Gram-positive short rods and cocci, 0.8-1.0 µm, occurring in pairs or clusters.
Non-motile. Non-spore-forming.
Non-motile. Non-spore-forming.
Colonies on NA after 48 h are less than 1 mm in diameter, light yellow, round with
entire margins, of low convexity, opaque and smooth. Optimal temperature for growth
is 22-30 ºC. Weak growth at 4 ºC and 37 ºC, and no growth at 45 ºC. Can grow on
medium with 15% NaCl. Optimum pH for growth is 7-8. Aerobic.

Description is based mostly on API Coryne and API ZYM results.
Positive results for acid and alkaline phosphatase, catalase, esterase C4, esterase lipase C8, beta-glucuronidase, gelatinase,
leucine arylamidase, nitrate reduction, pyrazinamidase, phosphoamidase (weak), and trypsin.
Negative results for cystine arylamidase, chymotrypsin, alpha-fucosidase, alpha-galactosidase, beta-glucuronidase,
N-acetyl-beta-glucosaminidase, lipase C14, valine arylamidase, fermentation of ribose, xylose, mannitol and glycogen.
Variable results for beta-galactosidase, alpha- and beta-glucosidase, alpha-mannosidase, pyrrolidonyl arylamidase, urease,
fermentation of glucose, lactose, maltose and sucrose.
