description
Cells are Gram-stain-negative, aerobic, non-motile, and rod-shaped (0.4 – 0.6 × 0.7 – 2.1 µm). Colonies are circular, convex with clear margin and yellow-coloured after 4 days on R 2 A agar. Growth was observed on trypticase soy agar, R 2 A agar and Luria – Bertani agar, but not MacConkey agar. Growth on R 2 A agar occurs at 12 – 37 Ǫ C, pH 4.5 – 6.5 and in the presence of 0 – 1.0 % (w / v) NaCl. Optimum growth occurs at 28 Ǫ C, pH 6.0 and without NaCl supplement. Catalase-positive and oxidase-positive. Nitrate is not reduced to nitrite. Casein is hydrolysed, but gelatin, starch and Tween 80 are not. H 2 S and indole are not produced. The following substrates can be used as sole carbon sources for growth: capric acid, D- arabinose, D- galactose, D- glucose, D- mannose, maltose, sucrose, trehalose, turanose, D- lyxose, D- fucose, glycogen, inulin, N - acetyl-D- glucosamine and xylitol. The following substrates are not utilized for growth: aesculin ferric citrate, amygdalin, arbutin, capric acid, D- adonitol, D- arabitol, cellobiose, D- fructose, D- fucose, D- gentiobiose, lactose, D- lyxose, D- mannitol, melezitose, melibiose, raffinose, D- ribose, D- sorbitol, D- tagatose, dulcitol, erythritol, glycerol, inositol, L- arabinose, L- arabitol, L- rhamnose, L- sorbose, L- xylose, malic acid, methyl Oi - D- glucopyranoside, methyl Oi - D- mannopyranoside, methyl β - D- xylopyranoside, phenylacetic acid, potassium 2 - ketogluconate, potassium 5 - ketogluconate, potassium gluconate, salicin and starch ortrisodium citrate. The following enzyme activities are positive: alkaline phosphatase, acidphosphatase, arginine dihydrolase, Oi - galactosidase, Oi - glucosidase, Oi - mannosidase, Oi - fucosidase, β - galactosidase, β - glucosidase, cystine arylamidase, esterase (C 8), leucine arylamidase, N - acetyl- β - glucosaminidase and valine arylamidase. Esterase (C 4) is weakly positive. The following enzyme activities are negative: a - chymotrypsin, lipase (C 14), naphthol-AS-BI-phosphohydrolase and trypsin. Ubiquinone- 8 is the respiratory quinone, and iso-C 15: 0, iso-C 16: 0, iso-C 17: 1 Ɯ 9 c are the major cellular fatty acids (> 10 %). The G + C content of the genomic DNA is 61.7 mol %. The major polar lipids consist of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified aminophospholipid, two unidentified aminolipid and one unidentified phospholipid. The type strain, 4 M-K 27 T (= GDMCC 1.1189 T = LMG 30267 T), was isolated from forest soil sampled at Dinghushan Biosphere Reserve, Guangdong Province, PR China. The 16 S rRNA gene sequence and whole genome sequence of strain DHOA 06 T have been deposited in DDBJ / EMBL / GenBank under accession numbers KY 433857 and RYYV 00000000, respectively.
