HEEP COPYRIGHT: BIOL ABS. Cigar leaf tobacco (Nicotiana tabacum L.) was fermented in the laboratory with an application of Saccharomyces cerevisiae or Candida pseudopicalis or without either at 30 degrees C or 40 degrees C. The following results were obtained: The tobacco samples were well fermented at 30 degrees C by the multiplication of bacteria. The addition of Saccharomyces or Candida resulted in a rise in the number of bacteria during the early stage of fermentation. Total particulate matter and benzo(a)pyrene content in the smoke of the fermented tobacco were not decreased positively by the fermentation treatment.
