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

-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

), was isolated from marine sediment collected from the
Southern Atlantic Ocean
.
