Valverde, Peix, Rivas, Velazquez, Salazar, Santa-Regina, Rodriguez-Barrueco & Igual, 2008.
Description is based on a single isolate.
Gram-variable rods. Motile by polar and subpolar flagella. Produce subterminal,
ellipsoidal spores in swollen sporangia.
Colonies on nutrient agar are yellow, smooth and convex, 1-3 mm in diameter.
Grow aerobically, but not anaerobically. Grow in 2% NaCl, but not in 5% NaCl media.
Optimum growth temperature 30 ºC, but not at 40 ºC. Can grow at pH 5.7, optimum 7.
Isolated from the phyllosphere of chestnut trees growing in the Sierra de Francia region, Salamanca province, Spain.
