Diffusion of proteases in calcium alginate beads.
Diffusion of proteases from Bacillus subtilis and Serratia marcescens within calcium alginate beads has been assayed, and the experimental data fitted into a mathematical model for diffusion into a finite volume liquid medium. Values of effective diffusivity were calculated for the studied proteases and compared with the available data in the literature for molecules of lower molecular weight.
