Study Notes

Spores

Spores allow bacteria to exist in suspended animation for centuries.
Spores contain a high concentration of calcium bound to dipicolinic acid.
Spores contain a complete copy of the chromosomes, but do not contain high concentrations of essential proteins and ribosomes.
Spores protect DNA from intense heat, radiation, and other environmental stresses.

Bacteria that Form Spores

Only some Gram-positive (G+) bacteria, such as Bacillus and Clostridium, are capable of forming spores.
Gram-negative (G-) bacteria do not form spores.

Antibiotic Resistance

The misuse of antibiotics, including their use in animal feed, selects for resistance mutants, contributing to the development of antibiotic-resistant bacteria.
