The menaquinones were identified as MK-9(H₈), MK-9(H₆) and MK-9(H₄). The phospholipid profile was found to consist of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, an unidentified phospholipid and an unidentified lipid. The major fatty acids were identified as anteiso-C_15:0, iso-C_16:0, C_16:0 and C_15:0. However, multilocus sequence analysis based on five house-keeping genes (atpD, gyrB, rpoB, recA and trpB), low DNA-DNA hybridization results and some phenotypic, physiological and biochemical properties could differentiate the strain from its close relatives in the genus Streptomyces. Therefore, strain NEAU-QTH3-11^T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces lutosisoli sp. nov. is proposed, with NEAU-QTH3-11^T (=DSM 42165^T=CGMCC 4.7198^T) as the type strain.

The predominant fatty acids were iso-C_15:0, iso-C_16:0, iso-C_14:0, and anteiso-C_15:0, as in the case of genus Terrabacter, thereby supporting the categorization of strain Gsoil 653^T. However, the DNA-DNA relatedness between Gsoil 653^T and closely related strains of Terrabacter species was low at less than 31%. Moreover, strain Gsoil 653^T could be both genotypically and phenotypically distinguished from the recognized species of the genus Terrabacter. This isolate, therefore, represents a novel species, for which the name Terrabacter ginsengisoli sp. nov. is proposed with the type strain Gsoil 653^T (= KACC 19444^T = LMG 30325^T).

The major fatty acids in strain TRM 49605^T were identified as iso C_16:0, anteiso C_15:0, C_16:0 and Summed Feature 5 as defined by MIDI. The main menaquinones were identified as MK-9(H₄), MK-9(H₆), MK-9(H₈) and MK-10(H₆). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. The G+C content of the genomic DNA was determined to be 71.2 %. The DNA–DNA relatedness between strain TRM 49605^T and the phylogenetically related strain S. roseolilacinus NBRC 12815^T was 60.12 ± 0.06 %, which is lower than the 70 % threshold value for delineation of genomic prokaryotic species. Based on the phenotypic, chemotaxonomic and phylogenetic data, strain TRM 49605^T (=CCTCC AA2015026^T = KCTC 39666^T) should be designated as the type strain of a novel species of the genus Streptomyces, for which the name Streptomyces luozhongensis sp. nov. is proposed.     

<Emphasis Type="Italic">Streptomyces tunisialbus</Emphasis> sp. nov., a novel <Emphasis Type="Italic">Streptomyces</Emphasis> species with antimicrobial activity

A novel actinomycete strain designated S2^T was isolated from Tunisian rhizosphere soil of Lavandula officinalis. This isolate exhibited broad spectrum antibacterial activity against several Gram-positive and Gram-negative bacteria and also antifungal activity against yeast and filamentous fungi. The isolate S2^T presents morphological and chemotaxonomic characteristics typical of the members of the genus Streptomyces. Whole cell hydrolysates of S2^T were found to contain LL-diaminopimelic acid. The major fatty acids were identified as C16:0, anteiso-C15:0 and iso-C16:0 whereas the predominant menaquinones were found to be MK-9(H6) and MK-9(H8). The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and three unidentified compounds. The G+C content of the genomic DNA was determined to be 71.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2^T belongs to the genus Streptomyces and is closely related to Streptomyces netropsis DSM 40259^T with 99.86% sequence similarity. Multi-locus sequence analysis (MLSA) based on four house-keeping gene alleles (gyrB, recA, trpB, rpoB) showed that isolate S2^T is closely related to S. netropsis, with an MLSA distance greater than 0.007. The DNA–DNA relatedness between strain S2^T and its near phylogenetic neighbour was 63.6 ± 2.3%, which is lower than the 70% threshold value for delineation of genomic prokaryotic species. This isolate was also distinguished from the type strain S. netropsis DSM 40259^T, using a combination of morphological and physiological features. Based on its phenotypic and molecular properties, strain S2^T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces tunisialbus sp. nov. is proposed. The type strain is S2^T (= JCM 32165^T = DSM 105760^T).     

<Emphasis Type="Italic">Edaphorhabdus rosea</Emphasis> gen. nov., sp. nov., a new member of the family <Emphasis Type="Italic">Cytophagaceae</Emphasis> isolated from soil in South Korea

A Gram-stain negative, aerobic, oxidase and catalase positive, non-flagellated, pink coloured bacterium with gliding motility, designated as strain UDD1^T was isolated from soil. The bacterium lacked flexirubin-type pigments. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain UDD1^T formed a lineage within the family Cytophagaceae of the phylum Bacteroidetes, and forms a distinct clade with type strains of the closely related genus Pontibacter with similarities of 91.36–93.62%. Strain UDD1^T contained MK-7 as the predominant menaquinone and summed feature 4 (iso-C_17:1 I and/or anteiso-C_17:1 B) and iso-C_15:0 as the major fatty acids. The major polar lipids were phosphatidylethanolamine and an unidentified glycolipid. The DNA G+C content of strain UDD1^T was 49 mol%. On the basis of phenotypic, genotypic and phylogenetic analyses, the strain UDD1^T represents a novel species of a new genus in the family Cytophagaceae, for which the name Edaphorhabdus rosea gen. nov., sp. nov., is proposed. The type strain of Edaphorhabdus rosea is UDD1^T (=?KCTC 62117^T =?JCM 32366^T). The Digital Protologue Database Taxon number for strain UDD1^T is GA00058.     

<Emphasis Type="Italic">Pedobacter aquicola</Emphasis> sp. nov., isolated from freshwater

A non-motile, pink-pigmented bacterial strain designated IMCC25679^T, was isolated from freshwater Lake Chungju of Korea. Phylogenetic trees based on 16S rRNA gene sequences showed that the strain IMCC25679^T formed a lineage within the genus Pedobacter. The strain IMCC25679^T was closely related to Pedobacter daechungensis Dae 13^T (96.4% sequence similarity), Pedobacter rivuli HME8457^T (95.3%) and Pedobacter lentus DS-40^T (94.3%). The major fatty acids of IMCC- 25679^T were iso-C_15:0, iso-C_16:0 and summed feature 3 (comprising C_16:1ω6c and/or C_16:1ω7c). The major respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine (PE), an unidentified sphingolipid (SL), an unidentified aminolipid (AL) and three unidentified polar lipids (PL). The DNA G + C content of IMCC25679^T was 32.2 mol%. Based on the evidence presented in this study, the strain IMCC25679^T represents a novel species within the genus Pedobacter, with the proposed name Pedobacter aquicola, sp. nov. The type strain is IMCC25679^T (= KACC 19486^T = NBRC113131^T).
