## Abstract __Saccharomyces cerevisiae__ cells were immobilized in calcium alginate beads for use in the continuous production of ethanol. Yeasts were grown in medium supplemented with ethanol to selectively screen for a culture which showed the greatest tolerance to ethanol inhibition. Yeast beads

The organism used was Aspergillusfoetoidus (IMI 15954) which produces citric acid when grown on a defined synthetic medium. A preliminary study has been carried out to establish the performance characteristics of the modified CMMFF at various inlet substrate concentrations, dilution rates and biomas
were immobilized by occlusion in pectin gel, no significant changes in their biological activity being observed. The ethanol production rate was found to be negatively affected by the diameter of the beads when the cell concentration in them was high. The fermentative activity was only slightly modi
