| DK1622 | Wild type | 66 ± 4 | 100 ± 6b |

a
Sporulation frequencies are presented relative to the sporulation level in the wild-type strain DK1622 after 120 h of starvation. Values are means and standard deviations from three experiments.
b
The absolute sporulation level of DK1622 was 14.7% ± 1.0% at 120 h.
c
Spores of SA2118 germinated at a threefold-lower frequency than wild-type spores.
