Biodesulfurization of benzothiophene and dibenzothiophene by a newly isolated Rhodococcus strain
Abstract
Rhodococcus sp. KT462, which can grow on either benzothiophene (BT) or dibenzothiophene (DBT) as the sole source of sulfur, was newly isolated and characterized. GC and GC-MS analyses revealed that strain KT462 has the same BT desulfurization pathway as that reported for Paenibacillus sp. A11-2 and Sinorhizobium sp. KT55. The desulfurized product of DBT produced by this strain, as well as other DBT-desulfurizing bacteria such as R. erythropolis KA2-5-1 and R. erythropolis IGTS8, was 2-hydroxybiphenyl. A resting cells study indicated that this strain was also able to degrade various alkyl derivatives of BT and DBT.
