TLDR
Anaerobic microbial biodegradation of Dibenzothiophene (DBT) was studied using thermophilic bacteria obtained from crude oil as mentioned in this paper, and a mixed culture was obtained that degraded 98% of DBT at 0.5 mg ml−1 at 65 °C over 15 days both in the presence and in the absence of Methyl Viologen.Abstract:
