Lysozyme separation by hollow-fibre ultrafiltration

This paper discusses the purification of lysozyme from chicken egg white using hollow-fibre ultrafiltration (30kDa MWCO, polysulphone membrane). Lysozyme is preferentially transmitted through the membrane while the membrane largely retains other egg white proteins. Improvement in system hydrodynamics resulted in an increase in permeate flux while lysozyme transmission remained unaffected, leading to higher productivity. The percentage purity of …
