefin homo- or copolymer, preferably selected from butyl rubber, polyisobutylene and poly(isobutylene-co-para methyl styrene), that is formed during polymerization in a solvent.

The invention relates to a tobacco flavor presenting fresh and sweet fruity flavor, flavor adsorption particles and application of the tobacco flavor and the flavor adsorption particles in cigarettes. The tobacco flavor comprises fingered citron peel essential oil, ocimene, linalool, beta-phellandrene, limonene, cyclohexene and beta-caryophyllene. Six specific spice components are creatively combined to form the mixed spice, compared with single fingered citron peel essential oil serving as a spice, the components in the spice are mutually matched and have a synergistic effect, fresh and sweet fruity flavor can be provided when cigarettes are smoked, the fruity, sweet and faint scent characteristics of the cigarettes are obviously improved, the aroma harmony is good, and the flavor of the cigarettes is greatly improved. The smoke characteristic of the cigarette can be improved; and after the perfume is used for slow release treatment, the stability of the fresh and sweet fruity flavor can be maintained, and the flavor of the perfume cannot be changed due to the change of the original proportion of the components in the slow release process, so that the stability of sensory expression is realized, and the sensory quality of tobacco products is comprehensively improved.

The invention relates to the technical field of microorganisms, in particular to a method for improving quality and insect resistance of purple perilla through inoculation of arbuscular mycorrhizal fungi, which is characterized in that the arbuscular mycorrhizal fungi are rhizosporium endophyllum, and insects are beet armyworms. The arbuscular mycorrhizal fungi are inoculated, so that the growth of the aboveground part and the underground part of the purple perilla is remarkably promoted, and the biomass of the purple perilla is improved; accumulation of linalool, perillyl alcohol, perillaldehyde, elemene, ocimene and limonene in the perilla leaves can be promoted, and the quality of the perilla is improved; the content of defense secondary metabolites such as flavone and tannin of the perilla leaf and the activity of defense enzymes such as polyphenol oxidase and phenylalanine ammonialyase can be improved, and the resistance of the perilla leaf to beet armyworms is improved. After the arbuscular mycorrhizal fungi inoculated perilla leaves are eaten, the growth and development of the beet armyworms are inhibited, and the beet armyworms show that the weight and the body length are reduced, and the developmental duration is prolonged.

This invention discloses a method for preparing trans-1,2-polyocimene and its application. The method includes dissolving a rare earth compound, an organoboron compound, and an alkylaluminum compound in an organic solvent in a certain proportion under inert gas protection to obtain a catalyst composition solution; directly adding (E)-β-ocimene to the catalyst composition solution; or dissolving (E)-β-ocimene in an organic solvent to prepare an ocimene solution, and adding the catalyst composition solution to the ocimene solution; mixing the (E)-β-ocimene or the ocimene solution with the catalyst composition solution and reacting at a preset temperature for a period of time, then adding a terminator to terminate the polymerization reaction; after sedimentation and drying, trans-1,2-polyocimene is obtained. The catalyst composition used in this method can catalyze the polymerization of (E)-β-ocimene with high activity and high selectivity to obtain trans-1,2-polyocimene.
