Application
Lactoperoxidase from bovine milk has been used as a standard for milk lactoperoxidase to study the role of H2O2 in the inhibition of Staphylococcus aureus growth by Lactococcus garvieae in the presence of lactoperoxidase in raw milk. It has also been used in lactoperoxidase-mediated iodination to prepare radiolabeled peptides.

Handling Precaution
Lactoperoxidase contributes to the antimicrobial system of milk by inactivating a wide range of micro-organisms. This lactoperoxidase-mediated antimicrobial system is also identified in human secretions such as tear-fluid, saliva, and milk. Lactoperoxidase catalyzes the oxidation of molecules by releasing H2O2. The product exhibits antimicrobial activity.
Lactoperoxidase catalyzes the oxidation of iodide to iodine by hydrogen peroxide. This activity provides a gentle, specific alternative to chloramine T for the radioiodination of proteins and DNA.
