Determination of effective diffusion coeficient of immobilized baker's yeast invertase in various concentration of PVA-alginate matrix

Baker's yeast invertase is immobilizzed in PVA-alginate matrix using an improved method PVA beads were prepared by adding calcium alginate to improve its stability, mechanical and chemical properties. Boric acid was used as the cross-linking agent and additional chemicals consisteing of 10% bor...
