Abstract
A new isolate, identified as Gordonia sp. ZD-7 by 16S rDNA sequence analysis, grew in n-hexadecane containing dibenzothiophene (DBT) which was degraded from 2.8 mM to 0.2 mM within 48 h. Biodesulfurization could be repeatedly performed for more than 190 h, with average desulfurization rates of 5 mmol DBT kg cells (dry wt)(-1) h(-1).
摘要
通过16S rDNA序列分析鉴定为戈登氏菌属ZD-7的一种新分离菌株，能在含有二苯并噻吩（DBT）的正十六烷中生长，48小时内DBT浓度从2.8 mM降至0.2 mM。生物脱硫可重复进行超过190小时，平均脱硫速率为5 mmol DBT·kg细胞（干重）⁻¹·h⁻¹。
