Xanthine oxidase activity of arthrobacter x-4 cells immobilized in glutaraldehyde-crosslinked gelatin

Abstract

Cells of Arthrobacter X-4 were immobilized by entrapment in gelatin crosslinked with glutaraldehyde. The xanthine oxidase activity and stability were determined at various temperatures. In comparison with bovine milk xanthine oxidase the bacterial enzyme is more stable and has a different substrate specificity. 1-Methylxanthine was oxidized on a preparative scale.
