Abstract

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.

摘要

在不同的降解阶段，通过丙酮提取CDS-1（鞘氨醇单胞菌属）对呋喃丹的降解产物。根据气相色谱/质谱（GC/MS）分析，呋喃丹-7-酚被鉴定为初始降解产物，一种分子量为182的未知代谢物被确定为2-羟基-3-叔丁醇-苯酚，它是呋喃丹-7-酚的下一个降解产物。根据GC/MS和气相色谱/傅里叶变换红外光谱（GC/FTIR）分析，在降解最后阶段出现的、可产生挥发性刺鼻气味的化合物的主要成分被鉴定为香芹酮。
