FIG. 2.

Impacts of urea and urease inhibitor on survival of BHI-grown stationary-phase cells of B. cereus ATCC 10987 exposed to pH 4.5. Three exposed cultures, without added urea, with 10 mM added urea, and with added urea and flurofamide, as indicated at the right, were diluted and droplet plated. The time of low-pH exposure is depicted at the top of each plate, and the dilution factors are indicated below the plates. This experiment was performed in triplicate, and all replicates showed similar results; a typical result is shown here.
