ABSTRACT
Immobilization of the bacterium Agrobacterium tumefaciens UP-3 was studied in this paper. The results showed that the immobilized cells with the mixture of polyvinyl alcohol (PVA) and sodium alginate (SA) as the immobilizing carrier had good biodesulfurization characteristics; The optimum operation immobilization conditions were 4℃, the total concentration of PVA and SA being 7%(wt), and the concentration of cells being 0.05 g/mL. When DBT addition was 2.7 mmol/L, the DBT degradation of immobilized cells was above 60% while that of resting cells is 13%. The optimum degradation time and temperature of immobilized cells were 5d and 28℃~32℃, respectively.
