Effects of Chitosan on Candida albicans: Conditions for Its Antifungal Activity

Figure 4

Effects of chitosan on the potential of C. albicans ATCC 10231 cells. The mobility of the cells was measured against time in a Zeta Meter ZM-75 cell electrophotemeter, to calculate the electrophoretic mobility. From this last parameter, the zeta potential was obtained by the Helmholtz-Smoluchowski equation. The medium (13 mL final volume) contained 10 mM MES-TEA buffer, 2 mM glucose, 12.5 mg of cells (wet weight), and the indicated amounts of chitosan. The potential difference applied was 100 V.
