Summary
Penicillium chrysogenum spores have been immobilized by adsorption on two grades of wet or dry diatomaceous earth particles, Chromosorb-W and Celite R-633. Almost 90% of the spores were adsorbed within 2 h and those remaining in suspension were removed by washing to minimise the growth of free mycelia. After germination the immobilized biomass was almost independent of the spore loading on the particles and whether or not the spore suspension was added to wet or dry particles. The free biomass obtained was less than 5% of the immobilized biomass.
