中文摘要：

采用液体萃取法在不同的降解时期提取了细菌CDS-1（Sphingomonas sp．）降解呋喃丹的产物，经气谱-质谱联用（GC/MS）分析，分离鉴定出呋喃丹的首步代谢产物呋喃酚。通过化合物质谱行为分析，基本确定了分子量为182的未知化合物为2-羟基-3-叔丁醇基-苯酚，并且确定其为呋喃酚的下一步代谢产物。经气-质联用与气谱傅里叶红外光谱联用（GC/FTIR）分析，确定细菌在降解呋喃丹后期产生的具有刺激性气味的物质的主要成分为藏茴香酮。

英文摘要：

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-tertiary-butylalcohol-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.
