An obligately anaerobic, Gram-stain-negative, spore-forming, short rod-shaped bacterium, designated strain YH- T4B42T, was isolated from the large intestine of a mini-pig. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belongs to the genus Clostridium and is most closely related to Clostridium aminophilum KCTC 5424T, Clostridium symbiosum KCTC 15329T and Clostridium butyricum KCTC 1871T, with 95.5, 92.4 and 83.0 % sequence similarity, respectively. The average nucleotide identity values for strain YH-T4B42T and the closest related strains were lower than 72 %. The G+C content of the isolate was 55.8 mol%. The cell-wall peptidoglycan was A1γ type and contained meso-diaminopimelic acid. The predominant fatty acids were C16 : 0, C18 : 1 cis 9, C14 : 0 and C18 : 0. The major end products of glucose fermentation were lactate, formate and acetate, with a minor amount of butyrate. Based on its phenotypic, phylogenetic and chemotaxonomic properties, a novel species, Clostridium vitabionis sp. nov., is proposed for strain YH-T4B42T (=KCTC 25105T=NBRC 114767T).

A novel Gram-stain-negative, aerobic and rod-shaped halophilic archaeon, designated HD8-45T, was isolated from the red brine of salted brown alga Laminaria produced at Dalian, PR China. According to the results of 16S rRNA gene and rpoB′ gene sequence comparisons, strain HD8-45T showed the highest sequence similarity to the corresponding genes of Salinirussus salinus YGH44T (95.1 and 85.2 % similarities, respectively), Halovenus aranensis EB27T (91.2 and 86.0 % similarities, respectively). The low sequence similarity and the phylogeny implied the novel generic status of strain HD8-45T. Genomic relatedness analyses showed that strain HD8-45T were clearly distinguished from other species in the order Halobacteriales , with average nucleotide identity, amino acid identity and in silico DNA–DNA hybridization values not more than 75.1, 65.6 and 21.5 %. The polar lipid pattern contained phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, two major glycolipids and two minor glycolipids. The two major glycolipids and a minor glycolipid were chromatographically identical to disulfated mannosyl glucosyl diether, sulfated mannosyl glucosyl diether and mannosyl glucosyl diether, respectively. The major respiratory quinones were menaquinone MK-8 and MK-8(H2). The DNA G+C content was 62.0 mol% (Tm ) and 61.9 mol% (genome). All these results showed that strain HD8-45T represents a novel species of a new genus in the order Halobacteriales , for which the name Salinibaculum litoreum gen. nov., sp. nov. is proposed. The type strain of Salinibaculum litoreum is HD8-45T (=CGMCC 1.15328T=JCM 31107T).

Strain VN07A0015T was isolated from soil collected on Cat Ba Island, Vietnam. The taxonomic position of strain VN07A0015T was near Streptomyces aomiensis M24DS4T (98.5 % 16S rRNA gene sequence similarity) and Streptomyces scabrisporus NBRC 100760T (95.6 %), and it clustered within them; however, this cluster was distant from the type strains of other species of the genus Streptomyces . The aerial mycelia of strain VN07A0015T were greyish and formed imperfect spiral spore chains (retinaculiaperti type) with smooth-surfaced spores. The morphological features of strain VN07A0015T were different from those of the type strains of S. aomiensis and S. scabrisporus . The chemotaxonomic characteristics of strain VN07A0015T were typical for all members of the genus Streptomyces , which possessed ll-type diaminopimelic acid, menaquinone MK-9(H6, H8) and the major fatty acids iso-C16 : 0 and iso-C15 : 0. DNA–DNA relatedness between strain VN07A0015T and S. aomiensis NBRC 106164T was less than 30 %. In addition, some physiological and biochemical traits differed from those of S. aomiensis . Therefore, we propose that strain VN07A0015T be classified in the genus Streptomyces as a representative of Streptomyces catbensis sp. nov. (type strain VN07A0015T = VTCC-A-1889T = NBRC 107860T).

Two Gram-stain-positive, non-endospore-forming actinobacteria (Ca8Tand Ca14) were isolated from a bioreactor with extensive phosphorus removal. Based on 16S rRNA gene sequence similarity comparisons, strains Ca8T and Ca14 were shown to belong to the genus Gordonia and were most closely related to Gordonia hirsuta DSM 44140T (98.0 % sequence similarity) and Gordonia hydrophobica DSM 44015T (97.2 %). In comparison with the sequences of the type strains of all other species of the genus Gordonia tested, similarities were below 97 %. The quinone systems of the strains were determined to consist predominantly of MK-9H2. The polar lipid profile for both organisms consisted of diphosphatidylglycerol, phosphatidylglycerol, phospatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. Whole-organism hydrolysates contained meso-diaminopimelic acid as the diamino acid of the peptidoglycan; mycolic acids were detected as well. These chemotaxonomic traits and the major fatty acids, which were C16 : 1 cis-9, C16 : 0 and C18 : 1 and tuberculostearic acid strongly supported the grouping of strains Ca8T and Ca14 into the genus Gordonia . The two strains showed a DNA–DNA similarity of 96 %. DNA–DNA hybridizations of strain Ca8T with G. hirsuta DSM 44140T and G. hydrophobica DSM 44015T resulted in values of 26.3 and 25.0 %, respectively. These results and those of the physiological and biochemical tests allowed a clear phenotypic differentiation of strains Ca8T and Ca14 from the most closely related species of the genus Gordonia . It is concluded that strains Ca8T and Ca14 represent a novel species, for which the name Gordonia phosphorivorans sp. nov. is proposed, with the type strain Ca8T ( = DSM 45630T = CCUG 61533T = CCM 7957T = LMG 26648T).
