An Important Milk Enzyme: Lactoperoxidase
It has been acknowledged since ancient times that milk and dairy products have a vital role in nutrition and contribute considerably to human health. Because of its content, Because of its content, it has many important effects on the life that include immuno‐ globulins, enzymes, hormones, growth factors, antibacterial agents, fat acids, vita‐ mins, and minerals. Approximately 70 indigenous enz...
متن کاملDirect Capture of Lactoferrin and Lactoperoxidase from Raw Whole Milk by Cation Exchange Chromatography
The production of high-value dairy proteins such as lactoferrin and lactoperoxidase normally requires extensive pre-treatments of milk to remove fat and caseins by centrifugation, precipitation, Ca 2+ chelation and/or filtration. Similarly, fat and caseins are normally removed prior to capture of recombinant proteins from the milk of transgenic animals. Such pre-treatments can result in signifi...
متن کاملAntibacterial activity of the lactoperoxidase system in milk against pseudomonads and other gram-negative bacteria.
Products of thiocyanate oxidation by lactoperoxidase inhibit gram-positive bacteria that produce peroxide. We found these products to be bactericidal for such gram-negative bacteria as Pseudomonas species and Escherichia coli, provided peroxide is supplied exogenously by glucose oxidase and glucose. By the use of immobilized glucose oxidase the bacterial agent was shown to be dialyzable, destro...
متن کاملLactoperoxidase activity in human milk and in saliva of newborn infants.
Human milk and saliva from newborn infants were analyzed for their content of lactoperoxidase and thiocyanate. The activity of lactoperoxidase in infant saliva was variable but generally higher than that found in calf saliva. In contrast, the activity in human colostrum was low ( approximately 5%) compared with that found in cow's milk. The enzyme was resistant to gastric juice. Thiocyanate was...
متن کاملEffect of the lactoperoxidase system on Listeria monocytogenes behavior in raw milk at refrigeration temperatures.
Activity of raw milk lactoperoxidase-thiocyanate-hydrogen peroxide (LP) system on four Listeria monocytogenes strains at refrigeration temperatures after addition of 0.25 mM sodium thiocyanate and 0.25 mM hydrogen peroxide was studied. The LP system exhibited a bactericidal activity against L. monocytogenes at 4 and 8 degrees C; the activity was dependent on temperature, length of incubation, a...
