Spore Wars
How Sporty rides out the stomach acid
- Suit up.When times get tough, B. coagulans packs its DNA into a spore: a dry, tough, seed-like coat.
- Acid rain.Your stomach runs at roughly pH 1.5 to 3.5, sour enough to fizzle most bacteria. The spore coat shrugs it off.
- Hatch!In the calmer small intestine, the spore germinates and Sporty gets back to making lactic acid.
Far-out fact
A spore is a survival suit: a tough, dry coat that lets B. coagulans ride out stomach acid and wake up further down.
