A bacterial strain, designated YZGR15T, was isolated from the root of an annual halophyte Suaeda aralocaspica, collected from the southern edge of the Gurbantunggut desert, north-west PR China. Cells of the isolate were Gram-stain-positive, facultatively anaerobic, irregular rods. Growth occurred at 4–42 °C (optimum, 30–37 °C), at pH 6.0–9.0 (optimum, pH 7.0–7.5) and in the presence of 0–9 % (w/v) NaCl (optimum, 2–5 %). Phylogenetic analysis using 16S rRNA gene sequences indicated that strain YZGR15T showed the highest sequence similarity to Sanguibacter keddieii (98.27 %), Sanguibacter antarcticus (98.20 %) and Sanguibacter inulinus (98.06 %). Results of genome analyses of strain YZGR15T indicated that the genome size was 3.16 Mb, with a genomic DNA G+C content of 71.9 mol%. Average nucleotide identity and digital DNA–DNA hybridization values between strain YZGR15Tand three type strains were in the range of 76.5–77.8 % and 20.0–22.2 %, respectively. Analysis of the cellular component of strain YZGR15T revealed that the primary fatty acids were anteiso-C15 : 0, C16 : 0, C14 : 0 and iso-C16 : 0 and the polar lipids included diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids and two unidentified glycolipids. The cell-wall characteristic amino acids were glutamic acid, alanine and an unknown amino acid. The whole-cell sugars for the strain were mannose, ribose, rhamnose, glucose and an unidentified sugar. The predominant respiratory quinone was MK-9(H4). Based on the results of genomic, phylogenetic, phenotypic and chemotaxonomic analyses, strain YZGR15T represents a novel species of the genus Sanguibacter , for which the name Sanguibacter suaedae sp. nov. is proposed. The type strain is YZGR15T (=CGMCC 1.18691T=KCTC 49659T)

A novel bacterial strain, designated as HN-E44T, was isolated from marine sponge collected from Yangpu Bay, Hainan, PR China. Strain HN-E44T was Gram-stain-negative, non-motile, catalase-positive, oxidase-negative, rod-shaped and yellow-pigmented. Growth occurred at 4–37 °C (optimum, 28 °C), at pH 6–8 (pH 7) and in 0.5–14 % (w/v) NaCl (3–5 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HN-E44T formed an independent cluster with Marixanthomonas ophiurae JCM 14121T within the family Flavobacteriaceae and had the highest sequence similarity of 93.6 % to the closest type strain M. ophiurae JCM 14121T. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0 3-OH, summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) and iso-C15 : 1 G. The polar lipids comprised phosphatidylethanolamine, sphingolipid, four unidentified phospholipids, an unidentified aminophospholipid and an unidentified lipid. The respiratory quinone was identified as MK-6. The genomic DNA G+C content was determined to be 40.6 mol%. The average nucleotide identity (ANI) and average amino acid identity (AAI) values between strain HN-E44T and closest type strain M. ophiurae JCM 14121T were, respectively, 79.6 and 85.2 %, both of which were below thresholds for species delineation (95–96 % ANI and 95–96 % AAI), but were over thresholds for genus delineation (73.98 % ANI and 70–76 % AAI). The combined genotypic and phenotypic distinctiveness demonstrated that strain HN-E44T could be differentiated from closely related genera. Therefore, it is proposed that strain HN-E44T represents a novel species of the genus Marixanthomonas , for which the name Marixanthomonas spongiae sp. nov. is proposed, with the type strain HN-E44T (=MCCC 1K03332T=LMG 30459T).

A novel Gram-stain-negative, aerobic and rod-shaped halophilic archaeon, designated HD8-45T, was isolated from the red brine of salted brown alga Laminaria produced at Dalian, PR China. According to the results of 16S rRNA gene and rpoB′ gene sequence comparisons, strain HD8-45T showed the highest sequence similarity to the corresponding genes of Salinirussus salinus YGH44T (95.1 and 85.2 % similarities, respectively), Halovenus aranensis EB27T (91.2 and 86.0 % similarities, respectively). The low sequence similarity and the phylogeny implied the novel generic status of strain HD8-45T. Genomic relatedness analyses showed that strain HD8-45T were clearly distinguished from other species in the order Halobacteriales , with average nucleotide identity, amino acid identity and in silico DNA–DNA hybridization values not more than 75.1, 65.6 and 21.5 %. The polar lipid pattern contained phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, two major glycolipids and two minor glycolipids. The two major glycolipids and a minor glycolipid were chromatographically identical to disulfated mannosyl glucosyl diether, sulfated mannosyl glucosyl diether and mannosyl glucosyl diether, respectively. The major respiratory quinones were menaquinone MK-8 and MK-8(H2). The DNA G+C content was 62.0 mol% (Tm ) and 61.9 mol% (genome). All these results showed that strain HD8-45T represents a novel species of a new genus in the order Halobacteriales , for which the name Salinibaculum litoreum gen. nov., sp. nov. is proposed. The type strain of Salinibaculum litoreum is HD8-45T (=CGMCC 1.15328T=JCM 31107T).
