  • Publication number: 20190276834
    Abstract: Methods and compositions are provided for expressing an endolysin in a bacterium or in a tobacco plant or plant part. Expression of the endolysin can reduce the total bacterial load on the plant and in tobacco products produced from the plant. Accordingly, the level of tobacco specific nitrosamines (TSNA) in a cured tobacco product can be decreased when the tobacco leaves used in the product were harvested from a plant expressing endolysin or when bacteria modified to express endolysin is used to treat the tobacco. Thus, bacteria and tobacco plants and plant parts are provided that express an endolysin. Further provided are methods for decreasing the microbial load on a tobacco plant and in a tobacco product by applying a solution of bacteria modified to express an endolysin or by modifying a tobacco plant to express endolysins. Smokeless tobacco products including such modified tobacco plant parts are also provided.

  • Patent number: 10258079
    Abstract: A smoking article, such as a cigarette, includes a carbonaceous heat source. A mouth end piece segment is located at the mouth end of the smoking article, and the mouth end piece segment allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generating segment located between the heat generation segment and the mouth end piece segment. The aerosol-generating segment incorporates an aerosol-forming material (e.g., glycerin and flavors). The heat generation segment is in a heat exchange relationship with the aerosol-generating region such that heat generated by the burning fuel element acts to volatilize aerosol-forming material for aerosol formation. The carbonaceous heat source is in intimate contact with coarse, fine or ultrafine particles of materials such as cerium oxide, or mixtures of cerium oxide and palladium chloride.
