title: Metabolic characteristics of bacterial cells entrapped in beaded calcium alginate and/or pectate gels.
abstract: A mixture of heterotrophic bacteria and collection strains of Escherichia coli and Pseudomonas fluorescens were immobilized in calcium alginate or pectate gels. Comparison of respiratory activity, substrate uptake and biosynthetic capacity of immobilized cells showed that both types of carriers permit a prolonged preservation of metabolic activity but the transfer of substances through the gel is faster in the pectate. Morphological changes include some intracellular structures, partial shrinkage of the plasma membrane of immobilized cells, and transformation of a rod-like cell shape to an oval one.
