Paenibacillus sp. strain A11‐2, which had been primarily isolated as a bacterial strain capable of desulfurizing dibenzothiophene to produce 2‐hydroxybiphenyl at high temperatures, was found to desulfurize benzothiophene more efficiently than dibenzothiophene. The desulfurized product was identified as o ‐hydroxystyrene by GC–MS and 1 H‐NMR analysis. Benzothiophene was assumed to be degraded in a way analogous to the 4S pathway, which has been well‐known as a mode of dibenzothiophene degradation. These results suggest that benzothiophene desulfurization may share at least partially the reaction mechanism with dibenzothiophene desulfurization.
