sp. nov., isolated from coral No Access

Abstract

A non-motile, rod-shaped, pink-pigmented bacterium NAR14 was isolated from coral from Daya Bay, Shenzhen, PR China. Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-negative. NAR14 grew with 0–6 % (w/v) NaCl (optimum, 2–4 %), at 10–41 °C (optimum, 28 °C) and at pH 4.0–9.5 (optimum, 5.0). The major respiratory quinone was Q-10. The predominant fatty acids (more than 10%) were summed feature 8 (65.6 %) and C (17.6%). The DNA G+C content of NAR14 was 73.6 %. The polar lipids of NAR14 comprised one diphosphatidylglycerol, one phosphatidylethanolamine, one phosphatidylglycerol, one phosphatidylcholine, one aminolipid and three unknown polar lipids. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that NAR14 formed a lineage within the genus of the family , and it was distinct from the most closely related species JCM 19527 and JCM 17520 with the 16S rRNA gene sequence similarities of 94.61 and 93.98 %, respectively. Phenotypic characteristics (physiological, biochemical and chemotaxonomic) also supported the taxonomic novelty of this isolate. Thus, NAR14 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is NAR14 (=KCTC 92174 = MCCC 1K07275).
