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 %. It is concluded that strain TS-T86T represents a novel species of the genus Belliella , for which the name Belliella aquatica sp. nov. is proposed. The type strain is TS-T86T ( = CGMCC 1.12479T = JCM 19468T).

The strain contained menaquinone-6 (MK-6) as the respiratory quinone. The polar lipids detected in the strain were phosphatidylethanolamine and unknown aminophospholipids, aminolipids and polar lipids. On the basis of phylogenetic distinction and differential phenotypic characteristics, it is suggested that strain IMCC3317T ( = KCTC 32292T = NBRC 109401T) be assigned to the genus Kordia as the type strain of a novel species, for which the name Kordia antarctica sp. nov. is proposed.

A taxonomic study was carried out on five Gram-staining-negative, catalase- and oxidase-positive, rod-shaped bacteria isolated from the gills and livers of five diseased rainbow trout. The five novel isolates were designated strains 687B-08T, 445-08, 452-08, 453B-08 and 967B-08. In phylogenetic analyses based on 16S rRNA gene sequences, the five novel strains appeared almost identical (99.0–100 % sequence similarity) and to belong to the genus Chryseobacterium . Strain 687B-08T (the strain selected to represent the five novel isolates) was found to be most closely related to Chryseobacterium oncorhynchi 701B-08T (98.9 % sequence similarity), Chryseobacterium ureilyticum F-Fue-04IIIaaaaT (98.6 %), Chryseobacterium indologenes ATCC 29897T (98.3 %), Chryseobacterium jejuense JS17-8T (98.1 %) and Chryseobacterium gleum ATCC 35910T (98.1 %). In DNA–DNA hybridizations, DNA–DNA relatedness values of 99–100 % were recorded between the five novel strains. Lower DNA–DNA relatedness values (21–57 %) were recorded between strain 687B-08T and C. oncorhynchi 701B-08T, C. ureilyticum F-Fue-04IIIaaaaT and the type strains of other closely related, established species of the genus Chryseobacterium . The predominant respiratory quinone of strain 687B-08T was MK-6 and the major cellular fatty acids were iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 0 3-OH and C16 : 1ω6c. The G+C content of the genomic DNA of strain 687B-08T was 38.6 mol%. Based on the phenotypic and genotypic evidence, the five novel strains isolated from rainbow trout represent a single, novel species of the genus Chryseobacterium , for which the name Chryseobacterium viscerum sp. nov. is proposed. The type strain is 687B-08T ( = CECT 7793T  = CCUG 60103T).
