Abstract

Gordona sp. MS6, desulfurizing petroleum, can convert dibenzothiophene (DBT) to 2-hydroxybiphenyl (2-HBP) and sulfate. In this study, the effect of DBT degradation product on DBT desulfurization activity was investigated. When $Na_2$SO$_4$ and DBT were simultaneously added in the medium sulfur sources, specific growth rate of strain MS6 was doubled compared to not adding $Na_2$SO$_4$. But, sulfate inhibited DBT desulfurization rate, furthermore, when 0.05 g/L $Na_2$SO$_4$ was supplied DBT desulfurization rate decreased down to 40%. When 2-HBP and its derivative, 2, 2'-dihydroxybiphenyl (DHBP) were not added, DBT desulfurization rate was 5.0 $\mu$mol L$^{-1}$ㆍh$^{-1}$. With the increase of 2-HBP and DHBP concentration, DBT desulfurization rate was decreased. No DBT desulfurization activity of Gordona sp. MS6 was observed when initial concentration was over 0.15 mM 2-HBP and 0.8 mM DHBP [Gordona sp., Desulfurization, Dibenzothiophene, 2-Hydroxybiphenyl, Sulfate].
