^aSpores were germinated in 5 mM Tris-HCl, pH 7.8, for 40 min with 10 mM germinant (50 mM KBr). Spore germination was measured as described in Materials and Methods.

^bRates of spore germination are given relative to the A₆₀₀ loss (65%) for B. megaterium QM B1551 spores in 10 mM glucose, which was set at 100. This value is equivalent to 100% germination after a 40-min incubation. Values are the means of at least duplicate experiments; standard deviation was ≤5% of the mean, except where indicated in parentheses.
