Cells are non-motile, regular cocci. Growth is observed between 55 and 85 degrees Celsius, with an optimum at 65-70 degrees Celsius (doubling time, 6.1 h), and at pH 4.5-7.5, with optimum growth at pH 5.56.0. No growth is observed at 53 or 89 degrees Celsius or at pH 4.0 or 8.0. F.fontis is organotrophs and grows on a narrow spectrum of energy-rich substrates, such as beef extract, gelatin, peptone, pyruvate, sucrose and yeast extract. Weaker growth is observed on albumin, amygdalin, arabinose, cellobiose, pyruvate, rhamnose, soy flour, sucrose and tryptone . Sulfate, sulfite, thiosulfate and nitrate added as potential electron acceptors did not stimulate growth when tested with peptone. (Adapted from PMID: 19837732)."xsd:string |
