Survival and sealing seem to involve branch points. Effects of lysozyme pulsing on the ΔftsZ mutant (a) and wild-type (b, c) cells in the CellASIC ONIX microfluidic chamber. Cells were grown with TSB media. Red arrowheads indicate branch sites; yellow lines highlight presumable cell division sites; and white arrows show sites of cell regrowth. Scale bars = 5 µm. d, e Brightfield (left panels) and FM4-64 stained (right panels) of wild-type (d) and ΔftsZ mutant (e) cells. Scale bar = 5 µm
