Akkermansia muciniphila is a species of human intestinal mucin-degrading bacterium. It is Gram-negative, strictly anaerobic, non-motile, non-spore-forming and oval-shaped. Its type strain is MucT (=ATCC BAA-835T =CIP 107961T).[1] Extensive research is being undertaken to understand its association with obesity and diabetes.[2][3][4]
Description of Akkermansia muciniphila sp. nov.
Akkermansia muciniphila (mu.ci.ni'phi.la. N.L. neut. n. mucinum mucin; Gr. adj. philos loving; N.L. fem. adj. muciniphila mucin-loving).
Cells are oval-shaped, non-motile and stain Gram-negative. The long axis of single cells is 0.6–1.0 mm, depending on the substrate used. Cells occur singly, in pairs, in short chains and in aggregates. Growth occurs at 20–40°C and pH 5.5–8.0, with optimum growth at 37°C and pH 6.5. Strictly anaerobic. Able to grow on gastric mucin, brain–heart infusion and Columbia media, and on N-acetylglucosamine, N-acetylgalactosamine and glucose when these three sugars are in the presence of (each at 2 g l-1) peptone, yeast extract, casitone and tryptone. Cellobiose, lactose, galactose, xylose, fucose, rhamnose, maltose, succinate, acetate, fumarate, butyrate, lactate, casitone, Casamino acids, tryptone, peptone, yeast extract, proline, glycine, aspartate, serine, threonine and glutamate do not support growth. Capable of using mucin as carbon, energy and nitrogen source. Able to release sulfate in a free form from mucin fermentation. In mucin medium, cells are covered with filaments. Growth occurs without vitamins. Colonies appear white with a diameter of 0.7 mm in soft agar mucin medium.
The type strain is MucT (=ATCC BAA-835T=CIP 107961T), isolated from the human intestinal tract. Its DNA G+C content is 47.6 mol%.[1]: 1474
