Ammonifex degensii KC4

Ammonifex degensii (strain DSM 10501 / KC4) is an extremely thermophilic, strictly anaerobic Gram-positive bacterium isolated from a neutral volcanic hot spring. The temperature range for growth at is between 57 and 77 degrees Celsius, with optimum growth at 70 degrees Celsius. The optimum pH for growth is 7.5, and the optimum NaCl concentration for growth is 0.1%. Ammonifex degensii grows autotrophically by oxidation of hydrogen or formate, reducing nitrate to ammonium. Instead of nitrate, sulfate or sulfur are used as electron acceptors and H2S is formed as final product. Pyruvate is fermented to acetate, CO2, and hydrogen. (Adapted from PMID: 11539844).
