In this work is reported the urease immobilized on magnetically separable polyaniline nanofibers to improve the enzyme activity. Immobilized urease shows good activity as 5times more than free urease. The immobilized urease showed improved stability and recyclability. PAMP-urease showed only a 3~5% decrease in activity after 1 months of vigorous shaking conditions (200 rpm) and at room temperature (25oC). After 10 times recycle, the residual activities of PAMP-urease was 92%.
