FIG. 1.

Effect of inoculum concentration on cell growth under both anaerobic and aerobic gasses with regular (routine) (A) and conditional (B) inoculation. T. denticola cultures with an initial OD₆₆₀ of 0.16 were inoculated into GM-1 medium under the indicated conditions in 6-ml volumes for 72 h of incubation. The regular (routine) inoculum (A) represents ≤10% inoculation (culture volume/broth volume), and the conditional inoculum (B) represents ≥20% inoculation (culture volume/broth volume). Error bars indicate standard deviations.
