Study Notes
Spore Characteristics
- Spores can allow bacteria to exist in suspended animation for centuries
- Spores contain a high concentration of calcium bound to dipicolinic acid
- Spores protect the DNA from intense heat and radiation
- Spores do not contain high concentrations of essential proteins and ribosomes
- Spores do not contain a complete copy of the chromosomes
Spore-Forming Bacteria
- Some Gram-positive (G+) bacteria, but not Gram-negative (G-) bacteria, form spores
- Examples of spore-forming bacteria include Bacillus and Clostridium
- Other Gram-positive bacteria, such as Staphylococcus and Streptococcus, do not form spores
