The lots of of species of microorganisms that comprise the microbiome all have completely different, distinctive roles.
One of many vital capabilities that takes place within the intestine is the manufacturing of short-chain fatty acids. These molecules are derived from the fermentation of polysaccharides (a sort of carbohydrate) that are primarily present in starchy meals. These short-chain fatty acids are then utilized in a spread of processes – together with offering cells with the vitality they should develop and multiply and enabling communication between the intestine and the mind.
The intestine’s microbes primarily make three short-chain fatty acids: acetate, propionate and butyrate. Collectively, these present round 60% of all vitality utilized by the intestinal cells – and about 10% of our physique’s general calorie necessities.
Arguably, a very powerful of those short-chain fatty acids is butyrate, which has been extensively studied attributable to its obvious hyperlinks to well being and illness.
Butyrate is the first supply of vitality used to create and preserve the mucus membrane that strains our digestive tract. This lining is important for wholesome intestine perform, defending the physique from an infection and absorbing vitamins from the meals we eat.
One of many major producers of butyrate within the intestine is the bacterium Roseburia intestinalis.

R intestinalis lives in shut contact with the mucus membrane of our intestine cells and makes up simply over 2% of all the inhabitants of the human intestine microbiome. It creates butyrate from the polysaccharides we eat utilizing a particular sort of enzyme. Whereas it isn’t the one bacterium within the intestine that produces butyrate, R intestinalis is one among its most considerable producers.
R intestinalis has been linked to many well being advantages, reminiscent of stopping irritation and restoring good bacterial stability within the microbiome.
This bacterium additionally appears to manage a few of the communication that occurs between the intestine and mind – and will even play a job in defending towards some illnesses, reminiscent of Crohn’s, ulcerative colitis and each sort 1 and kind 2 diabetes.

These well being advantages are in all probability due to the truth that the butyrate R intestinalis produces gives vitamins and vitality to different bacterial species who’ve extra specialised jobs within the intestine. Butyrate additionally helps regulate many facets of our immune system. It does this by way of selling or suppressing the manufacturing of key immune cells.
A lot of those discoveries of R intestinalis’s advantages are very latest and extra analysis might be wanted to higher verify what particular roles this bacterium performs within the intestine, and the way precisely it enhances our personal struggle towards illness.
Butyrate manufacturing may additionally be extra complicated than it seems, with research discovering a hyperlink between low ranges of butyrate manufacturing and weight problems.
However given its key position in selling a wholesome intestine – alongside its wider results on the immune system and physique – it’s no marvel R intestinalis is beginning to be thought-about as a possible probiotic. This might imply we might see it added to dietary supplements with a purpose to promote a more healthy microbiome sooner or later.
This text is a part of Meet Your Intestine Microbes, a collection concerning the wealthy constellation of micro organism, viruses, archaea and fungi that reside in folks’s digestive tracts. Scientists are more and more realising their significance in shaping our well being – each bodily and psychological. Every week we are going to take a look at a unique microbe and produce you essentially the most up-to-date analysis on them.
