英文摘要: A variety of natural polymers are considered suitable for cell entrapment. Pectin, a natural polysaccharide found in the cell walls of all higher terrestrial plants, presents great potential for cell encapsulation because of its ability to form gels. In this study, we investigated the influences of intrinsic and extrinsic factors on the formation and properties of calcium pectate (CP). Beads of CP prepared with 30-35% methyl esterification presented improved gel properties. The molecular weight (M-w), calcium content, and gel time did not significantly affect the gel properties. The gelling properties, sphericity factor (SF), and swelling ratio were significantly influenced by the degree of methyl esterification (DE) and pectin concentration. The DE (<40%), M-w, and calcium concentration had negative effects on the SFs of CP beads. Moreover, increases in the DE (<40%) and pectin concentration increased the swelling ratio. The C3A cells encapsulated in optimized CP beads maintained good viability and proliferation for up to 2 weeks. In conclusion, CP beads are a potential encapsulation material for cell immobilization and application in related fields. (c) 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45685.
