Effect of germinant receptor levels on yields of superdormant sporesa

Bacillus sp. strain usedRelative GerB* level in sporesbYield of superdormant spores (%)

  • a Spores of various strains were germinated with asparagine, superdormant spores were isolated, and their yields were determined, as described in Materials and Methods.

  • b Values for relative levels of GerB* in spores of these strains are from the literature (26).
