Gram-positive cocci, 0.7-0.8 µm in diameter. Non-motile. Non-spore-forming.
Colonies on MA are 1mm in diameter, opaque, smooth, circular with regular margins,
convex and light-yellow in colour after 6 days at 30 °C. Growth occurs in 0-9% (w/v)
NaCl (optimum 1-4%), at pH 7-12 (pH 9-10) and at 10-40 °C (30-35 °C). Aerobic.

Description is based mostly on API 20 NE and API ZYM results.
Positive results for acid and alkaline phosphatase, catalase, cystine arylamidase (weak), esterase (C4), esterase lipase (C8),
esculin hydrolysis, gelatin hydrolysis, leucine arylamidase, alpha-chymotrypsin, naphthol-AS-BI-phosphohydrolase, oxidase, and
valine arylamidase (weak).
Negative results for arginine dihydrolase, casein hydrolysis, cellulose hydrolysis, alpha- and beta-galactosidase, beta-glucuronidase,
alpha- and beta-glucosidase, N-acetyl-beta-glucosaminidase, H2S production, indole production, lipase (C14), methyl red test,
melanin production, alpha-mannosidase, nitrate reduction, starch hydrolysis, trypsin, Voges-Proskauer reaction, and glucose
fermentation.
No utilization of arabinose, adipate, caprate, citrate, glucose, gluconate, malate, maltose, mannose, mannitol, N-acetylglucosamine,
and phenylacetate.
