Species description is based on a single isolate.
Gram-positive bent rods, 0.5-0.9 x 1.7-4.5 um. Non-motile.
Colonies are circular, convex and pale yellow in colour after 24 h cultivation at 30-37
ºC on TYB, YDC or PYES agar. Growth occurs at 15-42 ºC (optimum 30-37 ºC) and
pH 5.0-9.0 (optimum pH 6.0-8.0).  Growth occurs with 0-3 % (w/v) NaCl, but not with
4% (w/v) NaCl. Aerobic.
Isolated from  the surface of weathered biotite in Susong, Anhui Province, China.
Undetermined.
