A Gram-stain-negative, aerobic, motile, orange-pigmented, slightly halophilic, rod-shaped bacterium, designated strain JAMH 0132T, was isolated from the trophosome of a tubeworm in Kagoshima Bay, Japan, and its taxonomic position was investigated using a polyphasic approach. The novel strain grew optimally at 28–30 °C and with about 2.0 % (w/v) NaCl. Chemotaxonomic analysis showed that Q-10 was the predominant respiratory quinone and that C18 : 1ω7c, C16 : 0 2-OH and C16 : 0 were the major fatty acids. Sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine were the major polar lipids. The genomic DNA G+C content was 60.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JAMH 0132T belonged to the family Sphingomonadaceae , within the class Alphaproteobacteria . The novel strain appeared most closely related to Sphingopyxis baekryungensis SW-150T (95.1 % 16S rRNA gene sequence similarity) and showed less sequence similarity with representatives of the genera Blastomonas , Sphingomonas , Sphingosinicella and Novosphingobium (<94.8 %). In having no detectable polyamine, strain JAMH 0132T differed from members of all genera currently in the family Sphingomonadaceae . On the basis of its phenotypic properties and phylogenetic distinctiveness, strain JAMH 0132T represents a novel species of a new genus in the family Sphingomonadaceae for which the name Parasphingopyxis lamellibrachiae gen. nov., sp. nov. is proposed. The type strain of Parasphingopyxis lamellibrachiae gen. nov., sp. nov. is JAMH 0132T ( = JCM 15549T  = NCIMB 14486T).

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 .

Three Gram-staining-negative, strictly aerobic, non-pigmented, non-motile, rod-shaped bacterial strains, SP32T ( = SLM-1T), SR68 ( = SLM-3) and SP95 ( = SLM-2), were isolated from two water samples of a cold-water lake in Xinjiang province, China. Growth was observed at 4–25 °C and pH 6.0–9.0, and optimum growth occurred at 18–20 °C and at pH 7.0–7.5. Phylogenetic analysis of 16S rRNA gene sequences revealed that these isolates belonged to the family Rhodobacteraceae , but formed an evolutionary lineage distinct from other species of this family with validly published names. Strain SP32T showed the highest 16S rRNA gene sequence similarity (96.7 %) to Rhodobacter veldkampii ATCC 35703T, and the similarity to members of the genera Defluviimonas , Haematobacter and Pseudorhodobacter was respectively 95.8–96.4, 96.0–96.1 and 95.3–96.1 %. The genomic DNA G+C content of strain SP32T was 67.6 mol%. The major fatty acids (>5 %) were summed feature 8 (C18 : 1ω7c/C18 : 1ω6c) and11-methyl C18 : 1ω7c. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, one unidentified glycolipid and one unidentified polar lipid were the main polar lipids. Ubiquinone 10 (Q-10) was the sole respiratory quinone. Strain SP32T did not produce photosynthetic pigments and did not contain the gene pufM, by which it differed from the phototrophic species of the family Rhodobacteraceae . Based on its distinct phenotypic, chemotaxonomic and phylogenetic properties, strain SP32T represents a novel species in a novel genus within the family Rhodobacteraceae , for which we propose the name Frigidibacter albus gen. nov., sp. nov. The type strain of Frigidibacter albus is strain SP32T ( = SLM-1T = CGMCC 1.13995T = NBRC 109671T).

Two Gram-stain-negative and non-flagellated bacteria, YSTF-M3T and YSTF-M6T, were isolated from a tidal flat from Yellow Sea, Republic of Korea, and subjected to a polyphasic taxonomic study. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strains YSTF-M3T and YSTF-M6T belong to the genera Kordia and Olleya of the family Flavobacteriaceae , respectively. The 16S rRNA gene sequence similarities between strain YSTF-M3T and the type strains of Kordia species and between strain YSTF-M6T and the type strains of Olleya species were 94.1–98.4 and 97.3–98.3 %, respectively. The ANI and dDDH values between genomic sequences of strain YSTF-M3T and the type strains of five Kordia species and between those of strain YSTF-M6T and the type strains of three Olleya species were in ranges of 77.0–83.2 and 20.7–27.1 % and 79.4–81.5 and 22.3–23.9 %, respectively. The DNA G+C contents of strain YSTF-M3T and YSTF-M6T from genomic sequences were 34.1 and 31.1 %, respectively. Both strains contained MK-6 as predominant menaquinone and phosphatidylethanolamine as only major phospholipid identified. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strains YSTF-M3T and YSTF-M6T are separated from recognized species of the genera Kordia and Olleya , respectively. On the basis of the data presented, strains YSTF-M3T (=KACC 21639T=NBRC 114499T) and YSTF-M6T (=KACC 21640T=NBRC 114500T) are considered to represent novel species of the genera Kordia and Olleya , respectively, for which the names Kordia aestuariivivens sp. nov. and Olleya sediminilitoris sp. nov. are proposed.
