Various types of common available carrageenans were screened and utilized to immobilize cells of Zymomonas mobilis ATCC 10988. The immobilized cells were used in an ordinary batch bioreactor system and a specially designed fixed-bed bioreactor to produce EtOH from glucose. Both surface-hardened and nonhardened carrageenan beads were tested containing immobilized cells ranging 50-100 g dry weight cell/L bead volume. The highest volumetric productivity of EtOH obtained was 101 g EtOH/L-h.
