A Gram-staining-negative, rod-shaped, gliding and pale-pink-pigmented bacterium, designated strain ZLM-10T, was isolated from a soil sample collected from an arid area in Xinjiang province, China, and characterized in a taxonomic study using a polyphasic approach. The novel strain grew optimally at 30–37 °C and in the presence of 2 % (w/v) sea salts. The only respiratory quinone detected was MK-7 and the major cellular fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and two unidentified aminophospholipids. The DNA G+C content was 45.4 mol%. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZLM-10T was a member of the phylum Bacteroidetes and appeared most closely related to Cesiribacter roseus 311T (90.2 % sequence similarity), Marivirga sericea LMG 13021T (89.2 %), Cesiribacter andamanensis AMV16T (89.1 %) and Marivirga tractuosa DSM 4126T (89.1 %). On the basis of phenotypic and genotypic data and phylogenetic inference, strain ZLM-10T should be classified as a novel species of a new genus in the family Flammeovirgaceae , for which the name Nafulsella turpanensis gen. nov., sp. nov. is proposed. The type strain of the type species is ZLM-10T ( = CCTCC AB 208222T = KCTC 23983T).

A prosthecate bacterial strain, designated G-192T, was isolated from decaying biomass of a haloalkaliphilic cyanobacterium Geitlerinema sp. Z-T0701. The cells were aerobic, Gram-negative, non-endospore-forming and dimorphic, occurring either as sessile bacteria with a characteristic stalk or as motile flagellated cells. The strain utilized a limited range of substrates, mostly peptonaceous, but was able to degrade whole proteins. Growth occurred at 5–46 °C (optimum, 35–40 °C), pH 7.3–10.3 (optimum, pH 8.0–9.0), 0–14 % NaCl (v/w; optimum, 2.0–6.0 %, v/w). The G+C content of the genomic DNA of strain G-192T was 66.8%. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain G-192T formed a distinct evolutionary lineage within the family Hyphomonadaceae . Strain G-192T showed the highest 16S rRNA sequence similarity to Glycocaulis profundi ZYF765T (95.2%), Oceanicaulis stylophorae GISW-4T (94.2%) and Marinicauda salina WD6-1T (95.5%). The major cellular fatty acids (>5% of the total) were C18:1 ω9c, C18:0 and 11-methyl-C18:1 ω7c. The major polar lipids were glycolipids and phospholipids. The only respiratory quinone was ubiquinone-10 (Q-10). Based on polyphasic results including phylogenomic data, the novel strain could be distinguished from other genera, which suggests that strain G-192T represents a novel species of a new genus, for which the name Alkalicaulis satelles gen. nov., sp. nov. is proposed. The type strain is G-192T (=VKM B-3306T=KCTC 72746T). The strain is the first representative of the stalked bacteria associated with a haloalkaliphilic cyanobacterium. Based on phylogenomic indices and phenotypic data, it is proposed to evolve two novel families Maricaulaceae fam. nov. and Robiginitomaculaceae fam. nov. out of the current family Hyphomonadaceae . In addition, it is proposed to place the first two families in the novel order Maricaulales ord. nov. and novel order Hyphomonadales ord. nov. is proposed to accommodate the family Hyphomonadaceae .

Cells were non-spore-forming rods, catalase- and oxidase-positive, motile by gliding and facultatively anaerobic. The only respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 1 G. The G+C content of the genomic DNA was 47.5±1.0 mol%. In addition to phosphatidylethanolamine, the major polar lipids were two unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The major cell-wall sugars were ribose, xylose and galactose. It is proposed that strain DCY13T represents a novel species in the genus Sediminibacterium , for which the name Sediminibacterium ginsengisoli sp. nov. is proposed. The type strain is DCY13T ( = KCTC 12833T  = JCM 15794T  = DSM 22335T). Emended descriptions of the genus Sediminibacterium and of Sediminibacterium salmoneum are also proposed.

A Gram-staining-negative bacterium, strain TS-T86T, was isolated from Lake Tuosu, a saline lake (salinity 5.4 %, w/w) in Qaidam basin, China. Its taxonomic position was determined by using a polyphasic approach. Strain TS-T86T was strictly heterotrophic, aerobic and catalase- and oxidase-positive. Cells were non-spore-forming, non-motile rods, 0.4–0.6 µm wide and 1.2–2.3 µm long. Growth was observed in the presence of 0–9.0 % (w/v) NaCl (optimum, 2.0 %), at 4–35 °C (optimum, 25 °C) and at pH 7.0–10.5 (optimum, pH 8.5–9.0). Strain TS-T86T contained MK-7 as the predominant respiratory quinone. The major fatty acids (>10 %) were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipids consisted of phosphatidylethanolamine, an unknown phospholipid, six unidentified aminolipids and two uncharacterized lipids. The DNA G+C content was 35 mol% (T m). Phylogenetic trees based on 16S rRNA gene sequences showed that strain TS-T86T was associated with the genus Belliella , and showed the highest sequence similarity to Belliella baltica BA134T (98.5 %) and then to Belliella kenyensis No.164T (95.7 %) and Belliella pelovolcani CC-SAL-25T (95.3 %). DNA–DNA relatedness of strain TS-T86T to Belliella baltica DSM 15883T was 32±3 %.

A Gram-stain-negative, oxidase-positive, catalase-positive, aerobic, orange-pigmented, rod-shaped and non-motile bacterium designated strain MMS17-SY002T was isolated from island soil. The isolate grew at 20–37 °C (optimum, 30 °C), at pH 6.0–9.5 (optimum, pH 7) and in the presence of 0.5–4.0 % (w/v) NaCl (optimum, 2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MMS17-SY002T was mostly related to the genus Muriicola of the family Flavobacteriaceae and had highest sequence similarity of 96.82 % to Muriicola marianensis A6B8T and Muriicola jejuensis EM44T, but formed a distinct phylogenetic line within the genus. Chemotaxonomic analyses showed that menaquinone 6 was the predominant isoprenoid quinone, the major fatty acids were iso-C15 : 1 G and iso-C15 : 0, and the diagnostic polar lipid was phosphatidylethanolamine. The genomic DNA G+C content was 42.4 mol%. Strain MMS17-SY002T could be distinguished from related species by the combination of trypsin, α-chymotrypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase, α-galactosidase, β-galactosidase and β-glucosidase activities. The orthologous average nucleotide identity between the genomes of strain MMS17-SY002T and M. jejuensis and that between the strain and M. marianensis A6B8T were 73.26 and 73.33%, respectively, thus confirming the separation of the strain from related species at species level. Based on the phenotypic, phylogenetic, chemotaxonomic and genomic characterization, MMS17-SY002T should be recognized as a novel species of the genus Muriicola , for which the name Muriicola soli sp. nov. is proposed. The type strain is MMS17-SY002T (=KCTC 62790T=JCM 32370T).
