DESCRIPTION OF NESTERENKONIA SALMONEA SP. NOV.

Nesterenkonia salmonea (sal.mo'ne.a. N.L. fem. adj. salmonea dark-salmon-coloured, referring to the colour of the colonies on solid medium).

Cells are Gram-stain-positive, aerobic, non-motile and rod-shaped, approximately 0.4–0.5 µm in diameter and 0.7–1.0 µm long. Colonies on MA are approximately 1 mm in diameter, opaque, smooth, circular with regular margins, convex and dark salmon in colour after 6 days at 30 °C. Growth occurs in 0–10% (w/v) NaCl (optimum, 1–4%), at pH 7–12 (pH 9–10) and at 4–40 °C (30–35 °C). Catalase-positive and oxidase-negative. Negative for nitrate reduction, methyl red test, production of H 2 S and melanin, Voges–Proskauer reaction, and hydrolysis of starch, cellulose and casein. Assays using the API ZYM system are positive for alkaline phosphatase, esterase (C4), esterase lipase (C8), leucine arylamidase, α -chymotrypsin and naphthol-AS-BIphosphohydrolase; weakly positive for valine arylamidase, cystine arylamidase and acid phosphatase; negative for N -acetyl- β -glucosaminidase, α -glucosidase, lipase (C14), trypsin, α -galactosidase, β -glucuronidase, β -galactosidase, β -glucosidase, α -mannosidase and β -fucosidase. Analysis using the API 20NE system reveals that cells are positive for hydrolysis of aesculin and gelatin; negative for the remaining 18 substrates. The major menaquinones are MK-7, MK-8 and MK-9. The peptidoglycan type is A4 α, L-Lys-Gly–L-Glu. The polar lipids detected are diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, one unidentified glycolipid, one unidentified lipid and one unidentified phospholipid. The major fatty acids are anteiso-C 17:0, anteiso-C 15:0 and anteiso-C 17:1; in addition, significant amounts of iso-C 15:0, iso- C 16:0 and iso-C 17:0 are also present. The genomic DNA G+C content of the type strain is 61.1 mol%.

The type strain, GY074 T = (KCTC 39639 T =MCCC 1A11256 T), was isolated from marine sediment collected from the Southern Atlantic Ocean .
