Colonies of the S. oahuensis strain A5586T are dark yellow (Butterscotch, Hex code #FABD02), circular shape, butyrous consistency, smooth surface, flat relief with undulate margins, and 0.4–0.7 mm (average 0.55) in diameter on YDC medium plates after incubation at 28°C for 2 days. Cells are gram-negative and able to utilize dextrin, D-maltose, D-trehalose, D-cellobiose, gentiobiose, Β-methyl-D-glucoside, D-salicin, N-acetyl-D-glucosamine, α-D-glucose, D-mannose, 1% sodium lactate, gelatin, glycyl-L-proline, lincomycin, guanidine HCl, vancomycin, tetrazolium violet, tetrazolium blue, citric acid, α-ketoglutaric acid, L-malic acid, bromo-succinic acid, lithium chloride, propionic acid, acetic acid, and aztreonam. Cells grow under the conditions of pH 6, 1% NaCl, or 4% NaCl but cells survive neither pH 5 nor 8% NaCl solution. In contrast, cells are unable to oxidize sucrose, stachyose, D-raffinose, N-acetyl-β-D-mannosamine, N-acetyl-neuraminic acid, D-galactose, 3-methyl-glucose, inosine, D-fucose, L-fucose, L-rhamnose, inosine, fusidic acid, D-sorbitol, D-mannitol, D-arabitol, myo-inositol, glycerol, D-glucose-6-PO4, D-aspartic acid, D-serine, rifamycin SV, minocycline, L-arginine, L-aspartic acid, L- glutamic acid, L-histidine, L-pyroglutamic acid, L-serine, pectin, D-galacturonic acid, D-gluconic acid, D-glucuronic acid, mucic acid, quinic acid, D-saccharic acid, p-hydroxy-phenylacetic acid, D-lactic acid methyl ester, L-lactic acid, D-malic acid, nalidixic acid, potassium tellurite, γ-amino-butryric acid, α-hydroxy-butyric acid, β-hydroxy-D, L-butyric acid, α-keto-butyric acid, acetoacetic acid, formic acid, and sodium bromate. Some utilization of carbon resources and chemical components, such as D-turanose and sodium butyrate, showed faded positive results after growing A5586T cell suspension in GEN III Microplate (Biolog Inc., Hayward, CA, USA) at 28°C for 24 h. S. oahuensis sp. nov. was sensitive to seven tested antibiotics, namely, bacitracin (50 mg/mL), chloramphenicol (50 mg/mL), gentamicin (50 mg/mL), kanamycin (50 mg/mL), penicillin (50 mg/mL), tetracycline (40 mg/mL), and polymyxin B sulfate (50 mg/mL). The genome size of type strain A5586T is 4.68 Mbp, which includes a chromosome (4.62 Mbp) and a plasmid (60.78 Kbp). The DNA G + C content of the type strain is 65.3 mol%

The type strain A5586T = D-31T = ICMP 25024T = LMG 33201T was isolated from Anthurium (Araceae family) in 1981 in Hawaii, USA.
