Summary

A method for the production of spherical alginate gels from few μm up to several mm diameter is described. Alginate beads with diameters from 0.5 to 3 mm are used to immobilize microorganisms as biocatalysts. Micro size alginate gels are used as column packing material for inverse steric exclusion chromatography to determine their pore sizes from dextran standards of known molecular weight. The results indicate that alginate gels have pores which are large enough to release catalytic acting enzymes out of the matrix.
