Abstract

Utilization of synthetic polymeric membrane in the downstream processing of enzyme production is now well accepted due to its effectiveness and ability to generate high yield of product. This study aimed to investigate the effects of polymer concentrations and membrane surface modification on morphology and performance of ultrafiltration membranes for trypsin separation. Three membrane solutions with different polymer concentration of Polysulfone (15% [PSf 15], 17% [PSf 17] and 19% [PSf 19]) were used to prepare asymmetric flat sheets membranes via a simple dry/wet phase inversion technique. The data obtained shows that the permeability coefficient decreased with increasing polymer concentrations. PSf 15 membrane which showed the highest flux and trypsin transmission was subjected to membrane surface modification by chitosan solution.
