Figure 2

Proteolytic activities of Lactobacillus fermentum biofilm populations in the presence or absence of MUC5B mucins. CSLM images showing biofilm cells growing in (a) the presence of a MUC5B environment or (b) a nutrient broth environment. Proteolytic activity was visualized by incubation with a FITC-conjugated casein substrate (green) for 1 hour. Cells were then counterstained using Syto 24 (red). The bar represents 20 μm and the inserts show four-fold enlargements of the main micrographs.
