title: Biodesulfurization of dibenzothiophene with Rhodococcus erythropolis ATCC 53968 and its mutant in an interface bioreactor.
abstract: An interface bioreactor was used in the biodesulfurization (BDS) of dibenzothiophene (DBT) with Rhodococcus erythropolis ATCC 53968. Although this strain could efficiently degrade DBT to 2-hydroxybiphenyl (2-HBP), the microbial film peeled off from the surface of the carrier (agar plate) to an organic phase (dodecane or tetradecane). To overcome this problem, a UV mutant, which strongly adhered to the carrier surface, was obtained by a new screening method. The best UV mutant (UM-021) could efficiently catalyze the BDS and the microbial film did not peel off from the surface of the carrier to tetradecane layer.
