Lactic Acid reducing bug found in microbiome of athletes

Broad spectrum antibiotics can wipe out a lot of good bacteria in our guts.

"This bug's natural function is to break down lactic acid," Scheiman says.

"We are more bacteria than we are human," says Scheiman, who is a postdoctoral fellow in the laboratory of George Church, Ph.D., at Harvard Medical School. "The bugs in our gut affect our energy metabolism, making it easier to break down carbohydrates, protein and fiber. They are also involved in inflammation and neurological function. So perhaps the microbiome could be relevant for applications in endurance, recovery and maybe even mental toughness."...

As a first step toward identifying bacteria that support athletic performance, the researchers collected fecal samples on a daily basis from 20 athletes training for the 2015 Boston marathon, one week before and one week after the race...

The researchers sequenced the genomes of the sampled bacteria, using computational metagenomic methods to figure out how many and what types of microbes inhabited the fecal samples.

When they compared the pre-race and post-race samples, the researchers found a sudden spike in the population of one particular type of bacteria after the marathon. "This bug's natural function is to break down lactic acid," Scheiman says. During intense exercise, the body produces more lactic acid than usual, which can lead to muscle fatigue and soreness. This bacteria could potentially help with that.

The team has isolated the bacteria from fecal samples and is beginning to evaluate its properties. They've already determined that the bug excels at breaking down lactic acid in a test tube and remains viable after it passes through the digestive system of mice. The researchers are now feeding the bacteria to mice to measure its effects on lactic acid levels and fatigue...

The researchers are presenting their work today at the 254th National Meeting & Exposition of the American Chemical Society (ACS)...

Thank you chocolove!
Prevotella bacteria producing Thiamine help a lot to handle with blood lactates, maybe they found others genus involved! I'm thrilled to read the work of these scientists!

Wow, I'd like some of those bacteria....
