Description
Bacterial spores can sleep through heat and chemicals that would kill growing cells, then wake and spoil food. Nana Asiamah Boateng and co-authors watch that waking moment in the food-relevant species Bacillus subtilis. They trigger germination two ways, with a rich broth and with a defined mix of nutrients, and sample the liquid every hour.
A strong magnetic resonance instrument read the small molecules the spores released. Both triggers produced a shared signature set, led by dipicolinic acid, a spore-only chemical, and the amino acid alanine. A handful of small acids appeared in both runs as well. Because the same markers show up regardless of trigger, the authors propose them as reliable alarms for spore germination in food safety testing.
