β¦ Synopsis
Cell retention
and ethanol production using the flocculent bacterium Zymomonas mobilis NPRL B-12526 were studied in three bioreactor configurations.
The flocculent growth characteristic of this strain and a special reactor design were combined to achieve relatively high cell concentrations in a continuous bioreactor for the conversion of glucose to ethanol.

Studies have been carried out with a highly productive strain of Zymomonas mobilis in an immobilized cell reactor using both Ca alginate and K-carrageenan as supporting matrices. Productivities above 50 g/I/h have been found at ethanol concentrations in excess of 60 g/l. With immobilized cells of Z
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 immo
