A lactic acid bacterium, strain CCTCC M 2011381T, isolated from the brine of the traditional Chinese snack, stinky tofu, was studied to determine its taxonomic position. It was a Gram-stain-positive, non-motile, facultatively anaerobic rod-shaped bacterium that did not exhibit catalase activity. The DNA G+C content of the strain was 44.1 % and its peptidoglycan was characterized by the presence of meso-diaminopimelic acid. Levels of 16S rRNA gene sequence similarity between strain CCTCC M 2011381T and the most closely related species Lactobacillus senioris JCM 17472T, Lactobacillus parafarraginis JCM 14109T and Lactobacillus diolivorans JCM 12183T were 96.5, 96.4 and 96.4 %, respectively. Combined with data from high-resolution genomic markers recA, rpoA and pheS, strain CCTCC M 2011381T was classified as representing a novel species. The strain could also be distinguished from other related species of the genus Lactobacillus by its physiological and biochemical characteristics. Based on the phylogenetic, physiological and biochemical data, it is proposed that the new isolate can be classified as representing a novel species of the genus Lactobacillus , for which the name Lactobacillus curieae sp. nov. (type strain CCTCC M 2011381T = S1L19T = JCM 18524T) is proposed.

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-negative, non-fermentative bacterial strains, designated 11-0202T and 11-0607, were isolated from soil in South Korea, and four others, LUH 13522, LUH 8638, LUH 10268 and LUH 10288, were isolated from a beet field in Germany, soil in the Netherlands, and sediment of integrated fish farms in Malaysia and Thailand, respectively. Based on 16S rRNA, rpoB and gyrB gene sequences, they are considered to represent a novel species of the genus Acinetobacter . Their 16S rRNA gene sequences showed greatest pairwise similarity to Acinetobacter beijerinckii NIPH 838T (97.9–98.4 %). They shared highest rpoB and gyrB gene sequence similarity with Acinetobacter johnsonii DSM 6963T and Acinetobacter bouvetii 4B02T (85.4–87.6 and 78.1–82.7 %, respectively). Strain 11-0202T displayed low DNA–DNA reassociation values (<40 %) with the most closely related species of the genus Acinetobacter . The six strains utilized azelate, 2,3-butanediol, ethanol and dl-lactate as sole carbon sources. Cellular fatty acid analyses showed similarities to profiles of related species of the genus Acinetobacter : summed feature 3 (C16 : 1ω7c, C16 : 1ω6c; 24.3–27.2 %), C18 : 1ω9c (19.9–22.1 %), C16 : 0 (15.2–22.0 %) and C12 : 0 (9.2–14.2 %). On the basis of the current findings, it is concluded that the six strains represent a novel species, for which the name Acinetobacter kookii sp. nov. is proposed. The type strain is 11-0202T ( = KCTC 32033T = JCM 18512T).

A Gram-stain-positive bacterial isolate, designated LMM-1652T, was isolated from an intrauterine cytobrush sample originating from a postpartum Holstein Friesian dairy cow. The strain had a rod to coccoid-shape, was catalase-positive and oxidase-negative. 16S rRNA gene sequence similarity analyses revealed that its closest relatives were Corynebacterium falsenii (97.05 % similarity), Corynebacterium jeikeium (96.83 %) and Corynebacterium urealyticum (96.82 %). Subsequent whole genome analysis showed that the genome-to-genome distance of strain LMM-1652T to its closest relatives was in the range of 23.2–24.8 %, while the average nucleotide identity values ranged from 73.7 to 74.3%, thus confirming that this isolate represents a novel species. Strain LMM-1652T was characterized by a quinone system mainly consisting of MK-9(H2) and MK-10(H2). The polar lipids profile of the strain consisted mainly of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol-mannoside, as well as one unidentified lipid lacking any functional group. Smaller amounts of four unidentified phospholipids, four unidentified glycolipids, β-gentiobiosyl diacylglycerol and four unidentified lipids lacking a functional group were also found. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid of the peptidoglycan. The fatty acid profile was mainly composed of C18 : 1 ω9c, C18 : 0 and C16 : 0. We propose a novel species of the genus Corynebacterium with the name Corynebacterium urogenitale LMM-1652T (=LMG 31163T=DSM 108747T).

China is a hotspot for hot springs and during microbial diversity analysis of Tengchong hot spring, Yunnan province, south-west PR China, two strains designated SYSU G01001T and SY-13 were isolated. SYSU G01001T and SY-13 were Gram-stain-positive, motile and spore-forming. Colonies were white, circular, raised and punctiform. SYSU G01001T and SY-13 grew at pH 6.0–9.0 (optimum pH 8.0) and at 23–37 °C (optimum 28 °C). The 16S rRNA gene sequence similarity between SYSU G01001T and SY-13 was 99.6 % but these strains shared low sequence similarity with Paenibacillus azotifigens (97.5 %) indicating that they represented a novel species. On the basis of the results, SYSU G01001T was selected for further investigations and SY-13 was considered to represent a second strain of the species. The cell wall peptidoglycan of SYSU G01001T was meso-2,6-diaminopimelic acid and MK-7 was the only respiratory quinone. The polar lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), two unidentified aminolipids (AL), two unidentified amino phospholipids (APL), an unidentified phospholipid (PL) and an unidentified polar lipid (L). The G+C content of the genomic DNA was 53.9 mol%. The average nucleotide identity (ANIb and ANIm) values between SYSU G01001T and Paenibacillus azotifigens LMG 29963T were below the cut-off level (95–96 %) recommended as the average nucleotide identity (ANI) criterion for interspecies identity. On the basis of the above results strain SYSU G01001T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus tepidiphilus sp. nov. is proposed. The type strain is SYSU G01001T (=KCTC 33952T=CGMCC 1.13870T).

