An obligately aerobic, Gram-negative, non-spore-forming, non-motile, spherical bacterium, designated strain 04OKA010-24T, was isolated from seawater surrounding the hard coral Galaxea fascicularis L., collected at Majanohama, Akajima, Japan, and was subjected to a polyphasic taxonomic study. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain represented a member of the phylum ‘Verrucomicrobia’ and shared 84–95 % sequence similarity with cultivated strains of ‘Verrucomicrobia’ subdivision 4. Amino acid analysis of the cell-wall hydrolysate indicated the absence of muramic acid and diaminopimelic acid, which suggested that the strain did not contain peptidoglycan in the cell wall. The G+C content of the DNA was 53.9 mol%. MK-7 was the major menaquinone and C14 : 0, C18 : 1 ω9c and C18 : 0 were the major fatty acids. On the basis of these data, it was concluded that strain 04OKA010-24T represents a novel species in a new genus in subdivision 4 of the phylum ‘Verrucomicrobia’, for which the name Coraliomargarita akajimensis gen. nov., sp. nov. is proposed. The type strain of Coraliomargarita akajimensis is 04OKA010-24T (=MBIC06463T=IAM 15411T=KCTC 12865T).

A thermophilic, anaerobic, chemolithoautotrophic bacterium was isolated from the walls of an active deep-sea hydrothermal vent chimney on the East Pacific Rise at 9° 50′ N. Cells of the organism were Gram-negative, motile rods that were about 1·0 μm in length and 0·6 μm in width. Growth occurred between 60 and 80 °C (optimum at 75 °C), 0·5 and 4·5 % (w/v) NaCl (optimum at 2 %) and pH 5 and 7 (optimum at 5·5). Generation time under optimal conditions was 1·57 h. Growth occurred under chemolithoautotrophic conditions in the presence of H2 and CO2, with nitrate or sulfur as the electron acceptor and with concomitant formation of ammonium or hydrogen sulfide, respectively. Thiosulfate, sulfite and oxygen were not used as electron acceptors. Acetate, formate, lactate and yeast extract inhibited growth. No chemoorganoheterotrophic growth was observed on peptone, tryptone or Casamino acids. The genomic DNA G+C content was 54·6 mol%. Phylogenetic analyses of the 16S rRNA gene sequence indicated that the organism was a member of the domain Bacteria and formed a deep branch within the phylum Aquificae, with Thermovibrio ruber as its closest relative (94·4 % sequence similarity). On the basis of phylogenetic, physiological and genetic considerations, it is proposed that the organism represents a novel species within the newly described genus Thermovibrio. The type strain is Thermovibrio ammonificans HB-1T (=DSM 15698T=JCM 12110T).

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 strictly aerobic, Gram-negative, gliding, dull-orange-pigmented, rod-shaped bacterium, designated strain Shu-F-UV2-2T, was isolated from sediment (Carp Island, Republic of Palau) and was the focus of a polyphasic taxonomic study. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated to the family ‘Flammeovirgaceae’ of the phylum Bacteroidetes and that it showed highest sequence similarity (85.5 %) to Flammeovirga yaeyamensis NBRC 100898T. The novel isolate could be differentiated phenotypically and physiologically from recognized members of the family ‘Flammeovirgaceae’. The G+C content of the DNA was 43.0 mol%, MK-7 was the major menaquinone and iso-C15 : 0, C16 : 1 ω7c and C16 : 1 ω5c were the major fatty acids. On the basis of this polyphasic evidence, it was concluded that strain Shu-F-UV2-2T represents a novel species in a new genus of the family ‘Flammeovirgaceae’, for which the name Perexilibacter aurantiacus gen. nov., sp. nov. is proposed. The type strain is Shu-F-UV2-2T (=MBIC06993T=IAM 15413T=KCTC 12867T).

A novel actinomycete, strain SST-8T, was isolated from sand sediment of Samyang Beach in Jeju, Korea, and subjected to a polyphasic taxonomic study. The organism, which produced opaque, circular, yellow colonies, with a coryneform morphology, showed the following chemotaxonomic characteristics: meso-diaminopimelic acid as the diamino acid in the peptidoglycan, MK-8(H2) as the major menaquinone, phosphatidylglycerol as the only polar lipid, anteiso-C15 : 0 and anteiso-C17 : 0 as major fatty acids and a DNA G+C content of 70.7 mol%. The combination of morphological and chemotaxonomic features supported its classification in the genus Brevibacterium. Phylogenetic analyses, based on 16S rRNA gene sequence studies, showed that strain SST-8T formed an intermediate branch between the Brevibacterium luteolum/Brevibacterium otitidis and Brevibacterium mcbrellneri/Brevibacterium paucivorans clusters. Sequence similarity calculations based on a neighbour-joining analysis revealed that the closest relatives of strain SST-8T were the type strains of B. paucivorans (96.6 %), B. luteolum (96.5 %), B. mcbrellneri (96.3 %), Brevibacterium avium (96.0 %) and B. otitidis (95.9 %). Based on a broad set of phenotypic and genetic data, it was evident that the strain represents a novel species of the genus Brevibacterium. The name Brevibacterium samyangense sp. nov. is proposed, with SST-8T (=NRRL B-41420T=KCCM 42316T) as the type strain.

In 2001, a Gram-variable, facultatively anaerobic, endospore-forming bacterium isolated from biodeteriorated mural paintings in the Servilia tomb of the Roman necropolis of Carmona was deposited as Paenibacillus strain LMG 19508. Subsequently, the strain was characterized in detail using phenotypic and molecular methods. The 16S rRNA gene sequence confirmed that the strain belongs to the genus Paenibacillus and indicated its relationship to Paenibacillus mendelii CCM 4839T (96.7 % sequence similarity). The predominant menaquinone was MK-7. The cell wall contained meso-diaminopimelic acid of the A1γ type. The DNA G+C content (50 mol%) and the major fatty acid (anteiso-C15 : 0) of strain LMG 19508T were also consistent with its affiliation to the genus Paenibacillus. DNA–DNA hybridization distinguished strain LMG 19508T from other phylogenetically related Paenibacillus species. Therefore, the isolate represents a novel species, for which the name Paenibacillus sepulcri sp. nov. is proposed. The type strain is CCM 7311T (=LMG 19508T).
