Two strains of Gram-reaction-negative, rod-shaped, non-spore-forming, non-motile, aerobic bacteria, designated LW30T and LW29, were isolated from the rhizosphere of a wetland reed in Dongtan, Chongming Island, China. The strains formed pale-yellow colonies on R2A plates. Growth occurred at 4–37 °C (optimum 30 °C), at pH 6–9 (optimum pH 7–8) and in the presence of 0–3 % (w/v) NaCl (optimum 0–1 %). Oxidase and catalase activities and flexirubin-type pigments were absent. MK-6 was the major respiratory quinone. The major fatty acids were iso-C15 : 0, C15 : 0, iso-C15 : 1 G and iso-C17 : 1 ω9c. Strains LW30T and LW29 could be differentiated from related species by several phenotypic characteristics. Phylogenetic analyses based on 16S rRNA gene sequences placed strains LW30T and LW29 in the genus Flavobacterium with high sequence similarity to Flavobacterium cheniae NJ-26T (94.0 %) and Flavobacterium indicium GPTSA 100-9T (93.9 %). Together with F. indicium GPTSA 100-9T, strains LW30T and LW29 formed a distinct group in the phylogenetic tree. The DNA G+C content was 30 mol%. On the basis of the phylogenetic and phenotypic evidence, strains LW30T and LW29 represent a novel species of the genus Flavobacterium, for which the name Flavobacterium dongtanense sp. nov. is proposed. The type strain is LW30T (=KCTC 22671T =CCTCC AB 209201T).

A Gram-negative, pink-pigmented, non-motile, strictly aerobic rod, designated CNU040T, was isolated from seawater from the coast of Jeju Island in Korea. The temperature, pH and NaCl ranges for growth were 4–30 °C, pH 5.5–10.0 and 0–5.0 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CNU040T belonged to a distinct lineage in the genus Algoriphagus and exhibited high sequence similarity with Algoriphagus terrigena DS-44T (98.3 %) and Algoriphagus alkaliphilus AC-74T (96.6 %) and lower sequence similarity (<96.0 %) with all other members of the genus Algoriphagus. DNA–DNA relatedness between strain CNU040T and A. terrigena KCTC 12545T was 44.5 %. The DNA G+C content of the isolate was 48.5 mol% and the major respiratory quinone was menaquinone-7. The major cellular fatty acids were iso-C15 : 0 (28.6 %) and summed feature 3 (consisting of iso-C15 : 0 2-OH and/or C16 : 1ω7c; 24.0 %). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, one unknown amino lipid, one unknown aminophospholipid and three unknown polar lipids. On the basis of phenotypic, phylogenetic and genotypic data, strain CNU040T represents a novel species within the genus Algoriphagus, for which the name Algoriphagus jejuensis sp. nov. is proposed. The type strain is CNU040T ( = KCTC 22647T  = JCM 16112T).

Abstract A Gram-stain-negative, aerobic, rod-shaped bacterium, designated strain TRM85114T, was isolated from Jincaotan in Pamir, PR China. We found it has the ability to degrading 1-naphthylamine. Strain TRM85114T grows at 4-40 °C (optimum, 30 °C), at pH 6.0-9.0 (optimum, pH 6.0-7.0) and with 3%-15% (w/v) NaCl (optimum, 3%-6%). Phylogenetic analysis of 16S rRNA gene sequences revealed that strain TRM85114T is affiliated with the genus Halomonas, sharing high sequence similarity (97.3%) with the type strain of Halomonas korlensis CGMCC 1.6981T. The major fatty acids of strain TRM85114T are C12:0 3-OH, C16:0, C17:0 cyclo, C19:0 cyclo ω8c, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) and summed feature 8 (C18:1 ω6c and/or C18:1 ω7c). The predominant respiratory quinone is Q-7. The genomic DNA G + C content of strain TRM85114T was determined to be 61.6 mol%. Calculating the average nucleotide identities and the digital DNA-DNA hybridization values between strain TRM85114T and the related type Halomonas strains further revealed that TRM85114T represented a novel species of the genus Halomonas. The name Halomonas jincaotanensis sp. nov. is proposed. The type strain is TRM85114T (CCTCC AB 2021006T =LMG 32311T).

A Gram-stain-negative, heterotrophic, aerobic, non-spore-forming and non-motile bacterial strain, designated LM5T, was isolated from activated sludge from a sequencing batch reactor for the treatment of effluents contaminated by malachite green. The taxonomy of strain LM5T was studied by phenotypic and phylogenetic methods. Strain LM5T formed orange colonies on R2A and YP plates. Cells were rods, 0.4–0.6 μm in diameter and 0.8–1.2 μm in length. Growth occurred at 10–35 °C (optimum, 20–25 °C), at pH 5.5–9.5 (optimum, pH 6.5–7.5) and in the presence of 0–2 % (w/v) NaCl (optimum, 0.5 %). Oxidase and catalase activities were present. Flexirubin-type pigments were present, but extracellular glycans were absent. MK-6 was the major respiratory quinone. The major fatty acids were iso-C15 : 0 (28.3 %) and iso-C17 : 1 ω9c (13.8 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LM5T was a member of the genus Flavobacterium with highest sequence similarity to Flavobacterium soli DS-6T (93.2 %) and Flavobacterium lindanitolerans IP-10T (92.9 %). Together with F. lindanitolerans IP-10T, strain LM5T formed a distinct lineage in the phylogenetic tree. The DNA G+C content was 52±0.6 mol% (HPLC), which is significantly higher than that of other species of the genus Flavobacterium (30–41 mol%). Based on phylogenetic and phenotypic evidence, strain LM5T is considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium caeni sp. nov. is proposed; the type strain is LM5T (=CGMCC 1.7031T=NBRC 104239T).
