Gram-positive, bent rods. Nonmotile.
Colonies are circular, convex and form yellowish-white-pigmented. Good growth is
observed on ISP2 medium, AIA, SA and nutrient agar after 7 days at 28 ºC; moderate
growth on SCA, and poor growth on ISP7 medium. Can grow in 0-4% (w/v) NaCl,
24-40 ºC, pH 5.0-8.0; optimal growth occurs at 0-2% NaCl, 28-36 ºC and pH 6-7.
Strictly aerobic. Non-haemolytic.
Isolated from mangrove soil of the Tanjung Lumpur forest in Pahang, Malaysia. Susceptible to D-serine, potassium tellurite,
ampicillin, ampicillin sulbactam, cefotaxime, cefuroxime, cephalosporin, chloramphenicol, ciprofloxacin, erythromycin, gentamicin,
penicillin G, streptomycin, tetracycline and vancomycin. Resistant to nalidixic acid, lithium chloride.
Undetermined.
