Abstract

Pseudomonas moraviensis AN-5 isolated from contaminated sludge could utilize aniline as a sole carbon and nitrogen source. The aniline degradation by cells immobilized in alginate, polyvinyl alcohol (PVA) and polyurethane foam (PUF) was significantly better than freely suspended cells. The immobilized AN-5 degraded aniline nearly completely at the initial concentration of 22 mM by 48 hr of incubation. Compared to other binding materials, PUF-immobilized cells were more stable in aniline biodegradation in reused cycles. Moreover, immobilized cells could be stored for three months at 4^oC with little reduction of the aniline degradation capacity. These results revealed that PUF-immobilized P. moraviensis AN-5cells has enhanced aniline biodegradation activity.
