Species description is based on a single isolate.
Gram-positive rods, 0.6-0.9  x 1.8-2.5 µm. Motile. Produce central-paracentral,
ellipsoidal endospores in unswollen sporangia.
Colonies formed on TGY are creamy white, mucoid, translucent, raised and are
3-4 mm in diameter after 2 days of incubation at 37
ºC. Able to grow on NA, LB, R2A,
TSA and TGY agar.  Grows at 15-60 ºC (optimum at 37 ºC), at pH 5.5-10 (optimum pH
7) and in  0-12% (w/v) NaCl.
Isolated from soil in Evolution Canyon III in the Southern Negev desert in Israel.
Undetermined.

Positive results for caseinase, catalase, citrate utilization, gelatinase, starch hydrolysis, acid production from: glucose (without gas
production).
