Description of Hongiella marincola sp. nov.

Hongiella marincola (ma.rin9co.la. L. gen. n. maris of the sea; L. n. incola inhabitant; N.L. n. marincola inhabitant of the sea).

Cells are rods, 0·4–0·6×2·0–3·0 µm on MA. Non-motile. Colonies are circular, smooth, low convex, glistening, moderately reddish-orange in colour and 1·0–2·0 mm in diameter after 3 days incubation at 37 °C on MA. Optimal growth temperature is 37 °C. Growth occurs at 10 and 45 °C, but not at 4 °C or above 46 °C. Optimal pH for growth is between 6·5 and 7·5. Growth is observed at pH 5·5, but not at pH 5·0. Optimal growth occurs in the presence of 2–3 % (w/v) NaCl. No growth occurs in the presence of> 9 % (w/v) NaCl. Growth does not occur under anaerobic conditions on MA. Tyrosine is hydrolysed weakly. Hypoxanthine, xanthine and birchwood xylan are not hydrolysed. Acid is produced from D-xylose, melibiose, L-arabinose, D-melezitose, D-glucose, D-galactose, D-mannose, D-cellobiose, lactose, sucrose, maltose, D-trehalose and D-raffinose, but not from D-sorbitol, myo -inositol, D-ribose, D-mannitol, adonitol or L-rhamnose. Acid production from D-fructose is variable (positive for type strain). Formate is not utilized. The predominant isoprenoid quinone is MK-7. The major fatty acids are iso-C15: 0, iso-C17: 0 3 -OH, iso-C16: 0 and C16: 1ω7 c and/or iso-C15: 0 2 -OH. The DNA G + C content is 43 mol% ( HPLC). Other phenotypic characteristics are given in Table 1.

The type strain, SW-2T (= KCTC 12180 T = DSM 16067 T), was isolated from sea water of the East Sea of Korea. The reference strain is SW-26 (= KCTC 12181 = DSM 16068 ) .
