A Gram-stain-positive, aerobic, rod-shaped, yellow actinobacterium, designated MNA2T, was isolated from a hexachlorocyclohexane-contaminated soil in North India. Strain MNA2T showed 95 % 16S rRNA gene sequence similarity with Microbacterium halotolerans YIM 70130T. Phylogenetic analysis of 16S rRNA gene sequences showed that strain MNA2T belonged to a clade represented by the genus Microbacterium of the family Microbacteriaceae. Strain MNA2T contained anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0 as the predominant fatty acids and diphosphatidylglycerol, phosphatidylglycerol and two unknown polar lipids. The menaquinones were MK-12, MK-11, MK-13 and MK-10, in an approximate molar ratio of 45 : 40 : 13 : 3, respectively. The DNA G+C content was 65.3 mol%. The peptidoglycan was of the B type of cross-linkage with ornithine as the diagnostic diamino acid. The results of the phylogenetic, phenotypic and chemotaxonomic analysis indicate that strain MNA2T belongs to a previously unrecognized species of the genus Microbacterium, for which the name Microbacterium lindanitolerans sp. nov. is proposed. The type strain is MNA2T (=DSM 22422T =CCM 7585T).

A novel Gram-positive bacterium, strain 40T, was isolated in the course of identifying bacteria from infective juveniles of the entomopathogenic nematode Steinernema thermophilum. Based on 16S rRNA gene analysis, strain 40T was found to be related to the type strains of recognized species of the genus Leucobacter, family Microbacteriaceae. The 16S rRNA gene sequence similarity values of strain 40T and Leucobacter albus IAM 14851T, Leucobacter luti LMG 23118T, Leucobacter alluvii LMG 23117T, Leucobacter komagatae DSM 8803T, Leucobacter chromiireducens CIP 108389T and Leucobacter aridicollis CIP 108388T, respectively, were 97.3, 97.5, 97.6, 97.6, 97.6 and 98.5 %. Chemotaxonomic analysis also supported the affiliation of strain 40T to the genus Leucobacter: the major menaquinone was MK-11, the peptidoglycan cross-linkage was of the B-type, the cell wall diamino acid was l-diaminobutyric acid and the major fatty acids were anteiso-C15 : 0 (42 %), anteiso-C17 : 0 (34 %) and iso-C16 : 0 (16 %). Based upon the biochemical and genomic analyses, strain 40T is sufficiently distinct from the type strains of recognized Leucobacter species to warrant the description of a novel species, for which the name Leucobacter iarius sp. nov. is proposed. The type strain is strain 40T (=DSM 17402T=CIP 108831T).

A novel Gram-stain-positive, aerobic, endospore-forming, rod-shaped bacterial strain YN3T was isolated from ripened Pu'er tea. Phylogenetic analysis of 16S rRNA gene sequences showed that the strain belonged to the family Sporolactobacillaceae and was closely related to Pullulanibacillus naganoensis DSM 10191T (95.8 % 16S rRNA gene sequence similarity) and Pullulanibacillus uraniitolerans DSM 19429T (95.4 %). Growth of the strain was observed at 20–50 °C (optimum 30–37 °C), at pH 4.0–8.0 (optimum pH 5.0–6.0). The strain had a cell-wall type A1γ peptidoglycan with meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinone was menaquinone-7 (MK-7). The major fatty acids were anteiso-C15:0, anteiso-C17:0 and C18:1ω7c. The DNA G+C content of strain YN3T was 38.7 mol%. Strain YN3T could be differentiated from recognized species of the genus Pullulanibacillus based on phenotypic characteristics, chemotaxonomic differences, phylogenetic analysis and DNA–DNA hybridization data. On the basis of polyphasic evidence from this study, Pullulanibacillus pueri sp. nov., is proposed, with strain YN3T ( = CGMCC 1.12777T = JCM 30075T) as the type strain.

