New Composite, Poly(Hydroxyethylmethacrylate-Expanded Perlite), for Single step Separation of Egg White Lysozyme
Abstract
In this study, we
investigated adsorption behaviour of lysozyme on poly(hydroxyethylmethacrylate-expanded
perlite) [P(Hema-Ep)]. For this purpose, we synthesized P(Hema-Ep) composite by
bulk polymerization and it was characterized by SEM, FTIR and swelling
ratio. The fresh chicken egg white
lysozyme was used as a model protein, had an isoelectric point (pI) 10.7 and
molecular weight (MW) 14 kDa. Adsorption
capacity was found 51 mg g-1 at room temperature and in 0.1 M pH=8.0 phosphate buffer.
Experiments on desorption and reusability were also performed. It
appears that P(Hema-Ep) composites can be
used ten times without lost of efficiency.
Lysozyme purification, without causing any denaturation, can be
performed from chicken egg white by using this new synthesized composite in a
single step.
