...V. Roger; J. Tenovuo; M. Lenander-Lumikari; E. Söderling; P. Vilja Lysozyme, lactoperoxidase and salivary peroxidase inhibit the metabolism and growth of mutans streptococci, but any possible effects on the adherence of these bacteria are unknown. In this study the effects of lysozyme...

...J.S. van der Hoeven; P.J.M. Camp Mixed continuous cultures of Streptococcus species were obtained, using complex carbohydrate (mucin) as a source of nutrients, to study the ecological effects of oxygen and the lactoperoxidase system. S. mutans NCTC10449 was unable to grow as a pure culture on mucin...

...J. Tenovuo; J. Valtakoski; M.L.E. Knuuttila Lactoperoxidase was shown to be adsorbed by human salivary sediment and hydroxyapatite. Phosphate ions (0.5 M ) effectively regained the adsorbed activity while sodium fluoride (1 mg/l) was less effective. 45% of the total activity was adsorbed...

...H. Hoogendoorn; J.P. Piessens; W. Scholtes; L.A. Stoddard The initial step in the lactoperoxidase (LPO) catalysed oxidation of thiocyanate (SCN –– ) by hydrogen peroxide (H 2 O 2 ) leads to the formation of hypothiocyanite (OSCN –– ), the ion of hypothiocyanous acid. In dilute non-acid solutions...

...J. Tenovuo Both free and adsorbed lactoperoxidase (LPO) were shown to produce the bacterial inhibitor, hypothiocyanite ion (OSCN –– ) in approximately equal capacity. In human salivary sediment OSCN –– ions are rapidly decomposed, even at pH 7.0 were OSCN –– ions otherwise are stable, indicating...

... with peroxide alone or with a combination of peroxide and SCN - . The most effective initial H 2 O 2 concentration was 700 μ M . Higher concentrations caused a rapid loss in the amount of OSCN - . In contrast to expectations, supplementation of saliva with excess lactoperoxidase resulted in decreased generation...
