FIG. 7.

Release of small molecules during spore germination by dodecylamine. Spores of strain FB113 (cwlJ sleB) were germinated at 37°C with 0.5 mM dodecylamine in 10 mM KPO₄ buffer (pH 7.4), and levels of (A) total DPA and free glutamic acid in the culture and (B) glutamic acid and DPA in the supernatant fluid from spores were measured as described in Materials and Methods. Symbols: ○, glutamic acid; •, DPA.
