- Researchers study microbes that live in sourdough starters.
- They want to know how species live together.
- The team measured growth alone and in pairs.
- They used those measures to build a simple model.
- The model often predicted which species would coexist.
- Only a few species behaved differently than predicted.
- Researchers adjusted the model to match starter cycles.
- This work helps baking, food safety, and health.
- Sourdough cycles include feeding, using, and renewing starter.
- Similar ideas may apply to other microbial systems.
