Fig. 5. Psl is holding multicellular aggregates together.
Representative phase-contrast microscopy images (×20) of a control sample (a) and a sample treated with the glycoside hydrolase PslG (b). c Aggregate size distributions for the control and PslG-treated samples. Samples were incubated for 3.7 h, PslG was added (see “Methods”), and samples were imaged 45 min later. Note there was a 20 min lag between imaging the control (4.1 h) and the enzyme-treated (4.4 h) samples. Scale bar = 150 μm.
