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.

Description is based mostly on API Coryne, API 20 NE, API 50 CHB, and API ZYM (bioMerieux) results.

Positive results for arginine dihydrolase, acid phosphatase,amylase, catalase, leucine arylamidase,
naphthol-AS-BI-phosphohydrolase, beta-galactosidase, alpha- and beta-glucosidase, nitrate reduction, esterase (C4), esterase
lipase (C8), lipase (C14), cysteine arylamidase, alpha-galactosidase, N-acetyl-beta-glucosaminidase, alpha-mannosidase, and
valine arylamidase.
Can utilize as sole carbon source: cellobiose, sucrose, stachyose, alpha-D-glucose, D-fucose, D-fructose 6-phosphate, D-aspartic
acid and alpha-ketoglutaric acid.
Acid production from (API 50CH): esculin, D-fructose, D-glucose (negative in API 20 NE), glycerol, D-mannitol, D-mannose, and
D-turanose.

Negative results for  alkaline phosphatase, cellulase, chitinase, xylanase, protease, lipase, beta-fucosidase, beta-glucuronidase,
indole production,  trypsin, alpha-chymotrypsin, and urease.
Not utilized as sole carbon sources: D-salicin, D-mannitol, D-glucose 6-phosphate, gelatin, pectin, D-galacturonic acid, mucic acid,
L-lactic acid, bromosuccinic acid, beta-hydroxy-DL-butyric acid, acetoacetic acid, propionic acid, and L-alanine.
Acid is not produced from: D- and L-arabinose, D- and L-arabitol, amygdalin, D-adonitol, arbutin, D-cellobiose, dulctiol, erytritol, D-
and L-fucose, D-galactose, glycogen, gentiobiose, inulin, methyl alpha-D-mannopyranoside, N-acetylglucosamine, L-methyl
alpha-D-glucopyranoside, gluconate, 2- or 5-ketogluconate, inositol, D-lactose, D-lyxose, D-maltose, D-melibiose, D-melezitose,  
D-raffinose, D-ribose, L-rhamnose, salicin, D-sorbitol, sorbose, starch, D-sucrose, trehalose, D-tagatose, xylitol, methyl
