Abstract

Using microorganisms is another method for removal sulfur from hydrocarbon fractions without converting their carbon structures. Nowadays BIODESULFURIZATION of crude oil fractions is considered as the most important issue. RIPI-S81 is a new DBT-desulfurizing bacterium, which is able to convert DIBENZOTHIOPHENE to 2-hydroxybiphenyl via 4S pathway. This bacterium isolated and depurated by department of microbiology and biotechnology, research institute of petroleum industry in Iran. In this research, we have studied removing sulfur of 4-MDBT (that it is one of alkylated derivatives of DBT) by RIPI-S81. The molecular structures of metabolites from DBT and its derivatives were analyzed using GC-MS. The reduction and conversion of 4-MDBT through the growth phase of bacterium were analyzed by HPLC. Then we obtained growth curve of RIPI-S81 in a medium containing 4-MDBT as a sole sulfur source. RIPI-S81 could desulfurize about 57 % of 4-MDBT during its growth phase in 110 hours via 4S pathway. Resting cells of this bacterium could also desulfurize 4-MDBT.
