Biofilm formation by Cutibacterium acnes strains HL036PA1 and HL043PA1 in the absence or presence of 100 μg/mL dispersin B. Biofilms were cultured in glass tubes for 3 days, then rinsed with water and stained with crystal violet. Triplicate tubes for each condition are shown. The control tubes at the left (No bacteria) were incubated with sterile broth. These experiments were performed on two separate occasions with similar results. Tubes from representative experiments are shown.
