During a survey of microbial communities in the influent (ambient water) and effluent of a water purification facility with aeration and supplement of starch as carbon source, a novel bacterial strain, designated SZ9T, was isolated from the effluent sample. Colonies of strain SZ9T were small (approximately 0.5–1.0 mm in diameter), creamy-white, circular, smooth, translucent and convex. Cells were facultative anaerobic, motile by means of a single polar flagellum, rod-shaped, multiplied by binary fission, Gram-stain-negative, oxidase-positive and catalase-negative. Growth occurred at 10–40 °C (optimum, 28 °C) and pH 5.5–8.0 (optimum, pH 7.5). The range of NaCl concentration for growth was 0–1.0 % (w/v), with an optimum of 0–0.5 % (w/v). Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain SZ9T formed a lineage within the family Caulobacteraceae of the class Alphaproteobacteria and showed the highest 16S rRNA gene sequence similarities to Aquidulcibacter paucihalophilus TH1-2T (92.44%), followed by Vitreimonas flagellata SYSU XM001T (89.61 %), Asprobacter aquaticus DRW22-8T (89.49 %) and Hyphobacterium vulgare WM6T (89.49%). The predominant fatty acids (>10 % of the total fatty acids) of strain SZ9T was summed feature 3 (comprising C16 : 1 ω6c and/or C16 : 1 ω7c), summed feature 8 (C18 : 1 ω6c and/or C18 : 1 ω7c) and C16 : 0. The sole respiratory quinone was ubiquinone-10, and the major polar lipids were phosphatidylcholine and two unidentified glycolipids. The whole genome of strain SZ9T was 2 842 140 bp in size, including 2769 protein-coding genes, 37 tRNA genes and two rRNA genes, and the genomic G+C content was 41.4 mol%. The orthologous average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization values between strain SZ9T and other genera within the family Caulobacteraceae were 64.50–66.62 %, 46.96–54.17 % and 27.70–31.70 %, respectively. Therefore, based on the results of phenotypic, chemotaxonomic and phylogenetic analyses, the isolated strain SZ9T could be distinguished from other genera, suggesting that it represents a novel species of a novel genus in the family Caulobacteraceae , for which the name Pseudaquidulcibacter saccharophilus gen. nov., sp. nov is proposed. The type strain is SZ9T (=CCTCC AB2021029T=KCTC 82788T).

“…ampicilliniresistens from red alga Porfira yezoensis [60, 66], Henriciella algicola from green alga Nannochloris sp. [67], Litorimonas cladophorae from green alga Cladophora stimpsoni [68] and Marinicauda algicola from red alga Rhodosorus marinus [69]. Cyanobacterial consortia somewhat resemble the alga-bacterial associations, so it was not surprising to find a stalked bacterium as a satellite of a cyanobacterium.…”

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 .

Strains M65T, M69 and JN25 were isolated from seawater of the West Pacific Ocean. Cells of the three strains were Gram-stain-negative, aerobic and rod-shaped. Cells were motile by means of flagella. On the basis of the results of 16S rRNA gene sequence analysis, strains M65T, M69 and JN25 showed the highest 16S rRNA gene sequence similarity to Henriciella algicola MCS27T (98.8 %), followed by Henriciella marina DSM 19595T (98.4 %), Henriciella barbarensis MCS23T (98.4 %), Henriciella pelagia LA220T (98.3 %), Henriciella aquimarina P38T (98.1 %) and Henriciella litoralis SD10T (97.8 %). The 16S rRNA gene sequence similarities among the isolates were 100 %. Phylogenetic analyses revealed that the isolates fell within a cluster comprising the Henriciella species and represented an independent lineage. The average nucleotide identity and in silico DNA–DNA hybridization values between strain M65T and the type strains of Henriciella species were 73.9–85.8 % and 19.9–22.4 %, respectively. The sole respiratory quinone detected in the three isolates was ubiquinone 10. The principal fatty acids were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) and C16 : 0. The major polar lipids were glucuronopyranosyldiglyceride, monoglycosyldiglyceride and one unidentified glycolipid. The DNA G+C content was 61.3–61.4 mol%. Phylogenetic distinctiveness, chemotaxonomic differences, together with phenotypic properties, revealed that the isolates could be differentiated from the Henriciella species with validly published names. Therefore, it is proposed that strains M65T, M69 and JN25 represent a novel species of the genus Henriciella , for which the name Henriciella mobilis sp. nov. (type strain, M65T=CGMCC 1.15927T=KCTC 52576T) is proposed.
