A polyphasic taxonomic study was performed on strain YM26-026T, which was isolated from acid-treated sediment in Kamaishi, Japan. The bacterial cells were pale-pink-pigmented, Gram-negative, obligately aerobic, non-spore-forming, spherical and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel isolate was a member of the phylum ‘Verrucomicrobia’ and shared approximately 84–87 % sequence similarity with strains of the class Opitutae that have been cultivated to date. Strain YM26-026T produced pale-pink pigments of carotenoid. β-Lactam antibiotic susceptibility tests and amino acid analysis of cell-wall hydrolysates indicated that the novel isolate did not contain muramic acid or diaminopimelic acid in the cell wall, suggesting that the strain lacks peptidoglycan. The G+C content of the DNA of strain YM26-026T was 54.0 mol%. Menaquinone-7 was the major quinone and C14 : 0 and C18 : 1 ω9c were the major fatty acids. On the basis of polyphasic taxonomic studies, it was concluded that strain YM26-026T represents a new genus of the family Puniceicoccaceae within the phylum ‘Verrucomicrobia’, for which the name Cerasicoccus arenae gen. nov., sp. nov. is proposed. The type strain is YM26-026T (=MBIC08280T=KCTC 12870T).

An obligately aerobic, spherical, non-motile, pale-yellow pigmented bacterium was isolated from a piece of leaf of seagrass, Enhalus acoroides (L.f.) Royle, grown in Okinawa, Japan and was subjected to a polyphasic taxonomic study. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the novel isolate N5FB36-5T shared approximately 96–98 % sequence similarity with the species of the genus Pelagicoccus of the family Puniceicoccaceae within the phylum ‘Verrucomicrobia’. The DNA–DNA relatedness values of strain N5FB36-5T with Pelagicoccus mobilis 02PA-Ca-133T and Pelagicoccus albus YM14-201T were below 70 %, which is accepted as the phylogenetic definition of a novel species. β-Lactam antibiotic susceptibility test and amino acid analysis of the cell wall hydrolysates indicated the absence of muramic acid and diaminopimelic acid in the cell walls, which suggested that this strain lacks an ordinary Gram-negative type of peptidoglycan in the cell wall. The DNA G+C content of strain N5FB36-5T was 51.6 mol%; MK-7 was the major menaquinone; and the presence of C16 : 0, C16 : 1 ω7c and anteiso-C15 : 0 as the major cellular fatty acids supported the identification of the novel isolate as a member of the genus Pelagicoccus. On the basis of polyphasic taxonomic data, it was concluded that this strain should be classified as a novel species of the genus Pelagicoccus, for which the name Pelagicoccus croceus sp. nov. is proposed. The type strain is N5FB36-5T (=MBIC08282T=KCTC 12903T).

A rod shaped, Gram-stain-negative, chemo-organotrophic, heterotrophic, strictly aerobic, non-gliding bacterium, designated strain PLRT, was isolated from faeces of the mollusc Aplysia punctata (Mollusca, Gastropoda) that had been fed with green algae belonging to the genus Ulva. The novel strain was able to degrade ulvan, a polysaccharide extracted from green algae (Chlorophyta, Ulvophyceae). The taxonomic position of strain PLRT was investigated by using a polyphasic approach. Strain PLRT was dark orange, oxidase-positive, catalase-positive and grew optimally at 25 °C, at pH 7.5 and in the presence of 2.5 % (w/v) NaCl with an oxidative metabolism using oxygen as the electron acceptor. Nitrate could not be used as the electron acceptor. Strain PLRT had a Chargaff’s coefficient (DNA G+C content) of 35.3 mol%. Phylogenetic analysis based on the sequence of the 16S rRNA gene placed the novel strain in the family Flavobacteriaceae (phylum ‘Bacteroidetes’), within a clade comprising Stenothermobacter spongiae, Nonlabens tegetincola, Sandarakinotalea sediminis, Persicivirga xylanidelens and Persicivirga dokdonensis. The closest neighbours of strain PLRT were P. xylanidelens and P. dokdonensis, sharing 95.2 and 95.5 % 16S rRNA gene sequence similarity, respectively. Phylogenetic inference and differential phenotypic characteristics demonstrated that strain PLRT represents a novel species of the genus Persicivirga, for which the name Persicivirga ulvanivorans sp. nov. is proposed. The type strain is PLRT ( = CIP 110082T = DSM 22727T).
