Lactoperoxidase System Effects on Escherichia Coli K-12 in the Manufacture of a High Moisture and High pH Cheese (Queso Fresco)
<p><strong>The lactoperoxidase system, a naturally occurring antibacterial system in bovine milk, was evaluated as an additional food safety hurdle in a cheese that can support the growth of pathogenic microorganisms. Lactoperoxidase is not completely inactivated at pasteurization temperatures; …

Culinology applications to a convenient and economic frozen dinner set
… methods, such as gelling properties, use of the lactoperoxidase system, sensory analysis, and food engineering. The result is a frozen three-course meal that can be cooked at home but can rival the quality of an up-scale restaurant.

The Membrane Polypeptides of the Vacuolar System: Composition and Recycling
… study the nature of the phagolysosomal membrane. Lactoperoxidase (LPO) is covalently coupled to carboxylated latex spheres (LPO-latex) in a stable enzymatically active form. The addition of LPO-Iatex to cultured macrophages leads to their rapid attachment, ingestion, and enclosure in a plasma …

Electron paramagnetic resonance and resonance Raman spectroscopic investigations of the ferric ligand complexes and the oxidized intermediates of catalase and bromoperoxidase
… obtained are similar to those observed for lactoperoxidase and hog intestinal peroxidase. A band at 264 cm$\sp{-1}$ is tentatively assigned to an iron-imidazole stretch arising from the proposed histidine fifth ligand. The oxidized intermediates present in the reaction cycles of the two …

A study of the aggregating cationic antibacterial proteins and peptides in bovine seminal plasma
… systems like the myeloperoxidase- and lactoperoxidase-mediated system, and two complement systems. Also, a number of mammalian cationic proteins and peptides have been found to have antibacterial properties. The antibacterial activity in bovine seminal plasma has been reported to be due …

An investigation into the structure and functional aspects of the cell wall of Desulfovibrio
… OMP la and lb which comigrate in PAGE. 1251 lactoperoxidase labelling of whole cells shows proteins of OMP 1 and 3 mobility to be exposed on the cell surface. OMPs do not show hydrogenase activity and this enzyme is inactive in C-Fe cells. Numerous minor proteins are present in C+Fe OM but …

Evolutionary and Paleobiochemical Analyses of Heme Peroxidases
… (MPO), eosinophil peroxidase (EPO), lactoperoxidase (LPO) and thyroid peroxidase (TPO).These comprise a functionally diverse multigene family of enzymes associated with such diseases as asthma, Alzheimer’s disease and inflammatory vascular disease. This study has determined how the …

Isolation of immunoglobulins from cheese whey and milk using ultrafiltration and immobilized metal affinity chromatography
… purity. About 152 mg of lactoferrin and 90 mg of lactoperoxidase could be isolated along with the IgG. By using concentrated whey instead of unconcentrated whey, the time required to apply the whey was reduced proportionally to the concentration factor. Whey could be concentrated up to 30 times …

Untersuchungen zum Insulinbindungsbereich des Insulin-IGF-I-Rezeptorsystems mittels kovalenter Markierung
… was iodinated with Chloramin T as well as with Lactoperoxidase/H2O2. Incorporation rates were 80-90% for B29-Asa-Insulin and 60-70% for B29-Atf-Bct-Insulin. 3. Culturing NIH-3T3 Cells, which permanently over expressed the studied receptors, was performed according to standard procedures. Prior …

On-farm fractionation of milk components
… have high commercial value. Lactoferrin (LF) and lactoperoxidase (LP) were used as model proteins for extraction using cation exchange chromatography. Laboratory fractionations showed that milk could be processed by conventional column chromatography without excessive column backpressures if resin …

Studies on the Complement Receptor of a Human Lymphoblastoid Cell Line
… to identify the C3d receptor molecule(s), the lactoperoxidase-mediated iodination procedure of Hubbard and Cohn (1975a) was slightly modified for 8866 cells, and the major iodinatable surface proteins of these cells defined. Three major species, with molecular weights of approximately 11,000, …

Whey Protein Fractionation Using Membrane Separation Technology
… Bovine Serum Albumin (BSA), Lactoferrin (LF), Lactoperoxidase (LP), and Immunoglobulins (IgG). In order to realize the true functional, nutritional as well as economic value of these specialty whey protein fractions, it is essential to process the whey into pure/enriched protein products. …