The 16S Rrna Gene

A novel actinomycete, designated strain Sco-B14T, was isolated from volcanic ash collected near Darangshi Oreum (a parasitic or satellite volcano) in Jeju, Republic of Korea. The organism formed well-developed, branched substrate mycelium, on which short chains of non-motile spores were arranged singly or in clusters. Aerial mycelium was not produced. Globose bodies were observed. The reverse colour of colonies was light brown to brown. Diffusible pigments were produced on ISP medium 3 and oatmeal-nitrate agar. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Sco-B14T formed a lineage within the family Micromonosporaceae and was distinct from established genera. The 16S rRNA gene sequence similarity of strain Sco-B14T to members of related genera of the family was 95.0–95.7 % to type strains of Catellatospora species, 94.7 % to Hamadaea tsunoensis IMSNU 22005T, 94.7 % to Longispora albida K97-0003T and 94.0 % to Catelliglobosispora koreensis LM 042T. 3-Hydroxydiaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Whole-cell sugars were glucose, rhamnose, ribose, xylose, arabinose, galactose and mannose. The polar lipids included diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The menaquinone profile contained MK-10(H4) (49 %), MK-9(H4) (24 %), MK-10(H6) (18 %) and MK-9(H6) (9 %). The predominant fatty acids were iso-C15 : 0 and C17 : 0. The DNA G+C content was 70.1 mol%. The combination of chemotaxonomic and phylogenetic data clearly separated the isolate from the type strains of all genera in the family Micromonosporaceae. On the basis of the phylogenetic and chemotaxonomic data presented in this paper, strain Sco-B14T is considered to represent a novel species of a new genus in the family Micromonosporaceae, for which the name Allocatelliglobosispora scoriae gen. nov., sp. nov. is proposed. The type strain of Allocatelliglobosispora scoriae is Sco-B14T (=KCTC 19661T =DSM 45362T).

Strain M-SA3-94T, an aerobic, Gram-stain-positive, ovoid- to rod-shaped, non-motile bacterium, was isolated from the marine sediment of Ardley cove, King George Island, Antarctica. Strain M-SA3-94T grew optimally at pH 5.0–6.0, 20 °C and in the presence of 1.0 % (w/v) NaCl. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain M-SA3-94T belonged to the genus Nocardioides in the family Nocardioidaceae, clustering with Nocardioides plantarum NCIMB 12834T, Nocardioides ginsengagri BX5-10T, Nocardioides marinquilinus CL-GY44T and Nocardioides lianchengensis D94-1T (with 96.1 %, 95.9 %, 94.5 % and 94.7 % 16S rRNA gene sequence similarity, respectively). The chemotaxonomic properties of strain M-SA3-94T were similar to those of members of the genus Nocardioides with validly published names. The major fatty acid was iso-C16 : 0. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol and three unknown phospholipids. The diagnostic diamino acid in the cell-wall peptidoglycan was ll-2, 6-diaminopimelic acid. MK-8(H4) was the predominant menaquinone and the DNA G+C content of this strain was 66.7 mol%. On the basis of these phenotypic, phylogenetic and chemotaxonomic data, strain M-SA3-94T represents a novel species of the genus Nocardioides, for which the name Nocardioides antarcticus sp. nov. is proposed. The type strain is M-SA3-94T ( = CCTCC AB2014053T = LMG 28254T).

© 2017 IUMS. A novel anaerobic pectinolytic bacterium (strain 14T) was isolated from human faeces. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 14T belonged to the family Ruminococcaceae, but was located separately from known clostridial clusters within the taxon. The closest cultured relative of strain 14T was Acetivibrio cellulolyticus (89.7% sequence similarity). Strain 14T shared ~99% sequence similarity with cloned 16S rRNA gene sequences from uncultured bacteria derived from the human gut. Cells were Gram-stain-positive, non-motile cocci approximately 0.6μm in diameter. Strain 14T fermented pectins from citrus peel, apple, and kiwifruit as well as carbohydrates that are constituents of pectins and hemicellulose, such as galacturonic acid, xylose, and arabinose. TEM images of strain 14T, cultured in association with plant tissues, suggested extracellular fibrolytic activity associated with the bacterial cells, forming zones of degradation in the pectin-rich regions of middle lamella. Phylogenetic and phenotypic analysis supported the differentiation of strain 14T as a novel genus in the family Ruminococcaceae. The name Monoglobus pectinilyticus gen. nov., sp. nov. is proposed; the type strain is 14T (JCM 31914T=DSM 104782T).

