<i>T. denticola</i> growth and glycine.

<p>(a) The concentration of free glycine in <i>T. denticola</i> culture (black square; left axis). <i>T. denticola</i> growth curve in the same medium (black inverted triangle; right axis). Data points are the mean and standard deviation of three biological replicates. (b) Glycine (10 mM) was added to OBGM either before inoculation with <i>T. denticola</i> (black square, open arrow) or at 96 h after inoculation (black triangle, filled arrow) and bacterial growth was determined by A_{650 nm} measurement. <i>T. denticola</i> culture with no added glycine (white circle). Results are expressed as mean ± standard deviation obtained from eight replicates.
