    Three fungal strains isolated from tobacco were cultured on tobacco water extracts. In these cultures, the mycelium weight was shown to be correlated with the concentration of a steroid, ergosta-5,7,22-trien-3beta-ol (ergosterol). This steroid is not a ...

    Philip Morris USA, Research Center, Richmond, VA, USA
    FT-IR evolved gas analysis, a non-isothermal pyrolysis technique, is used to probe the changes in tobacco leaf composition which occur during flue- and air-curing. A unique perspective of major enzymatic processes and their dependencies on curing method ...
