<unk>  was specified as being a fiber-degrading microbial specialist in the microbiomes of Western individuals. In a study geared at determining the fermentation of pectin in B.<unk>  from a rabbit cecum, it was determined that cultures grown with pectin produced more acetate than formate, lactate, fumarate, and succinate as opposed to those cultures grown on glucose which yielded vast amounts of lactate. This elucidates the metabolism of a plant fiber by a human commensal. In addition, B.<unk>  showed no growth on arabinan (a pectin), arabinoxylan (wheat), xylan, xyloglucan, glucomannan, galactomannan, B-glucan, lichenin, and laminarin. They do grow on host-derived glycans like neutral mucin O-glycans, chondroitin sulfate, and hyaluronic acid. The monosaccharides that induce growth are arabinose, fructose, fucose, galactose, galacturonic acid, glucose, glucuronic acid, glucosamine, mannose, N-acetylgalactosamine, N-acetylglucosamine, N-acetylneuraminic acid, rhamnose, ribose, and xylose
