| Abstract: | Summary Diffusion measurements of glucose in a crosslinked water-swollen protein matrix containingStreptomyces thermovulgaris strain 127, are described. Solute diffusion coefficients in the gel phase were found to be considerably lower than for free diffusion. The range of diffusion coefficients was 0.83×10−10 to 2.68×10−10m2/s at corresponding ratios to free diffusion values 0.11 to 0.38. It is shown that polymer structure does not pose any significant effect on mass transfer for the small glucose molecule. |
