ramosus Jensen 1960.
Motile by a few lateral flagella.
Colonies on yeast extract peptone media show no distinctive pigmentation.
Nutritionally nonexacting: growth occurs in a suitable mineral salts medium with an
ammonium salt or nitrate as sole nitrogen source. Tolerates 3% NaCl. Can grow on
MacConkey agar.
Isolated from beech forest soil samples at depth of 30-35 cm. One strain was isolated from mercuric salt-contaminated soil.
Resists and accumulates several metals, such as cadmium, cobalt, zinc, chromium and mercury.
Undetermined.
