Henriciella litoralis sp. nov., isolated from a tidal flat, transfer of Maribaculum marinum Lai et al. 2009 to the genus Henriciella as Henriciella aquimarina nom. nov. and emended description of the genus Henriciella Lee, Se Hee and Shim, Jae Kuk and Kim, Jeong Myeong and Choi, Hyung-Kyoon and Jeon, Che Ok,, 61, 722-727 (2011), doi = https://doi.org/10.1099/ijs.0.020396-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A Gram-staining-negative, strictly aerobic bacterium, designated strain SD10T, was isolated from a tidal flat of the Yellow Sea, South Korea. Cells were non-spore-forming rods that showed catalase- and oxidase-positive reactions. Growth of strain SD10T was observed at 15–40 °C (optimum, 25–30 °C), at pH 6.0–9.0 (optimum, pH 6.5–8.5) and in the presence of 1–10 % (w/v) NaCl. Strain SD10T contained ubiquinone-10 (Q-10) as a major isoprenoid quinone and C18 : 1ω7c (39.3 %), C16 : 0 (20.2 %), C17 : 0 (8.9 %) and C17 : 1ω6c (8.1 %) as major fatty acids. The cellular polar lipids were identified as phosphatidylglycerol, monoglycosyldiglyceride, glucuronopyranosyldiglyceride and two unidentified glycolipids. The G+C content of the genomic DNA was 55.2 mol%. Based on 16S rRNA gene sequence similarities, the strain was most closely related to Henriciella marina Iso4T and Maribaculum marinum P38T, with similarities of 97.8 and 97.0 %, respectively. The DNA–DNA relatedness between strain SD10T and H. marina Iso4T was 12.0±3.2 %. A phylogenetic analysis based on 16S rRNA gene sequences showed that M. marinum P38T and H. marina Iso4T formed a monophyletic cluster and that their 16S rRNA gene sequence similarity was 98.1 %. DNA–DNA hybridization between H. marina Iso4T and M. marinum LMG 24711T was 22.9±2.7 %, indicating that the two strains belong to separate species. On the basis of chemotaxonomic data and molecular properties, we propose that strain SD10T represents a novel species of the genus Henriciella, for which the name Henriciella litoralis sp. nov. is proposed. The type strain is SD10T ( = KACC 13700T  = DSM 22014T). In addition, we propose to transfer Maribaculum marinum Lai et al. 2009 to the genus Henriciella as Henriciella aquimarina nom. nov. (type strain P38T  = CCTCC AB 208227T  = LMG 24711T  = MCCC 1A01086T), and we present an emended description of the genus Henriciella., language=, type=
