A Gram-negative, non-motile, non-spore-forming bacterial strain, PR1T, was isolated from a mud core sample containing colonial choanoflagellates near Hog Island, Virginia, USA. Strain PR1T grew optimally at 30 °C and with 3 % (w/v) NaCl. Strain PR1T contained MK-7 as the major menaquinone as well as carotenoids but lacked pigments of the flexirubin-type. The predominant fatty acids were iso-C15 : 0 (29.4 %), iso-C17 : 1ω9c (18.5 %) and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 11.3 %). The major polar lipids detected in strain PR1T were phosphatidylethanolamine, an unknown phospholipid, an aminophospholipid, an aminolipid and two lipids of unknown character. The DNA G+C content was 38.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain PR1T fell within the cluster comprising the genus Algoriphagus and was most closely related to Algoriphagus halophilus JC 2051T (95.4 % sequence similarity) and Algoriphagus lutimaris S1-3T (95.3 % sequence similarity). The 16S rRNA gene sequence similarity between strain PR1T and the type strains of other species of the genus Algoriphagus were in the range 91–95 %. Differential phenotypic properties and phylogenetic and genetic distinctiveness of strain PR1T demonstrated that this strain was distinct from other members of the genus Algoriphagus , including its closest relative, A. halophilus . Based on phenotypic, chemotaxonomic, phylogenetic and genomic data, strain PR1T should be placed in the genus Algoriphagus as a representative of a novel species, for which the name Algoriphagus machipongonensis sp. nov. is proposed. The type strain is PR1T ( = ATCC BAA-2233T  = DSM 24695T).

Strain SB026T was isolated from Brazilian rainforest soil and its taxonomic position established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological features consistent with its classification in the genus Amycolatopsis and formed a branch in the Amycolatopsis 16S rRNA gene tree together with Amycolatopsis bullii NRRL B-24847T, Amycolatopsis plumensis NRRL B-24324T, Amycolatopsis tolypomycina DSM 44544T and Amycolatopsis vancoresmycina NRRL B-24208T. It was related most closely to A. bullii NRRL B-24847T (99.0 % 16S rRNA gene sequence similarity), but was distinguished from this strain by a low level of DNA–DNA relatedness (~46 %) and discriminatory phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the isolate should be classified in the genus Amycolatopsis as representing a novel species, Amycolatopsis rhabdoformis sp. nov. The type strain is SB026T ( = CBMAI 1694T = CMAA 1285T = NCIMB 14900T).

A novel Gram-negative, aerobic, catalase- and oxidase-positive, non-sporulating, non-motile, rod-shaped bacterium, designated strain UST081027-248T, was isolated from seawater of the Red Sea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain UST081027-248T fell within the genus Erythrobacter . Levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of Erythrobacter species ranged from 95.3 % (with Erythrobacter gangjinensis ) to 98.2 % (with Erythrobacter citreus ). However, levels of DNA–DNA relatedness between strain UST081027-248T and the type strains of closely related species were below 70 %. Optimal growth of the isolate occurred in the presence of 2.0 % NaCl, at pH 8.0–9.0 and at 28–36 °C. The isolate did not produce bacteriochlorophyll a. The predominant cellular fatty acids were C17 : 1ω6c, summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) and C15 : 0 2-OH. The genomic DNA G+C content of strain UST081027-248T was 60.4 mol%. Phenotypic properties and phylogenetic distinctiveness clearly indicated that strain UST081027-248T represents a novel species of the genus Erythrobacter , for which the name Erythrobacter pelagi sp. nov. is proposed. The type strain is UST081027-248T ( = JCM 17468T = NRRL 59511T).

A Gram-positive rod, designated 01-Gi-001T, was isolated from a wall colonized with moulds. The 16S rRNA gene sequence analysis clearly showed that the isolate belonged to the genus Microbacterium . On the basis of pairwise comparisons of 16S rRNA gene sequences, strain 01-Gi-001T was most closely related to Microbacterium hydrocarbonoxydans DSM 16089T (98.9 % sequence similarity), Microbacterium profundi Shh49T (98.7 %), Microbacterium phyllosphaerae DSM 13468T (98.3 %) and Microbacterium foliorum DSM 12966T (98.1 %). The diagnostic diamino acid of the peptidoglycan was ornithine. The major menaquinones detected were MK-13 and MK-12. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, one unknown phospholipid and one unknown glycolipid. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0, which were in agreement with those reported for other members of the genus Microbacterium . Physiological and biochemical characteristics and DNA–DNA relatedness between strain 01-Gi-001T and the type strains of its closest phylogenetic neighbours showed clear differences. For this reason, strain 01-Gi-001T ( = DSM 22178T = CCM 7640T) is proposed as the type strain of a novel species, Microbacterium murale sp. nov.

