FIG. 2.

Effect of polyP on the outgrowth of B. cereus spores. Liquid media were inoculated with 2 × 10⁶ heat-induced spores per ml, and different amounts of JOHA HBS polyP (0.05% [■], 0.1% [▴], and 1% [●]) were added at zero time. Dashed line, control culture without polyP. Samples were taken at different times, and outgrowing spores were enumerated (expressed as CFU per milliliter) by plating them onto solid media. The error bars indicate the approximate variability in CFU determinations.
