sp. nov., isolated from Yongle Blue Hole in the South China Sea No Access

Abstract

A Gram-stain-negative, non-motile, facultatively anaerobic and non-flagellated marine bacterium, designated JC070 was isolated from the Yongle Blue Hole in the South China Sea. The temperature, pH and NaCl ranges for growth of strain JC070 were 4–37 °C (optimum, 16 °C), pH 6.0–9.0 (optimum, pH 7.0) and 1.0 –6.0% (w/v; optimum, 3.0%). The predominant isoprenoid quinone of strain JC070 was identified as menaquinone-7. The dominant fatty acids (>10%) were iso-C (59.6%) and iso-C 3-OH (17.2%). The major polar lipids were aminophospholipid, aminolipid, two unknown phospholipids and two unidentified lipids. The genomic DNA G+C content was determined to be 37.0 mol%. Based on the results of polyphasic analysis, a new species, named sp. nov., within the genus was proposed. The type strain is JC070 (= JCM 39045=MCCC 1K03774).
