• Pectate oligosaccharides were separated from enzymatically hydrolyzed pectate by using ultrafiltration(UF) and nanofiltration(NF) membranes. The UF treatment was performed at a transmembrane pressure of 0.15MPa and flow velocity of 0.6 m・s^<-1> and nonhydrolyzed pectate was removed almost completely. The NF treatment was carried out at a transmembrane pressure of 0.5 MPa and flow velocity of 0.6 m・s^<-1> and large amounts of monogalacturonic acid and sucrose, the contaminants included in the UF permeate were separated. Pectate oligosaccharides obtained by the diafiltration treatment of the NF concentrate were mainly composed of di- to pentasaccharides and exhibited root-growth-promoting activity in lettuce(approximately 1.8-fold) compared with the control. In particular, penta-, tetra-, and disaccharides were found to have strong activity.
