摘要:
A process of producing a smoking article, preferably a cigar is described. After harvest, whole tobacco leaves are cured. Post-curing the leaves are threshed such that the leaf components are separated and the lamina is turned into strips. Tobacco strips are dipped and fermented for a period of time before being dried. The dried tobacco provides a filler for the cigar, which filler is wrapped in tobacco leaf to produce the smoking article , which is matured for a period.
摘要:
The invention provides laccases, polynucleotides encoding these enzymes, the use of such polynucleotides and polypeptides. In one aspect, the invention relates to the enzymatic production of nootkatone by way of the conversion of valencene using proteins having a laccase activity, e.g., a novel laccase of the invention. In one aspect, the invention provides methods of depolymerizing lignin, e.g., in a pulp or paper manufacturing process, using a polypeptide of the invention. In another aspect, the invention provides methods for oxidizing products that can be mediators of laccase-catalyzed oxidation reactions, e.g., 2,2-azinobis-(3-ethylbenzthiazoline-6-sulfonate) (ABTS), 1- hydroxybenzotriazole (HBT), 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO), dimethoxyphenol, and the like.
摘要:
The present invention generally relates to the reduction of the harmful effects of orally or transdermally delivered nicotine in conventional tobacco-use cessation programs. More specifically, embodiments concern methods of reducing the harmful effects of nicotine intake, associated with conventional tobacco-use cessation programs, by providing tobacco products, which contain a reduced amount of nicotine and tobacco specific nitrosamines (TSNAs).

Eine Zubereitung bestehend aus einem Pilz-lysierenden Enzymprodukt eines Streptomyceten und β-1,3-Glucanase eignet sich hervorragend zur Konservierung von mikrobiell verderblichen Produkten.
摘要:
L'invention concerne un perfectionnement au procédé papetier de reconstitution du tabac dans lequel la liqueur forte est aromatisée par fermentation avec une levure, avant d'être utilisée pour réimprégner la feuille de base, ainsi que les tabacs reconstitués aromatisés obtenus par ce procédé. Après un séjour des débris de tabac en solution aqueuse dans un digesteur (10,11), on sépare par passage dans une presse (12) la liqueur forte des fibres que l'on traite séparément pour former une feuille de base.
摘要:
An improved process for the reduction of the nitrate content of tobacco materials via dissimilatory denitrification is disclosed wherein more rapid reduction of nitrate to nitrogen gas is effected by utilizing a vacuum during incubation. The process comprises inoculating nitrate-containing tobacco material with a microorganism capable of dissimilatory denitrification and thereafter incubating the tobacco material under conditions whereby the nitrate is reduced to nitrogen gas via dissimilatory denitrification while applying a vacuum.
