Elastic and inelastic light scattering from single bacterial spores in an optical trap allows the monitoring of spore germination dynamics
Peng, Lixin; Chen, De; Setlow, Peter; Li, Yong-Qing (East Carolina University, 2009-05-15)Raman scattering spectroscopy and elastic light scattering intensity (ESLI) were used to simultaneously measure levels of Ca-dipicolinic acid (CaDPA) and changes in spore morphology and refractive index during germination ... -
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 ...
