TABLE 2.
Charge [Log(CFU/cm2)] of microorganisms on the glass surface after 24 hr incubation at 30°C. Inocula were resuspended in the proper medium containing 200 mM PB (pH 7.0). All the Ce‐BGs were tested and compared with controls. The reported data are means ± standard deviations of three independent experiments. No significant difference between the H and K series and among controls and Ce‐BGs with different cerium amounts were observed (test‐t and ANOVA, p > .05)
