Effect of Light-Activated Hypocrellin B on the Growth and Membrane Permeability of Gram-Negative Escherichia coli Cells
Figure 2
Membrane permeability of E. coli cells was measured using flow cytometry with PI staining after photodynamic treatment of hypocrellin B (25 μM), in which the energy density of blue light was 12 J/cm2. (a) Sham control; (b) hypocrellin B treatment alone; (c) blue light irradiation alone; and (d) photodynamic treatment of hypocrellin B.