A Gram-stain-negative, non-motile, ovoid or rod-shaped bacterial strain, designated L-6T, was isolated from seawater of Baekdo harbour of the East Sea in Korea and its taxonomic position was investigated by using a polyphasic study. Strain L-6T grew optimally at 30 °C, at pH 7.5–8.0 and in the presence of 2 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain L-6T formed a cluster with the type strain of Celeribacter neptunius at a bootstrap resampling value of 100 %. Strain L-6T exhibited 16S rRNA gene sequence similarity values of 97.7 % to C. neptunius H 14T and of less than 96.2 % to the type strains of other species used in the phylogenetic analysis. The G+C content of the chromosomal DNA of strain L-6T was 60.9 mol%. The predominant ubiquinone found in strain L-6T and C. neptunius CIP 109922T was ubiquinone-10 (Q-10). The predominant fatty acid of strain L-6T and C. neptunius CIP 109922T was C18 : 1ω7c. The major polar lipids of strain L-6T were phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid. The mean level of DNA–DNA relatedness between strain L-6T and C. neptunius CIP 109922T was 17 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, demonstrated that strain L-6T is distinguishable from C. neptunius . On the basis of the data presented, strain L-6T is considered to represent a novel species of the genus Celeribacter , for which the name Celeribacter baekdonensis sp. nov. is proposed.

A Gram-stain-negative, aerobic, motile with one polar flagellum γ-proteobacterium, designated strain SBZ3-12T, was isolated from surfaces of weathered potassic trachyte. Phylogenetic analysis of this strain based on 16S rRNA gene sequences showed that it was most closely related to Dyella japonica XD53T (97.9 % 16S rRNA gene sequence similarity), Dyella terrae JS14-6T (97.7 %), Dyella soli JS12-10T (97.5 %) and Dyella koreensis BB4T (97.0 %). The DNA G+C content of strain SBZ3-12T was 64.0 mol%. In addition, iso-C17 : 1ω9c, iso-C15 : 0 and iso-C16 : 0 were the major cellular fatty acids and ubiquinone Q-8 was the predominant respiratory quinone. The low DNA–DNA relatedness values between strain SBZ3-12T and recognized species of the genus Dyella and the many phenotypic properties supported the classification of strain SBZ3-12T as a representative of a novel species of the genus Dyella , for which the name Dyella jiangningensis sp. nov. is proposed. The type strain is SBZ3-12T ( = CCTCC AB 2012160T = KACC 16539T = DSM 26119T).

A Gram-stain-positive, strictly aerobic, spherical, non-motile red-pigmented bacterial strain, designated MJ27T, was isolated from a sludge sample of the Daejeon sewage disposal plant in South Korea. A polyphasic approach was used to study the taxonomic position of strain MJ27T. Strain MJ27T shared highest 16S rRNA gene sequence similarity with Deinococcus grandis DSM 3963T (98.8 %), Deinococcus caeni Ho-08T (97.5 %) and Deinococcus aquaticus PB314T (96.6 %.); levels of sequence similarity with the type strains of other Deinococcus species were less than 96.0 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ27T belonged to the clade formed by members of the genus Deinococcus in the family Deinococcaceae . The G+C content of the genomic DNA of strain MJ27T was 67.6 mol%. The chemotaxonomic characteristics of strain MJ27T were typical of members of the genus Deinococcus , with MK-8 as the predominant respiratory quinone, C16 : 1ω7c, C15 : 1ω6c, C16 : 0 and C15 : 0 as major fatty acids (>12 %), ornithine as the diamino acid in the cell-wall peptidoglycan and resistance to gamma radiation [D10 (dose required to reduce the bacterial population by tenfold) >9 kGy]. The low levels of DNA–DNA relatedness reported here (5.3±1.5–29.2±2.3 %) indicate that strain MJ27T represents a species that is separate from its closest relatives in the genus Deinococcus . On the basis of phylogenetic inference, fatty acid profile and other phenotypic properties, strain MJ27T is considered to represent a novel species of the genus Deinococcus , for which the name Deinococcus daejeonensis sp. nov. is proposed. The type strain is MJ27T ( = KCTC 13751T = JCM 16918T).

A Gram-negative, motile, ovoid- to rod-shaped bacterial strain, designated MA1-10T, was isolated from a sea squirt (Halocynthia roretzi) collected from the South Sea, Korea. Strain MA1-10T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain MA1-10T clustered with Roseovarius crassostreae CV919-312T, with which it exhibited 97.1 % sequence similarity, at a bootstrap resampling value of 96.2 %. It exhibited 93.3–95.8 % 16S rRNA gene sequence similarity to the type strains of other recognized Roseovarius species. Strain MA1-10T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid, which is consistent with data for the genus Roseovarius . The major polar lipids were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and an unidentified lipid. The DNA G+C content of strain MA1-10T was 55.4 mol%. Mean DNA–DNA relatedness between strain MA1-10T and R. crassostreae DSM 16950T was 13 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, demonstrated that strain MA1-10T could be distinguished from all recognized Roseovarius species. On the basis of the data presented, strain MA1-10T is considered to represent a novel species of the genus Roseovarius , for which the name Roseovarius halocynthiae sp. nov. is proposed; the type strain is MA1-10T ( = KCTC 23462T = CCUG 60745T).
