Figure 5a. Metabolic activity of adherent Candida on (A) the unmodified PMMA to serve as controls, (B) g-PMMA with 10 bilayers, and (C) g-PMMA with 10.5 bilayers, after two days of incubation in broth solutions (n=4); and 5b, metabolic activity of free floating Candida in the broth solutions with (A) the original PMMA disc, (B) g-PMMA coated with 10 bilayers, and (C) g-PMMA coated with 10.5 bilayers, after two days of incubation (n=4). A higher XTT absorbance indicates a higher metabolic activity of Candida cells.
