摘要: A novel enzyme membrane reactor with sandwich structure has been developed by confining glucosidase between two sheets of ultrafiltration membranes to effectively convert maltose isomaltooligosaccharides (IMOs). The hydrophilic membranes, which were prepared phase inversion method using PES as bulk polymer and Pluronic F127 both surface modification pore formation agent, exhibited the desirable adsorption-resistant property. scanning electron microscopy (SEM) photographs showed that PES/Pluronic packed tightly was kept in a free state within nanoscale space. When weight ratio 30%, could be completely rejected membranes. Due structuring high hydrophilicity surface, conversion yield reached 100% 58% under optimum experimental conditions (pH 6.0, 50 degrees C), respectively. (C) 2010 Elsevier Ltd. All rights reserved.
