Effect of Light-Activated Hypocrellin B on the Growth and Membrane Permeability of Gram-Negative Escherichia coli Cells
Figure 3
Membrane permeability of E. coli cells was measured using confocal laser scanning microscopy with PI staining after photodynamic treatment of hypocrellin B (25 μM), in which the energy density of blue light was 12 J/cm2.
