description
Cells are strictly aerobic, Gram-stain-negative, nonmotile, rod-shaped, approximately 2.3 – 3.9 µm long and 1.0 – 1.2 µm in diameter. Colonies on R 2 A agar are circular, smooth, pale-pink coloured and approximately 1.0 mm in diameter after 3 days at 30 ° C. Growth occurs at 10 – 30 ° C (optimum, 30 ° C), at pH 6 – 8 (optimum, pH 7) and in the presence of 0 – 0.5 % NaCl (optimum, 0 %). Catalase and oxidase activities are positive. Flexirubin-type pigments are not produced. Growth does not occur on nutrient, marine, tryptic soy and blood agars. Dextrin is hydrolysed, but CM-cellulose, DNA, starch, casein (skimmed milk) or cellulose (filter paper) are not. In the API 20 NE strip, positive for aesculin hydrolysis and β - galactosidase (PNPG test) activities, and the assimilation of D-glucose, D-mannitol, maltose, potassium gluconate, adipic acid and malic acid; negative for arginine dihydrolase, urease, nitrate reduction, indole production, glucose fermentation and gelatinase activities, and the assimilation of L-arabinose, D-mannose, N - acetylglucosamine, capric acid, trisodium citrate and phenylacetic acid. In the API ZYM strip, alkaline phosphatase, esterase lipase (C 8), leucine arylamidase, valine arylamidase, cystine arylamidase, trypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase, β - galactosidase, α - glucosidase, β - glucosidase and N - acetylβ - glucosaminidase are present; esterase (C 4), lipase (C 14), α - chymotrypsin, α - galactosidase, β - glucuronidase, α - mannosidase and α - fucosidase activities are absent. In the API 50 CH strip, positive for acid production from aesculin ferric citrate; but negative for acid production from glycerol, erythritol, D-arabinose, L-arabinose, D-ribose, D-xylose, L-xylose, D-adonitol, methyl β - Dxylopyranoside, D-galactose, D-glucose, D-fructose, D-mannose, L-sorbose, L-rhamnose, dulcitol, inositol, D-mannitol, D-sorbitol, methyl α - D-mannopyranoside, methyl α - D-glucopyranoside, N - acetyl-glucosamine, amygdalin, arbutin, salicin, cellobiose, maltose, lactose, melibiose, sucrose, trehalose, inulin, melezitose, raffinose, starch, glycogen, xylitol, gentibiose, turanose, D-lyxose, D-tagatose, D-fucose, L-fucose, D-arabitol, L-arabitol, potassium gluconate, potassium 2 - keto-gluconate and potassium 2 - keto-gluconate. The major cellular fatty acids (> 10 %) are summed feature 3 (C ω 7 c and / or C 16: 1 ω 6 c), iso-C and C 16: 1 ω 5 c. The only respiratory quinone is MK- 7. The polar lipids contain phosphatidylethanolamine, one unidentified aminoglycolipid, three unidentified aminophospholipids, one unidentified phospholipid, three unidentified aminolipids, two unidentified glycolipids and three unidentified polar lipids. The genomic DNA G + C content of strain HMF 4947 T is 59.3 mol %. * Data from: a, Chung et al. [5]; b, Ten et al. [6]; c, Kang et al. [15]; d, Hoang et al. [33]. 16: 1 15: 0 The type strain is HMF 4947 T (= KCTC 72780 T = NBRC 114271 T), isolated from a ginkgo tree of the Yongin, Republic of Korea. The GenBank accession number for the 16 S rRNA gene sequence of strain HMF 4947 T is MN 595016. The whole genome accession number of strain HMF 4947 T is WQKZ 00000000.
