Akkermansia muciniphila and obesity studyCarbon dioxide enhances Akkermansia muciniphila fitness and anti-obesity efficacy in high-fat diet mice.
We explored how the gut bacterium Akkermansia muciniphila interacts with its environment in the context of obesity. Specifically, we investigated the effects of carbon dioxide on A. muciniphila's growth and its ability to help reduce weight in mice consuming high-fat diets. The study showed that this bacterium thrives on the carbon dioxide it produces and uses enzymes to assist its development.
To enhance the delivery of A. muciniphila in the intestinal environment, we designed an innovative delivery system combining calcium carbonate, inulin, A. muciniphila, and sodium alginate. While we saw positive results with weight loss among the mice, it’s important to point out that the specific role of calcium in this weight loss remains unclear due to the complexity of the supplement used.
Furthermore, we noted significant changes in the human gut microbiota in response to carbon dioxide, with prompts for enzymes that engage in carbon dioxide-related metabolism being particularly responsive. While our findings elucidate some mechanisms of growth for gut bacteria, they also underline the challenge of isolating the specific effects of calcium on obesity from other components of the delivery system.
