L. gen. n. alvi, of the bowel, referring to the isolation source (human gut).
Nomenclatural type
Strain: CIP 112449 = JCM 31474 = Mx-05 = Mx1201

Validly published under the ICNP


The strain Mx-05 was isolated from the human gut. The cells of Mx-05T are non-motile cocci 0.4–0.7 μm in diameter. They grow anaerobically and reduced methanol, mono-, di-, and trimethylamine into methane, using H2 as an electron donor. Mx-05 grows at temperature range between 30 °C and 40 °C (optimum 37 °C), over a pH range of 6.9–8.3 (optimum pH 7.5). The genome is 1.67 Mbp with a G+C content of 55.5 mol%.
