Continuous enzymatic production of lactobionic acid using glucose-fructose oxidoreductase in an ultrafiltration membrane reactor
Glucose-fructose oxidoreductase from Zymomonas mobilis catalyzed the oxidation of various aldose sugars to the corresponding aldonic acids. The enzyme was used for the selective and high-yield conversion of lactose to lactobionic acid in batch, fed-batch and continous reaction mode. A productivity of 110 g L-1 d(-1) was obtained in an ultrafiltration membrane reactor, operated for 70 h.
