微生物降解烟碱研究应用进展

对微生物降解烟碱的研究进展进行了回顾,并针对不同微生物降解烟碱的产物和所获得的结果进行了分析比较。介绍了降解烟碱的3种途径:吡咯烷途径、吡啶途径和脱甲基途径,着重分析了当前研究较多的两种微生物———噬烟碱节杆菌和球形节杆菌的烟碱代谢途径。目前国产烟叶普遍存在烟碱含量偏高的问题,尤其是上部烟叶烟碱含量过高而难以较多用于叶组配方中,因此在工业上研究利用微生物对烟草进行降解烟碱处理具有实际应用价值。

Advances in Microbial Degradation of Nicotine and its Application

The studies on degradation of nicotine by microbes were reviewed and the degradation products by different microbes were compared. The three major degradation pathways of nicotine, including pyrrolidine pathway, pyridine pathway and Me pathway, were introduced, the degradation pathways of Arthrobacter nicotinovorans and Arthrobacter globiformils were emphatically analysed. It was suggested that the usability of some Chinese tobacco leaves with high nicotine content, especially the upper leaves, would probably be improved by adequately treated with these microbes.
