sp. nov., isolated from seawater surrounding scleractinian coral No Access

Abstract

A Gram-stain-negative, aerobic, rod-shaped bacterium (D1M17) was isolated from the seawater surrounding scleractinian coral in Daya Bay, Shenzhen, PR China. Strain D1M17 grew with 0–10 % (w/v) NaCl (optimum, 3–4 %), at 15–37 °C (optimum, 28 °C) and at pH 4.5–8.5 (optimum, pH 7.0–7.5). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain D1M17 formed a lineage within the genus , family , and it was distinct from the most closely related species LMG 25375, JCM 17453 and KCTC 22663 with 16S rRNA gene sequence similarities of 97.2, 97.2 and 97.1 %, respectively. The major respiratory quinone was MK-6. The predominant fatty acids (more than 10 %) were iso-C (28.8 %), iso-C 3-OH (21.5 %) and iso-C G (13.1 %). The DNA G+C content of D1M17 was 34.4 mol%. The polar lipids in D1M17 comprised one phospholipid and five unknown polar lipids. Phenotypic characteristics (physiological, biochemical and chemotaxonomic) also supported the taxonomic novelty of this isolate. Thus, strain D1M17 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is D1M17 (=KCTC 92172= MCCC 1K07224).
