| 摘 要： | 用紫外分光光度法对4种外生菌根真菌降解矿物油的能力进行了研究.结果表明,这4种外生菌根真菌都具有降解矿物油的能力.但在不同的培养基中其生物量和降解矿物油的能力显著不同,以有机氮作为氮源及提供少量葡萄糖作为启动碳源将大大提高其生物量及矿物油降解率.结果为应用菌根技术修复矿物油污染土壤及优化降解条件提供了依据.

| Abstract: | The ability of 4 species of ectomycorrhizal fungi to degrade mineral oil was studied with ultraviolet spectrometry. The results showed that all of them were able to degrade mineral oil. Their biomass and ability of oil degradation vary with the kind of culture mediums evidently. Their biomass and oil degradation rate would increase greatly with organic nitrogen source and a little glucose as starting carbon source in the culture medium. The results provided basis for applying mycorrhizal technology to bioremediate mineral oil contaminated soil and optimising the degradation conditions. |
