Burkholderia sp, a Gram-negative, rod-shaped, aerobe, capable of degrading quinoline was immobilized in calcium alginate gel beads and used for degradation of quinoline in aqueous solution in the reactor. The optimal conditions for immobilization of the microorganism, such as alginate concentration, calcium ion concentration, initial cell loading, hardening time and bead size, were determined with a view to improving the quinoline degradation rate. The characteristics of quinoline degradation by immobilized microbial cells were investigated. The repeated use of immobilized cells for quinoline degradation was performed and the results revealed that the bioactivity of immobilized cells was stable over 100 h in the repeated batch cultivation for quinoline degradation.
