FIG. 3.
Time-resolved changes in biovolumes (μm3 per field of view) of S. oralis (So), A. oris (Ao), and Veillonella sp. (Va) following 4 h and 18 h of incubation in 25% saliva-fed flow cells. The biovolume values are for the single-species-inoculated flow cells (see Fig. 2). An asterisk indicates statistically significant increases (P < 0.05) in bacterial growth. Error bars indicate standard deviations.
