Bacteria found in the guts of serious athletes help mice exercise longer by transforming their metabolic waste!
Microbe of the episode
Microbe of the episode: Aggregatibacter (Actinobacillus) actinomycetemcomitans
This study found that certain such bacteria, when given to mice, enabled the mice to run for a longer period on a treadmill. These microbes break down lactic acid, which is generated in our bodies when we push our physical limits, but the study provided evidence that the longer run times were due not to removal of this waste product, but to the propionate compound produced by its degradation.
