Kinetics of Germination of Individual Spores of as Measured by Raman Spectroscopy and Differential Interference Contrast Microscopy
(2013)
Geobacillus stearothermophilus is a gram-positive, thermophilic bacterium, spores of which are very heat resistant. Raman spectroscopy and differential interference contrast microscopy were used to monitor the kinetics of ...
Role of Dipicolinic Acid in the Germination, Stability, and Viability of Spores of Bacillus subtilis
(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 ...
Elastic and inelastic light scattering from single bacterial spores in an optical trap allows the monitoring of spore germination dynamics
(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 ...
Levels of Ca2+-Dipicolinic Acid in Individual Bacillus Spores Determined Using Microfluidic Raman Tweezers
(East Carolina University, 2007-07)
Pyridine-2,6-dicarboxylic acid (dipicolinic acid [DPA]) in a 1:1 chelate with calcium ion (Ca-DPA) comprises 5 to 15% of the dry weight of spores of Bacillus species. Ca-DPA is important in spore resistance to many ...
