FIG. 4.
Inhibition of dodecylamine germination by HgCl2. Spores of strains PS832 (wild type) (○ and •) and PS3411 (↑SpoVA) (▵ and ▴) were germinated with 50 μM dodecylamine in 10 mM Tris-HCl (pH 7.5) at 45°C without (○ and ▵) or with (• and ▴) 3 mM HgCl2, and DPA release was measured as described in Materials and Methods.
