Research progress in nicotine degradation by Pseudomonas

Abstract:

Nicotine is the most abundant alkaloid in tobacco and causes serious harm to both the environment and the human body. Microorganisms using nicotine as the energy source for growth can serve environmental remediation. Pseudomonas strains grow quickly and are highly adaptable to the environment. Moreover, they can grow with nicotine as the only carbon and nitrogen source, with excellent degradation performance and research potential. To elucidate the characteristics and mechanism of nicotine degradation by Pseudomonas, this paper introduced the strains and characteristics of Pseudomonas that can degrade nicotine, detailed the intermediates and pathways of nicotine degradation by Pseudomonas, and summarized the related genes. Finally, this paper prospected the ways to improve the ability of Pseudomonas in degrading nicotine, aiming to provide guidance for future research and applications of microbial degradation of nicotine.
