Three strains of Streptococcus salivarius including a recent clinical isolate were found to possess Ca2(+)-dependent fructosyltransferase (FTF) activity. The extracellular FTF activity of cells grown on sucrose increased as much as 9-fold compared with cells grown on either glucose, fructose or galactose. This increase in activity was due not to induction of FTF by sucrose, but to the release of the cell-bound form of the enzyme. Studies with washed cells of S. salivarius ATCC 25975 showed that… CONTINUE READING
