โœฆ Synopsis

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/~.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.

Zymomonas mobilis cells were immobilized into small 1 mm diameter beads of Ca-alginate in order to minimize mass transfer limitations and maximize immobilized cell activity. A combination of small bead size with a high cell concentration of 58 g dry wt. cell per lit. bead volume resulted in high et
