Whole cells of the phytopathogenic Erwinia chrysanthemi strains were immobilized in k-carrageenan and grown in high-calcium Xanthomonas campestris medium containing sodium polypectate as carbon source. All the strains used survived 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 could 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 governing the biosynthesis of virulence factors by this bacterium. Journal of Industrial Microbiology & Biotechnology (2001) 27, 215–219.
