Summary
Columnar reactors containing immobilized cells of Zymomonas mobilis were utilized for the continuous production of ethanol from glucose. Two different immobilization strategies were investigated. In one case, cells were entrapped in borosilicate glass fiber pads, while in the other, cells were immobilized via flocculation. The reactors were operated in both the fixed-bed and expanded-bed manner. Ethanol productivities as high as 132 g/l·h were achieved. Data obtained from studies employing 5.0 and 10.0% glucose concentrations are presented. Problems encountered during the operation of the continuous, immobilized cell reactors are discussed.
