Gram-positive cells. Nonmotile. Spore not formed. Shows a rod–coccus growth cycle.
Colonies are round, convex, glossy, with entire margins and are light yellow. Growth
occurs on nutrient broth agar at 5-40 ºC, optimal temperature for growth is 30 ºC.
Grows in the presence of 3-7% (w/v) NaCl. The pH range for growth is 6-11 (optimum
pH is 8.5).

Isolated from a filtration substrate made from volcanic rock from Niigata, Japan.
