    Yunnan Tobacco Science Research Institute, Yuxi, Yunnan, China.
    A bacterial strain L1, capable of degrading 1.5 g/l nicotine, was isolated from tobacco leaves. It was identified as a member of Bacillus simplex based on morphology, physiological and chemical tests, 16S rDNA sequence and phylogenetic characteristics. ...
