Fungi of the Ascomycota phylum were isolated from oil-soaked sand patties collected from beaches following the Deepwater Horizon oil spill. To examine their ability to degrade oil, fungal isolates were grown on oiled quartz at 20°C, 30°C and 40°C. Consistent trends in oil degradation were not related to fungal species or temperature and all isolates degraded variable quantities of oil (32-65%). Fungal isolates preferentially degraded short (<C18; 90-99%) as opposed to long (C19-C36; 7-87%) chain n-alkanes and straight chain C17- and C18-n-alkanes (91-99%) compared to their branched counterparts, pristane and phytane (70-98%). Polycyclic aromatic hydrocarbon (PAH) compounds were also degraded by the fungal isolates (42-84% total degraded), with a preference for low molecular weight over high molecular weight PAHs. Overall, these findings contribute to our understanding of the capacity of fungi to degrade oil in the coastal marine environment.
从深海地平线溢油事件后的海滩上采集的含油沙饼中分离出了子囊菌门真菌。为了研究它们降解石油的能力，将真菌分离物在 20°C、30°C 和 40°C 下在含油石英上培养。石油降解的一致趋势与真菌种类或温度无关，所有分离物都降解了不同数量的石油（32-65%）。真菌分离物优先降解短链（<C18；90-99%）而非长链（C19-C36；7-87%）正构烷烃和直链 C17 和 C18-正构烷烃（91-99%），而不是它们的支链类似物姥鲛烷和植烷（70-98%）。真菌分离物还降解了多环芳烃（PAH）化合物（总降解率为 42-84%），对低分子量 PAH 的偏好高于高分子量 PAH。总的来说，这些发现有助于我们了解真菌在沿海海洋环境中降解石油的能力。
