    Effects of flue-curing on cigarette smoke condensates mutagenicity

    MORIN A.; POIRIER N.; PREFONTAINE D.; & al.
    Imperial Tobacco Canada Ltd, Montreal, Quebec, Canada
    Flue-curing is a post harvest conditioning process which strongly affects the tobacco leaf chemistry, and consequently the chemical properties of tobacco smoke. Several studies identified the major changes in tobacco chemistry occurring during flue-curing ...

    Monitoring the bacterial and fungal biota of eleven tobacco grades stored at three different locations

    VILLEMUR R.; LACASSE M.; MORIN A.
    2900 Beaudoin, Montreal, QC, H4K 2R5, Canada
    Tobacco as many other plants has its own microbiota. There are very few studies determining the evolution of this microbiota during tobacco storage, which may affect the quality of tobacco. Polymerase chain reaction (PCR) combined with denaturing gradient ...

    Use of a tobacco agar medium (TAM) to detect Cryptococcus and Candida colonies isolated from tobacco

    MORIN A.; JOLY J.
    Imperial Tobacco Canada Ltd, Montreal, Quebec, Canada
    The use of a tobacco agar medium (TAM) was investigated to visually differentiate Cryptococcus species from Rhodotorula and Candida species that can be isolated from tobacco. This study was first conducted with pure isolates of each of the major yeast ...

    Predictivity and variability of in vitro bioassays routinely used to estimate the toxicity of cigarette smoke

    PROUDLOCK R.; LAPIERRE J.; MORIN A.
    Charles River Laboratories, Montreal, Imperial Tobacco Canada Limited, Montreal, Canada.
    An amendment to the Tobacco Act is currently being introduced in Canada. This will require all brands of cigarettes sold in this country to be subjected to a set of three in vitro assays on an annual basis. The purpose of the amendment is to monitor ...
