FIG 3.

Comparison of growth yields and supernatant sialidase activities for F4969 grown for 24 h at 37°C in control DMEM versus DMEM supplemented with different concentrations of Neu5Ac (SA) or d-glucose. (A) Growth yields for 24-h cultures in DMEM supplemented with specified concentrations of sialic acid (SA) or glucose. (B) Sialidase activities in supernatants from 24-h cultures. The data shown in each panel are mean values for three independent experiments. The error bars indicate standard deviations. *, P < 0.05 compared to the control.
