A new bacterial strain capable of selectively desulfurizing dibenzothiphene (DBT) was isolated from sludge. This organism, designated ZD-M2, clustered most closely with members of the genus Microbacterium, as determined by 16S rRNA gene sequence analysis. Metabolites produced by DBT desulfurization were identified by GC-MS, and two sulfur-free products, 2-methoxybiphenyl (2-MBP) and biphenyl, were detected in addition to 2-hydroxybiphenyl (2-HBP). This strain can also totally degrade 4,6-dimethyl-DBT, thiophene, benzothiophene and 70% diphenylsulfide.
从污泥中分离出一种能够选择性地对二苯并噻吩（DBT）进行脱硫的新型细菌菌株。通过16S rRNA基因序列分析确定，这种命名为ZD-M2的菌株与微杆菌属的成员聚类关系最为密切。利用气相色谱-质谱联用仪（GC-MS）对DBT脱硫产生的代谢产物进行了鉴定，除了2-羟基联苯（2-HBP）外，还检测到了两种无硫产物，即2-甲氧基联苯（2-MBP）和联苯。该菌株还能够完全降解4,6-二甲基-DBT、噻吩、苯并噻吩以及70%的二苯硫醚。
