Beta-glucanase productivity improvement via cell immobilization of recombinant Escherichia coli cells in different matrices.

The studies have been performed to analyze the production of beta-glucanase by a recombinant strain of Escherichia coli immobilized in different matrices. Porous sintered glass SIRAN, Ceramic supporting matrices and Broken Pumice stone as well as SIRAN Raschig-rings were examined for the immobilization of whole bacterial cells. The beta-glucanase activity of bacteria immobilized in CeramTec PST 5 (4-5 mm) was very low.
