Abstract

A method for the determination of glucose-fructose oxidoreductase (GFOR) activity in whole cells of Zymomonas mobilis is described. The K m and the theoretical V max for GFOR were 192 g glucose.l(-1) and 17 g gluconic acid.g(-1) cell.h(-1), respectively. The changes in enthalpy (31.1 kJ.mol(-1)), entropy (0.41 kJ.K(-1)), and Gibbs free energy (-97.5 kJ.mol(-1)) related to glucose to gluconic acid conversion were also determined.
