description
Following incubation for 3 days at 37 ° C on modified MA, the slender rod-shaped cells (~ 0.2 – 0.3 µm × 0.7 – 3.2 µm) are Gram-stain-positive, motile and non-spore-forming. Colonies are entire, convex, slimy, clear, yellowish in colour and approximately 1.0 mm in diameter. Good growth on modified MA and TSA, moderate growth on ISP 2 agar, and weak growth on LB and ISP 4 agar plates. Growth is observed at 10 – 45 ° C, pH 5.0 – 10.0 and in the presence of 0 – 11 % (w / v) NaCl. Optimum growth occurs at 37 ° C, pH 6.0 and 0 – 1 % (w / v) NaCl. The activities of cellulase, amylase, xylanase and proteinase are negative. Positive for esterase (C 4), esterase lipase (C 8), leucine arylamidase, valine arylamidase, cystine arylamidase, naphthol-AS-BI-phosphohydrolase and β - glucosidase. Negative for alkaline phosphatase, lipase (C 14), trypsin, α - chymotrypsin, acid phosphatase, α - galactosidase, β - galactosidase, β - glucuronidase, α - glucosidase, N - acetylβ - glucosaminidase, α - mannosidase and β - fucosidase. Analysis using the API 20 N system returns positive results for the Voges – Proskauer reaction, arabinose fermentation and gelatinase production, but negative results for citrate utilization, glucose fermentation, the production of H 2 S and indole, and catabolism of mannitol, inositol, sorbitol, sucrose, rhamnose, melibiose and amygdalin. The major cellular fatty acids are anteiso-C, anteiso-C A, iso-C 16: 0 and anteiso-C 17: 0. The total polar lipids are phosphatidylglycerol, diphosphatidylglycerol and three unknown glycolipids. The predominant menaquinones are MK- 11 (8 %), MK- 12 (48 %), MK- 13 (31 %) and MK- 14 (13 %). The cell-wall peptidoglycan contains lysine as a diamino acid. The DNA G + C content is 69.6 mol % and the genome size is 2.59 Mb. 15: 0 15: 0 The type strain, CTD 02 - 10 - 2 T (= JCM 33842 T = MCCC 1 A 16619 T), was isolated from a deep sea water sample collected from the Indian Ocean. The NCBI GenBank accession numbers for the 16 S rRNA gene sequence and the complete genome sequence of strain CTD 02 - 10 - 2 T are MN 463006 and CP 058670, respectively.
