Comparison of Dextranases for their Possible Use in Eliminating Dental Plaque

Abstract
Three dextranases produced by Penicillium were compared with respect to their activity and stability at different pH values, to their molecular weight, to their affinity to Sephadex G-25, and to their action on dextrans that contain varying proportions of different bonds. The enzyme produced by P funiculosum strain NRRL 1768 is considered a suitable enzyme for use in an enzymatic dental plaque elimination system.
