Gram-negative, nonmotile, medium-sized rods. Occur singly and in pairs, sometimes
in short chains. Produce subterminal / paracentral, ellipsoidal endospores in swollen
sporangia.
Colonies are 1-2 mm in diameter, beige or cream, shiny, with slightly translucent
edges on TSA. Aerobic. Growth temperature 30-50 ºC (optimum 37 ºC); pH 7. Grow in
0-7% NaCl. Alantoin or urate are not required for growth.
Isolated from the hindgut of termite Reticulitermes santonensis Feytaud, and from raw milk and cattle feed concentrate.  No growth in
the presence of lysozyme (0.001%).
Undetermined.
