The aim of this study was two-fold: firstly, to study the effect of high fluoride concentrations on carbohydrate metabolism in Streptococcus mutans present in biofilms on hydroxyapatite; and, secondly, to evaluate the effect of fluoride-bound hydroxy

The potential pathogenic role of mutans streptococci in the etiology of dental caries is well-documented. Mutans streptococci are sensitive to chlorhexidine (CHX), and several methods for the clinical use of CHX have been described. An important targ

An arginine carboxypeptidase was isolated from the cell walls ofStreptococcus mitis ATCC 15909 by mutanolysin extraction of the walls. The enzyme was purified 32-fold by gel filtration on Sephacryl S-300, affinity chromatography on Arginine-Sepharose

An aminopeptidase isolated from the cytoplasmic fraction of a cell extract of Streptococcus mitis ATCC 903 was purified 330-fold by ion-exchange chromatography, gel filtration, and hydroxyapatite chromatography. The partially purified enzyme had a br

Arginine catabolism via the arginine deiminase pathway was found in Streptococcus sanguis 903. Citrulline and ornithine were released from resting cells incubated with arginine, arginine-containing peptides, or saliva. Maximum arginine catabolism by

beta-Fructofuranosidase activity was found to be cell-bound in Streptococcus mitis ATCC 903. The following evidence suggests that induction functions as a regulatory mechanism for beta-fructofuranosidase in S. mitis: (1) on transfer of glucose-grown

Two fractions of water-soluble glucans with different molecular weight were produced by Streptococcus mutans IB. The larger glucan had a molecular weight of about 40,000. The molecular weight of the small glucan was estimated to be 4,100 by gel filtr
