•The number of alkyl substituents slowed the biodegradation of DBT homologs.•Selective biodegradation occurred in isomers of alkyl DBTs, especially in C2- and C3-DBTs.•The sulfur-shielded isomers are more susceptible to biodegradation than the sulfur-exposed isomers in C2- and C3-DBTs. The biodegrad...
