Abstract:
To understand the protein-surfactant interactions between naturally derived sophorolipids (SLs) and bovine lactoferrin (bLf), we carried out spectroscopic, microscopic, and biochemical experiments under weakly acidic and neutral pH conditions. Particle size analysis, microscopy, and enzymatic digestion indicated that bLf and SLs interact with each other to form sheet-like and small aggregated structures reflecting the original self-organization of SLs at pH 5.0 and 7.0, respectively. Circular dichroism (CD) showed that SLs did not significantly affect the secondary structure of bLf.
