  • a Spores of different strains were germinated with various agents, germination was measured by the release of DPA, and the maximum rates of germination were calculated as described in the text.

  • b Values are the averages of duplicate measurements on three different spore preparations. Individual values differed by ≤35% from the average values. d-ala, d-alanine; d-glu, d-glucose; and l-asn, l-asparagine.

  • c This value was set at 100%.
