Long-term repeated biodesulfurization by immobilized Rhodococcus erythropolis KA2-5-1 cells.

In this study, biodesulfurization (BDS) was carried out using immobilized Rhodococcus erythropolis KA2-5-1 in n-tetradecane containing dibenzothiophene (DBT) as a model oil (n-tetradecane/immobilized cell biphasic system). The cells were immobilized by entrapping them with calcium alginate, agar, photo-crosslinkable resin prepolymers (ENT-4000 and ENTP-4000), and urethane prepolymers (PU-3 and PU-6); and it was found that ENT-4000-immobilized cells had the highest DBT desulfurization activity in the model oil system without leakage of cells from the support. Furthermore, ENT4000-immobilized cells could catalyze BDS repeatedly in this system for more than 900 h with reactivation; and recovery of both the biocatalyst and the desulfurized model oil was easy. This study would give a solution to the problems in BDS, such as the troublesome process of recovering desulfurized oil and the short life of BDS biocatalysts.[1]
