Gram-variable, rods, 0.7 x 1.5 μm. Motile by peritrichous flagella. Produce ellipsoidal
spores positioned terminally / subterminally in swollen sporangia.
Colonies are slightly convex, cream, nonpigmented, brigt on Triptic Soy Agar. Aerobic,
facultatively anaerobic. Psychrotolerant; growth temperature 4 to 31 ºC, optimum
10-15 ºC. Grow at 4.5-9.0 pH (optimum 7.0) and in 2% and 4% NaCl, but not in 5%
NaCl media.
Isolated from sediment collected in Chlorite Lake on the Byers Peninsula of Livingston Island , South Shetland Islands, Antarctic.
Resistant to lysozyme 0.001%.
Undetermined.
