“…The phylogenetic analyses and 16S rRNA gene similarity comparison indicated that strain XY-114 T belonged to the genus Algibacter and represented a novel species. Our results supported the reclassification of Arenitalea lutea as Algibacter lutea , Algibacter aquaticus as Flavivirga aquaticus , and Algibacter alginicilyticus as Pseudalgibacter alginicilyticus , proposed by Sun et al [6]. However, Alg.…”

“…Recently, Algibacter aquaticus , Algibacter alginolytica and Arenitalea lutea were proposed to be reclassified as Flavivirga aquatic , Pseudalgibacter alginicilyticus and Algibacter lutea , while Algibacter wandonensis was proposed to be a later heterotypic synonym of Algibacter lectus by Sun et al . in 2021 (waiting for validation) [6]. Before the proposal of Sun et al .…”

“…Finally, after conducting a series of comparative analyses, including phenotypic and phylogenetic characterization, as well as genome relatedness investigations, we agree with the proposal of Sun et al . [6], except for transferring Algibacter aestuarii to the genus Hyunsoonleella , it should instead be affiliated to the genus Algibacter .…”

A novel symbiotic bacterium, designated strain XY-114T, was isolated from the cerata of an Onchidium marine invertebrate species collected in the South China Sea. Strain XY-114T was an aerobic, Gram-stain-negative, non-motile and short rod-shaped bacterium (0.5–0.8 µm wide and 1.0–1.5 µm long) without flagellum. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XY-114T belonged to the genus Algibacter with the highest similarity of 97.2 % to the closest phylogenetic relative Algibacter aestuarii KYW371T. Cells grew at 15–37 °C (optimum, 30 °C), at pH 5.5–9.0 (optimum 7.0–8.0) and at NaCl concentrations of 0.5–5.0 % (w/v; optimum 1.5–3.0 %). The major fatty acids (>10 %) were summed feature 3 (comprising C16 : 1 ω7c and/or C16 : 1 ω6c), iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The predominant polar lipid was phosphatidylethanolamine. The predominant respiratory quinone was MK-6. Flexirubin-type pigments were absent. The genome size of strain XY-114T was 3.4 Mbp, with 34.9 mol% of DNA G+C content. The average nucleotide identity, digital DNA–DNA hybridization and amino acid identity values between strain XY-114T and A. aestuarii KYW371T were 74.5 %, 17.0±1.8 % and 73.9 %. Characterization based on phylogenetic, phenotypic, chemotaxonomic and genomic evidence demonstrated that strain XY-114T represents a novel species of the genus Algibacter , for which the name Algibacter onchidii sp. nov. is proposed. The type strain is XY-114T (=KCTC 72217T=MCCC 1K03606T).

A novel Gram-stain-negative, aerobic, non-motile, rod-shaped and yellow-pigmented bacterial strain, designated HU1-3T, was isolated from Ulva in China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HU1-3T represented a member of the genus Hyunsoonleella within the family Flavobacteriaceae , phylum Bacteroidota , and showed the highest 16S rRNA gene sequence similarity to Hyunsoonleella flava T58T (97.6 %). Strain HU1-3T grew at 15–35 °C (optimum, 25–30 °C), pH 6.0–8.0 (optimum, pH 7.0) and in the presence of 2–6 % (w/v) NaCl (optimum, 2–4 %). The draft genome of strain HU1-3T comprised 4.1 Mbp with a G+C content of 33.9mol%. Compared with the reference strain Hyunsoonleella jejuensis CNU004T, the average nucleotide identity value of strain HU1-3T was 77.9 %. The major fatty acids (>10 % of the total) were iso-C15 : 0, iso G-C15 : 1 and iso-C17 : 0 3-OH. MK-6 was the major respiratory quinone. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids, and three unknown polar lipids. Many genes that encode glycoside hydrolases (e.g. glucosidase, xylosidase, mannosidase, galactosidase, etc.) were annotated in the genome of strain HU1-3T, which indicated that it might have the ability to degrade various kinds of polysaccharides. Given the phylogenetic, chemotaxonomic, biochemical and genomic data, strain HU1-3T is considered to represent a novel species of the genus Hyunsoonleella , for which the name Hyunsoonleella ulvae sp. nov. is proposed. The type strain is HU1-3T (=KCTC 82511T=MCCC 1K05798T).
