Lysozyme- is an enzyme present in milk and egg whites.
Lysozyme kills bacteria by disrupting the formation of a glycosidic
bond between the two components of peptidoglycan, a constituent of the
bacterial cell wall. Lysozyme is effective against a number of bacteria
including Escherichia coli and Salmonellae.
Lactoferrin- is an iron binding protein. It is found
naturally in cow and human milk, tears, saliva and in some white blood
cells. Lactoferrin is only partially saturated with iron (5 to 30 percent)
so it has a high affinity towards iron. Because most bacteria need iron
for growth, lactoferrin has the potential to inhibit the growth of bacteria
and kill them by depriving them of iron. Lactoferrin is bacteriostatic
against a wide range of microorganisms including gram-negative (coliforms)
and gram-positive bacteria(Staphylcoccus).
Conclusion- Antimicrobial proteins and enzymes naturally
present in milk have the ability to kill and inhibit a broad spectrum
of bacteria, viruses, and fungi. This system is suitable for a variety
of antimicrobial uses. The Three Point Enzyme System has been tested
to show strong antimicrobial activity against Staphylococcus, E.coli,
Streptococcus, Proteus, Candida, Pseudomonas, Corynebacterium and Malassezia.
