✦ Synopsis

Soil was incubated in mineral medium with Prudhoe Bay crude oil at 20 °C under shake-flask conditions. The aromatic fractions of oil extracted from these cultures were analyzed by capillary GC using a S-specific detector. Without nutrient supplementation, these cultures degraded alkyl benzothiophenes, dibenzothiophene, the Cl-dibenzothiophenes and some C2-dibenzothiophenes after 27 days incubation. When supplemented with N and P, most of the C2-dibenzothiophenes and some C3-dibenzothiophenes were also degraded. The following orders of susceptibility to microbial attack were observed in homologous series: (a) C2-benzothiophene > C3-benzothiophenes , (b) dibenzothiophene > C1-dibenzothiophenes > C 2dibenzothiophenes > C3-dibenzothiophenes.
