Effect of Light-Activated Hypocrellin B on the Growth and Membrane Permeability of Gram-Negative Escherichia coli Cells
Figure 4
The ultrastructural morphology of E. coli cells was observed under a transmission electron microscopy (TEM) after photodynamic action 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 (×30000).
