Transmission electron photomicrographs: Staphylococcus aureus 209P (top) and Pseudomonas aeruginosa E7 (bottom) biofilm in tubing: (a, e) before treatment, (b, f) after a 5-min and (c, g) 30-min treatment with peracetic acid (PAA), and (d, h) after a 30-min treatment with glutaraldehyde (GA). Compared with GA, treatment with PAA resulted in gradual cell-structure collapse (S. aureus) and evident bleb-like bulges indicating cell damage (P. aeruginosa)
