  • How Moist Heat Kills Spores of Bacillus subtilis 

    Coleman, William H.; Chen, De; Li, Yong-Qing; Cowan, Ann E.; Setlow, Peter (East Carolina University, 2007-12)
    Populations of Bacillus subtilis spores in which 90 to 99.9% of the spores had been killed by moist heat gave only two fractions on equilibrium density gradient centrifugation: a fraction comprised of less dense spores ...

  • Role of Dipicolinic Acid in the Germination, Stability, and Viability of Spores of Bacillus subtilis 

    Magge, Anil; Granger, Amanda C.; Wahome, Paul G.; Setlow, Barbara; Vepachedu, Venkata R.; Loshon, Charles A.; Peng, Lixin; Chen, De; Li, Yong-Qing; Setlow, Peter (East Carolina University, 2008-07)
    Spores of Bacillus subtilis spoVF strains that cannot synthesize dipicolinic acid (DPA) but take it up during sporulation were prepared in medium with various DPA concentrations, and the germination and viability of these ...
