A novel aerobic, Gram-staining-negative bacterium, designated strain LAM-WHM-ZCT, was isolated from coastal sediment samples from the Bohai Sea, near Yantai, China. Cells of LAM-WHM-ZCT were non-motile, short-rod- or coccoid-shaped. The temperature and pH ranges for growth were 4–40  °C (optimum: 20–33  °C) and pH 5–9 (optimum: pH 7.5). The strain did not require NaCl for growth but tolerated up to 10 % NaCl (w/v). The major fatty acids of strain LAM-WHM-ZCT were summed feature 3, C12 : 0, C16 : 0, summed feature 2 and summed feature 8. The predominant respiratory quinone was ubiquinone Q-8. The main polar lipids were diphosphatidyglycerol, phosphatigylethanolamine, phosphatidyglycerol, one phospholipid and four unidentified glycolipids. The DNA G+C content was 59.3 mol% as determined by the melting temperature (T m) method. Analysis of the 16S rRNA gene sequence indicated that the isolate represented a member of the genus Oceanisphaera and was closely related to Oceanisphaera arctica KCTC 23013T, Oceanisphaera litoralis DSM 15406T, Oceanisphaera sediminis KACC 15117T and Oceanisphaera donghaensis KCTC 12522T with 97.7 %, 97.1 %, 96.6 % and 96.6 % sequence similarity, respectively. The DNA–DNA hybridization values between strain LAM-WHM-ZCT and the four reference strains were 47.4 ± 2.8 %, 33.5 ± 2.2 %, 28.4 ± 1.8 % and 13.7 ± 0.8 %, respectively. Based on its phenotypic and genotypic properties, strain LAM-WHM-ZCT is suggested to represent a novel species of the genus Oceanisphaera, for which the name Oceanisphaera psychrotolerans sp. nov. is proposed. The type strain is LAM-WHM-ZCT ( = ACCC 06516T = JCM 30466T).

A novel Gram-staining-negative, non-spore-forming, non-flagellated, non-motile, aerobic, saffron-coloured, rod-shaped bacterium that did not produce flexirubin-type pigments was designated strain EM7T and was distinct from other members of the genus Bizionia by produce carotenoid-type pigments and being able to grow independently of NaCl. Strain EM7T was isolated from the intestinal tract of an egg cockle, Fulvia mutica, which had been collected from the West Sea in Korea. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain EM7T belonged to the genus Bizionia, and showed sequence similarity to Bizionia paragorgiae KMM 6029T (97.9 %) and Bizionia saleffrena HFDT (97.73 %). Growth occurred on marine agar 2216 at 0–25 °C (optimum, 20 °C) and at pH 6–9 (optimum, pH 7). Growth occurred in the presence of 0–10 % (w/v) NaCl (optimum, 2 %, w/v, NaCl). The major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C15 : 1 G, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C17 : 0 3-OH and iso-C16 : 0 3-OH. The major respiratory quinone was menaquinone MK-6. The polar lipids of strain EM7T comprised phosphatidylethanolamine, three unidentified aminolipids, an unidentified aminophospholipid and two unidentified lipids. The genomic DNA G+C content was 34.8 mol%. Bizionia paragorgiae KMM 6029T and Bizionia saleffrena HFDT to Bizionia paragorgiae KCTC 12304T and Bizionia saleffrena CIP 108534T, respectively. Thus, it is proposed that the isolate represents a novel species, Bizionia fulviae sp. nov., with strain EM7T ( = KACC 18255T = JCM 30417T) as the type strain.

The main fatty acids are iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH, iso-C15:0 3-OH, C16:0. Phosphatidylethanolamine (PE), three unidentified aminolipids (AL1, AL2, AL3) and one unidentified lipid (L) were the major polar lipids. The G+C content of the genomic DNA was 33.9 mol%. Strain XSD401T had the highest sequence similarity (96.88%) to the 16S rRNA gene of Psychroserpens damuponensis KCTC 23539T. The similarities with Psychroserpens burtonensis DSM 12212T was 96.31%. The dDDH values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T, were 20.40% and 20.30%, respectively. The average nucleotide identity (ANI) values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T were 76.91%, 76.88%, respectively. The differences in morphology, physiology and genotype from the previously described taxa support the classification of strain XSD401T as a representative of a novel species of the genus Psychroserpens, for which the name Psychroserpens luteus sp. nov. is proposed. The type strain is XSD401T (= MCCC 1H00396T = KCTC 72684T = JCM 33931T).
