Physical Characterization of Biocatalyst Particles Obtained from Polymer Entrapment of Whole Cells
Various polymeric network systems have been developed for whole cell entrapment. Three test methods: a) compressibility of a single particle, b) pressure drop of a packed bed and c) abrasion behavior in a stirred vessel-are described which provide a quantitative determination of the performance of such biocatalysts in technical application. The fact will be demonstrated, that not only the nature of the polymeric matrix itself, but also, the type and amount of immobilized cells are property determinating factors.