A novel actinobacterial strain, designated, NIO-1009T, was isolated from a marine sediment sample collected from Chorao Island, Goa, India. Phylogenetic analysis comparisons based on 16S rRNA gene sequences between strain NIO-1009T and other members of the genus Rhodococcus revealed that strain NIO-1009T had the closest sequence similarity to Rhodococcus kroppenstedtii DSM 44908T and Rhodococcus corynebacterioides DSM 20151T with 99.2 and 99.1 %, respectively. Furthermore, DNA–DNA hybridization results showed that R. kroppenstedtii DSM 44908T and R. corynebacterioides DSM 20151T were 39.5 (3.0 %) and 41.7 (2.0 %) with strain NIO-1009T, respectively, which were well below the 70 % limit for any novel species proposal. Phylogenetically strain NIO-1009T forms a stable clade with and R. kroppenstedtii DSM 44908T and R. corynebacterioides DSM 20151T with 100 % bootstrap values. Strain NIO-1009T contained meso-diaminopimelic acid as the diagnostic diamino acid and galactose and arabinose as the cell wall sugars. The major fatty acids were C16 : 0, C18 : 1ω9c, C16 : 1(ω6c and/or ω7c) and 10-methyl C18 : 0. The only menaquinone detected was MK-8(H2), while the major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and one unknown phospholipid. The G+C content of the genomic DNA was 66.9 mol%. The phenotypic and genotypic data showed that strain NIO-1009T warrants recognition as a novel species of the genus Rhodococcus for which the name Rhodococcus enclensis sp. nov., is proposed; the type strain is NIO-1009T ( = NCIM 5452T = DSM 45688T).

A facultatively anaerobic, Gram-stain-positive, rod-shaped bacterium, designated strain KB0549T, was isolated from sesame oil cake. Cells were motile, round-ended rods, and produced central or terminal spores. The cell wall peptidoglycan contained meso-diaminopimelic acid as the diamino acid. The major fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0. The DNA G+C content of strain KB0549T was 51.9 mol%. On the basis of 16S rRNA gene sequence phylogeny, strain KB0549T was affiliated with the genus Paenibacillus in the phylum Firmicutes and was most closely related to Paenibacillus cookii with 97.4 % sequence similarity. Strain KB0549T was physiologically differentiated from P. cookii by the high content of anteiso-C17 : 0, inability to grow at 50 °C, spore position, and negative Voges–Proskauer reaction. Based on these unique physiological and phylogenetic characteristics, it is proposed that the isolate represents a novel species, Paenibacillus relictisesami sp. nov.; the type strain is KB0549T ( = JCM 18068T = DSM 25385T).

A Gram-stain-negative, oxidase-positive, catalase-positive, aerobic, orange-pigmented, rod-shaped and non-motile bacterium designated strain MMS17-SY002T was isolated from island soil. The isolate grew at 20–37 °C (optimum, 30 °C), at pH 6.0–9.5 (optimum, pH 7) and in the presence of 0.5–4.0 % (w/v) NaCl (optimum, 2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MMS17-SY002T was mostly related to the genus Muriicola of the family Flavobacteriaceae and had highest sequence similarity of 96.82 % to Muriicola marianensis A6B8T and Muriicola jejuensis EM44T, but formed a distinct phylogenetic line within the genus. Chemotaxonomic analyses showed that menaquinone 6 was the predominant isoprenoid quinone, the major fatty acids were iso-C15 : 1 G and iso-C15 : 0, and the diagnostic polar lipid was phosphatidylethanolamine. The genomic DNA G+C content was 42.4 mol%. Strain MMS17-SY002T could be distinguished from related species by the combination of trypsin, α-chymotrypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase, α-galactosidase, β-galactosidase and β-glucosidase activities. The orthologous average nucleotide identity between the genomes of strain MMS17-SY002T and M. jejuensis and that between the strain and M. marianensis A6B8T were 73.26 and 73.33%, respectively, thus confirming the separation of the strain from related species at species level. Based on the phenotypic, phylogenetic, chemotaxonomic and genomic characterization, MMS17-SY002T should be recognized as a novel species of the genus Muriicola , for which the name Muriicola soli sp. nov. is proposed. The type strain is MMS17-SY002T (=KCTC 62790T=JCM 32370T).
