FIG 2.

Germination of B. cereus gerP spores in response to nutrient and nonnutrient germinants. Spores at an OD₆₀₀ of 1 were suspended in buffer supplemented with defined germinants and the resultant changes in absorbance monitored, as described in Materials and Methods. For germinants: circles, 100 mM alanine (ala) (red, wild type; blue, gerP); triangles, 50 mM CaDPA (red, wild type; blue, gerP); squares, 1 mM dodecylamine (dod) (red, wild type; blue, gerP). The + sign represents wild-type spores in buffer without germinant.
