Improvement in the yield of lipophilized lysozyme by the combination with Maillard-type glycosylation.

Hen egg white lysozyme was modified using the Maillard-type glycosylation method prior to the lipophilization with palmitic acid. The yield of lipophilized lysozyme significantly increased by the pre-glycosylation of the protein. The lipophilized lysozyme derivative was separated into two main fractions with different level of glycosylation. All fractions showed a strong antimicrobial activity against Gram-negative bacteria, Escherichia coli. The lipophilization of the lysozyme combined with glycosylation is a promising method for potential industrial applications of the lysozyme due to the enhanced antimicrobial activity and the improved yield.
