FIG 4.
S. mutans growth is unaffected by the presence of salivary mucins. A growth curve of S. mutans in BHI with 1% sucrose (SMedium), BHI with 1% sucrose and 0.3% mucins, or BHI with 1% sucrose and 0.3% methylcellulose indicates that the presence of mucins and methylcellulose does not alter the growth of S. mutans. Error bars represent SDs.
