Apo, holo, native-type of lactoferrin showed a similar pattern of circular dichroism(CD) spectra. Lactoferrin appeared to interact more easily with negatively charged liposome than neutral liposome. Holo-type of lactoferrin showed the highest degree of leakage, whereas apo-type of lactoferrin showed the lowest level of leakage. Holo-type lactoferrin could more easily interact with phospholipid liposomes than apo-type lactoferrin, when used as an artificial membrane.

Recent studies have reported that certain lactic acid bacteria and their metabolites, such as exopolysaccharides (EPSs), have immunological effects and can modulate the immune system following oral administration. Lactococcus lactis subsp. cremoris FC is a lactic acid bacteria isolated from fermented milk from Caucasians and has been shown to produce EPSs. In this study, the effects of lactoferrins (apo-lactoferrin, holo-lactoferrin, and native-lactoferrin) and transferrins (apo-transferrin and holo-lactoferrin) on the growth of L. lactis subsp. cremoris FC were examined. The addition of lactoferrins and transferrins to L. lactis subsp. cremoris FC cultures was found to be effective at concentrations of 0.5 or 1 mg/mL.
