โœฆ Synopsis

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.mobilis, there was a decline of approximately 30% in activity after 800 h operation.

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
