A bacterial strain, UDC377T, was isolated from seawater samples collected at Seo-do on the coast of Dokdo island in the East Sea, and was subjected to taxonomic study using a polyphasic approach. Strain UDC377T was pale-yellow, Gram-staining-negative, non-motile, rod-shaped and aerobic. The strain grew optimally at 25–28 °C, in the presence of 2 % (w/v) NaCl and at pH 7.0–7.5. Strain UDC377T produced carotenoid pigments; however, it did not produce flexirubin-type pigments. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain UDC377T clustered with members of the genus Lutibacter and appeared most closely related to Lutibacter agarilyticus KYW566T (96.0 % 16S rRNA gene sequence similarity) followed by L. aestuarii MA-My1T (95.0 %), L. litoralis CL-TF09T (94.9 %), L. maritimus S7-2T (94.1 %) and L. flavus IMCC1507T (94.0 %). The DNA G+C content of strain UDC377T was 30.8 mol%. Strain UDC377T contained MK-6 as the predominant menaquinone, iso-C15 : 0 3-OH, iso-C15 : 0 and iso-C16 : 0 3-OH as the major fatty acids, and phosphatidylethanolamine, two unknown aminolipids and six unknown lipids as the major polar lipids. Based on phenotypic properties and phylogenetic data presented, strain UDC377T is considered to represent a novel species of the genus Lutibacter , for which the name Lutibacter oricola sp. nov. is proposed.

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 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).
