Whereas the bacteriocin activity of eight strains of Streptococcus mutans was unaffected by growth in the presence of sucrose, such a medium rendered five S. mutans and one S. salivarius indicator strains unsusceptible to the bacteriocins. In contrast, the susceptibility of three S. faecalis and one S. pyogenes strains was unaltered when these indicators were grown in the presence of sucrose. S...
