Jones-Ray effect on the organization of lysozyme in the presence of NaNO₃ at an air/water interface: is it a cause or consequence?

Abstract

Interfacial rheology confirms the Jones-Ray effect resulting from a synergy between lysozyme and NaNO3 at an air/fluid interface.

Adsorption, Surface Viscoelasticity, and Foaming Properties of Silk Fibroin at the Air/Water Interface

“…Increasing ion valence or concentration in a certain range can enhance the protein adsorption and the foam stability, due to the decrease in net surface charge, the promotion of protein-protein interactions and the increase in surface dilatational elasticity [5,11,14]. For example, lysozyme in its native state forms a fragile monolayer film, but the addition of NaNO 3 leads to a thick and strongly viscoelastic film, in which lysozyme transforms its secondary structure from helix to β sheet [15]. Similar to salts, surfactants can also accelerate the interfacial adsorption and enhance the foamability of proteins.…”
