多环芳烃 (PAH) 的代表可被木质素分解真菌 Irpexlacteus 降解。通过GC-lon阱质谱分析产物。全扫描质谱、产物离子扫描 (MS-MS) 和蒽、菲、荧蒽和芘降解产物的衍生化相结合，进一步深入了解了 I.lacteus 引发的降解机制。特别是，产物离子扫描能够解释未知的降解产物，即使它们仅以痕量水平产生。大多数建议的结构后来都得到了真实标准的确认。 (C) 2002 Elsevier Science B.V. 保留所有权利。
Representatives of polycyclic aromatic hydrocarbons (PAHs) were degraded by ligninolytic fungus Irpex lacteus. The products were analyzed by GC-lon trap mass spectrometry. The combination of full scan mass spectra, product ion scans (MS-MS) and derivatization of the degradation products of anthracene, phenanthrene, fluoranthene and pyrene provided further insight in the degradation mechanism initiated by I. lacteus. Particularly, the product ion scans enabled the interpretation of unknown degradation products, even though they were only produced at trace level. Most of the structures suggested were later confirmed with authentic standards. (C) 2002 Elsevier Science B.V. All rights reserved.
