A process for the reduction of the nitrate and nicotine contents of tobacco by microbial treatment is disclosed wherein tobacco materials are subjected, under controlled conditions, to the action of a microorganism effective to degrade nitrates and alkaloids (nicotine) through a biochemical reaction. The microorganism is combined or grown in the presence of a nitrate containing compound in relatively small quantities. Tobacco treated in accordance with this process has a reduced nitrate and nicotine content, and when incorporated into a tobacco smoking product thereby produces a mild smoke, having reduced nitrogen oxides, hydrogen cyanide and nicotine content. However, there is no loss of desirable flavor, taste and smoking properties.

A tobacco product having a reduced nicotine content. Tobacco is subjected, under controlled conditions, to the action of a microorganism effective to degrade nicotine through a biochemical reaction in which, inter alia, 3-succinoylpyridine is formed. Tobacco treated in accordance with this process, when incorporated into a tobacco smoking product, produces a mild smoke, having a reduced nicotine content. However, there is no loss of desirable flavor, taste and smoking properties.
