The effect of titanium on the growth of plaque micro-organisms in vitro.

The effect of titanium on the growth of plaque organisms was studied in vitro. Thioglycollate broth containing either titanium or glass cylinders was inoculated with plaque micro-organisms and incubated aerobically and anaerobically at 37 degrees C for 6 hours. Growth was measured by observing an increase in turbidity of the broth. Cultures grew more vigorously aerobically than anaerobically. In the presence of titanium there was also more growth aerobically than anaerobically. There was no significant difference between the turbidity values obtained in the presence or absence of titanium suggesting that titanium does not influence the growth of plaque micro-organisms significantly.
