Nicotine degradation by micro-organisms has received increasing attention in the past 50 years because microorganisms have the potential to reduce nicotine levels in tobacco. As an environment-friendly treatment, microbial degradation of nicotine has been considered as a promising method due to its low cost and high efficiency. However, the current understanding of nicotine metabolism in micro-organisms is poor. Therefore aim of the present investigation was to isolate nicotine degrading bacteria from oral cavity in tobacco chewers and to study its effect on nicotine degradation. Oral swab samples were collected from tobacco consumers. In the present study the bacteria identified was found to be Lactobacillus sp. The inhibitory concentration of nicotine for the nicotine degrading bacteria was studied. It was observed that the increased concentration of nicotine in the nicotine liquid medium was inhibitory to the growth of bacteria in the medium. It was concluded that Lactobacillus sp. present in mouth can utilize and breakdown the nicotine. But it should also be taken into consideration that increased amount of nicotine has been found to be inhibitory for these nicotine utilizing bacteria as well.
