In different degrading phases, the degrading products of carbofuran by CDS-1(Sphingomonas sp. ) were extracted by acetone. According to the analysis of gas chromatography/mass spectrometry (GC/MS), carbofuran-7-phenol was identified as the initial degrading product, and an unknown metabolite with molecular weight of 182 was determined as 2-hydroxyl-3-tertiarybutylalcohol-phenol, which was the next degrading product of carbofuran-7-phenol. According to the analysis of GC/MS and gas chromatography/Fourier transform infrared spectrum (GC/FTIR), the main component of the compounds that appeared in the final phase of degradation which could produce volatile pungent odor, was identified as carvone.
