| Abstract: | Summary The possibility of using polyurethane foam as a support for the immobilization ofZymomonas mobilis cells to carry out sucrose conversion to ethanol was investigated. Sucrose hydrolysis efficiencies of 90% and higher, volumetric reactor productivity of 20 gL–1h–1 and final ethanol concentration of 6.3% (v/v) at a dilution rate of 0.4 h–1 show the good performance of polyurethane foams for whole cell immobilization. |
