sp. nov., isolated from intertidal seawater in Taizhou.

A Gram-stain-negative, aerobic, chemoheterotrophic and rod-shaped strain, designated as C5, was isolated from intertidal surface seawater in Taizhou, Zhejiang Province, PR China and characterized using a polyphasic taxonomic approach. Strain C5 could produce carotenoids and bacteriochlorophyll . Growth was observed at 20-45 °C, at pH 6.0-9.0 and with 0-8.0 % (w/v) NaCl. The 16S rRNA gene sequence identity analysis revealed that strain C5 was the most closely related to CGMCC 1.7715 (98.8%) and DSM 8509 (98.7%). The phylogenetic reconstruction based on core genes demonstrated that strain C5 was clustered into the members of the genus . The average nucleotide identity and digital DNA-DNA hybridization values between strain C5 and type strains were lower than 76 and 25 %, respectively. The predominant and minor respiratory quinones were identified as ubiquinone-10 and ubiquinone-9. The major fatty acids were summed feature 8 (C 7 and/or C 6) and iso-C. Polar lipids included phosphatidylethanolamine, phosphatidylglycerol, a glycosphingolipid and an unidentified aminolipid. Based on the genetic, chemotaxonomic and phenotypic data, strain C5 is concluded to represent a novel species in the genus , for which the name sp. nov. is proposed. The type strain is C5 (=MCCC 1K05108=KCTC 92307).
