Abstract
Whole cells of the phytopathogenic Erwinia chrysanthemi strains were immobi lized in k-carrageenan and grown in high-calcium Xanthomonas campestris med ium containing sodium polypectate as carbon source. All the strains used su rvived immobilization into k-carrageenan beads. Immobilized E. chrysanthemi strains displayed higher pectolytic and proteolytic enzyme activities than free cells in liquid suspension. Carrageenan immobilization techniques cou ld provide a system to mimic the conditions of E. chrysanthemi cells in the infected plant tissue. This could prompt a thorough study of the factors g overning the biosynthesis of virulence factors by this bacterium.
