ABSTRACT
The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4-42 °C (optimally at 30-35 °C), at pH 7.0-10 (optimally at pH 9) and in the presence of 0.5-8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15  0 and anteiso-C15  0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA-DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita, for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).
