Closely related to Lysinibacillus fusiformis and Lysinibacillus sphaericus.
Description is based upon a single isolate.
Gram-positive, motile rods, 1.0 x 4.0-5.0 µm. Produce terminal, spherical
endospores in swollen sporangia; spores show an additional exosporium layer.
Colonies are smooth, flat, with entire edges, beige. Aerobic. Growth temperature
25-42 ºC (optimum 30 ºC); pH 6-10 (optimum pH 7). Grow in 0-5% NaCl. Alantoin or
urate are not required for growth.
Isolated from the surface of the Mars Odyssey spacecraft. Resistant to desiccation, H2O2 and UV and gamma radiation.
Undetermined.
