Abstract
IN the course of studies involving the physico-chemical characterization of a proteolytic enzyme from a strain of B. subtilis (NOVO enzyme), viscosity measurements of the protein in concentrated urea and lithium bromide solutions were undertaken. For these studies, a 1 per cent solution of the protein was employed, and outflow times were measured at 20.0° in a modified Ostwald viscometer.
