Kojima et al., 2022 (modified): In addition to properties listed in the genus description, cells are rod-shaped, 0.8–2.0 μm long and 0.4–0.5 μm wide. Uses oxygen and nitrate as electron acceptor. Under nitrate-reducing conditions, grows chemolithoautotrophically on thiosulfate and elemental sulfur, but not on sulfide, tetrathionate, or hydrogen gas. Grows heterotrophically on pyruvate, lactate, acetate, propionate, succinate, fumarate, malate, and butyrate. Does not grow on benzoate, isobutyrate, methanol, ethanol, formate, citrate, glucose, xylose, phenol,
o-cresol, and
m-cresol. Temperature range for growth is 28–55 °C, with an optimum of 45–50 °C. Growth occurs at pH 5.8–8.7, with an optimum of pH 6.7–7.4. G + C content of genomic DNA of the reference strain is 62.4 mol%.
The reference strain J5B(T) (= BCRC 81386(T) = DSM 104688(T) = NBRC 112605(T)) was isolated from a microbial mat of a hot spring in Japan. The GenBank/EMBL/DDBJ accession numbers for the chromosome and two plasmids of reference strain are AP018718 and AP018719-AP018720, respectively.
