Abstract: | Statistical models concerning partitioning of pectinase in polyethylene glycol 1000/Na2SO4 aqueous two-phase system were established with response surface methodology. Concentrations of polyethylene glycol 1000 and
Na2SO4 were selected as independent variables to evaluate their impact on parameters of partitioning in aqueous two-phase system—the
partition coefficient of pectinase, purification factor and pectinase yield. An experimental space where over 2.5-fold purification
was achieved, followed by over 90% yield of pectinase. The established models showed good prediction of partitioning parameters. |
