Effect of heat activation on yields of superdormant sporesa

Bacillus sp. strain usedGerminant usedYield of superdormant spores (%) with:
No activationHeat activation
B. megaterium wild typed-Glucose365
B. megaterium wild typel-Proline475.5
B. subtilis wild typeAGFK4013
B. subtilis wild typel-Valine184
  • a Spores of various species with or without optimal heat activation were germinated with various agents, superdormant spores were isolated, and their yields were determined, as described in Materials and Methods.
