Biomarkers of bacterial spore germination
WebThe germination of dormant spores of Bacillus species is the first crucial step in the return of spores to vegetative growth, and is induced by nutrients and a variety of non-nutrient agents. Nutrient germinants bind to receptors in the spore's inner membrane and this interaction triggers the releas … Spore germination Curr Opin Microbiol. WebSep 25, 2008 · Dipicolinic acid (DPA), a unique constituent of bacterial spores, exists in the spore core as a 1:1 chelate with predominantly Ca 2+ ions (Ca-DPA), which accounts for up to 15% of the total spore dry weight [9].Ca-DPA is released within the first few minutes of spore germination [10] and is therefore a prime candidate as a marker for their …
