description
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 (C 4), esterase lipase (C 8), 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 (C 14), trypsin, α - galactosidase, β - glucuronidase, β - galactosidase, β - glucosidase, α - mannosidase and β - fucosidase. Analysis using the API 20 NE 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 A 4 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 %.
etymology
Nesterenkonia salmonea (sal. mo'ne. a. N. L. fem. adj. salmonea dark-salmon-coloured, referring to the colour of the colonies on solid medium).
