sp. nov., isolated from the surface of a marine red alga.

A Gram-stain-negative, non-flagellated bacterium, designated ZY111, was isolated from the surface of a marine red alga, which was collected from the coast in Weihai, Shandong Province, PR China. Strain ZY111 exhibited growth at 4-37 °C (optimum, 25-28 °C) in the presence of 0-8.0 % (w/v) NaCl (optimum, 2.0-4.0% NaCl) and at pH 6.5-9.5 (optimum, pH 7.0-8.0). The 16S rRNA gene sequence analysis revealed that strain ZY111 belonged to the genus , with DSM 29199 as its closest relative (97.7 % similarity). The averagenucleotide identity value of strain ZY111 with DSM 29199 was 79.03 %. The digitalDNA-DNA hybridization value of strain ZY111 with DSM 29199 was 22.40 %. The dominant fatty acids were iso-C, iso-C G, iso-C 3-OH and iso-C 3-OH. The sole respiratory quinone was determined to be menaquinone-6. The polar lipid profile of strain ZY111 consisted of phosphatidylethanolamine, two unidentified aminolipids and three unidentified lipids. The G+C content was 31.9 mol%. The phenotypic, chemotaxonomic and phylogenetic data clearly showed that strain ZY111 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ZY111 (=KCTC 62373=MCCC 1H00295).
