摘要/Abstract

摘要： 探索用一株古地分支杆菌（Mycobacterium goodii）X7B菌株在固定化细胞体系中对汽油组分进行脱硫，通过生物脱硫实验，对于直馏汽油的脱除率达69.1％以上，进一步使用气相色谱-原子发射仪（GC-AED）对汽油脱硫前后的硫分布进行检测，发现X7B菌能有效地脱除汽油组分中的硫醇、硫醚等有机硫化合物，但对于噻吩类衍生物的处理能力有限，仅为36％。

Abstract: Biodesulfurization of gasoline by a mycobacterium goodii X7B in an immobilized-cell system was investigated and the result showed that over 69.1% of the sulfur content in the straight-run gasoline was removed. Gas Chromatography with Atomic Emission Detector (GC-AED) was used to detect the distribution of sulfur compounds in gasoline before and after desulfurization. Mycobacterium goodii X7B could remove organic sulfur compounds in gasoline, such as thiol and sulfide effectively while the ability of mycobacterium goodii X7B to remove thiophene derivatives was limited and only 36% of thiophene derivatives could be removed.