A rod shaped, Gram-stain-negative, chemo-organotrophic, heterotrophic, strictly aerobic, non-gliding bacterium, designated strain PLRT, was isolated from faeces of the mollusc Aplysia punctata (Mollusca, Gastropoda) that had been fed with green algae belonging to the genus Ulva. The novel strain was able to degrade ulvan, a polysaccharide extracted from green algae (Chlorophyta, Ulvophyceae). The taxonomic position of strain PLRT was investigated by using a polyphasic approach. Strain PLRT was dark orange, oxidase-positive, catalase-positive and grew optimally at 25 °C, at pH 7.5 and in the presence of 2.5 % (w/v) NaCl with an oxidative metabolism using oxygen as the electron acceptor. Nitrate could not be used as the electron acceptor. Strain PLRT had a Chargaff’s coefficient (DNA G+C content) of 35.3 mol%. Phylogenetic analysis based on the sequence of the 16S rRNA gene placed the novel strain in the family Flavobacteriaceae (phylum ‘Bacteroidetes’), within a clade comprising Stenothermobacter spongiae, Nonlabens tegetincola, Sandarakinotalea sediminis, Persicivirga xylanidelens and Persicivirga dokdonensis. The closest neighbours of strain PLRT were P. xylanidelens and P. dokdonensis, sharing 95.2 and 95.5 % 16S rRNA gene sequence similarity, respectively. Phylogenetic inference and differential phenotypic characteristics demonstrated that strain PLRT represents a novel species of the genus Persicivirga, for which the name Persicivirga ulvanivorans sp. nov. is proposed. The type strain is PLRT ( = CIP 110082T = DSM 22727T).

Two marine bacterial strains, designated S2-4-21T and MT2-5-19, were isolated from two tidal flat sediments of cordgrass Spartina alterniflora and adjacent oyster culture field in Quanzhou bay, China, respectively. Both strains were Gram-staining-negative, rod-shaped, non-flagellated, non-motile, aerobic, had NaCl requirements, and contained carotenoid and flexirubin pigments. The 16S rRNA gene sequence similarity (99.8%), average nucleotide identity value (99.4%) and average amino acid identity (99.3%) between strain S2-4-21T and strain MT2-5-19 strongly supported that they belonged to a single species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2-4-21T and strain MT2-5-19 formed a monophyletic branch affiliated to the family Flavobacteriaceae , sharing similarities of 94.6% with Euzebyella marina CY01T and E. saccharophila 7SM30T, and of 94.1 and 92.8% with E. algicola MEBiC 12267T and Pseudozobellia thermophile DSM 19858T, respectively. Phylogenomic analysis based on the whole genome sequences supported that the two strains formed a distinct monophyletic clade within Flavobacteriaceae members, which was phylogenetically different from the clades of Euzebyella and Pseudozobellia . The major respiratory quinone was menaquinone MK-6. The major fatty acids (>10%) consisted of C15 : 0 iso, C16 : 0, summed feature 9 (C17 : 1 iso ω9c/C16 : 0 10-methyl) and C17 : 0 iso 3-OH. The polar lipid profiles of strain S2-4-21T and strain MT2-5-19 are identical, including phosphatidylethanolamine, four unidentified aminolipids, and four unidentified lipids. The genomic size was 4.9–5.0 Mb with genomic DNA G+C content of 41.5 mol%. Based on the above characteristics, strains S2-4-21T and MT2-5-19 represented a novel species of a novel genus in the family Flavobacteriaceae . Thus, Pareuzebyella sediminis gen. nov. sp. nov. is proposed with type strain S2-4-21T (=MCCC 1K03818T=KCTC 72152T), and another strain MT2-5-19 (=KCTC 72539=MCCC 1K03874).

A Gram-stain-positive actinobacterial strain, designated YJ01T, was isolated from a spinach farming field soil at Shinan in Korea. Strain YJ01T was aerobic, non-motile, non-spore-forming cocci with diameters of 1.5–1.9 µm, and was able to grow at 10–37 °C (optimum, 28–30 °C), at pH 4.5–9.0 (optimum, pH 7.0–8.0) and at salinities of 0–7.5 % (w/v) NaCl (optimum, 1.0 % NaCl). Sequence similarities of the 16S rRNA gene of strain YJ01T with closely related relatives were in the range 96.2–92.8 %, and the results of phylogenomic analysis indicated that strain YJ01T was clearly separated from species of genera in the family Intrasporangiaceae showing average nucleotide identity values of 84.2–83.4 %. The predominant isoprenoid quinone was identified as MK-8(H4) and the major fatty acids were iso-C15 : 0, iso-C16:1 h, iso-C16 : 0 and anteiso-C17 : 1ω9c. The diagnostic diamino acid of the peptidoglycan was ornithine, and the interpeptide bridge was l-Orn–Gly2–d-Glu. The major polar lipids were identified as diphosphatidylglycerol, phosphatidylglycerol, phosphatidylserine, an unidentified phosphatidylglycolipid, two unidentified phosphoaminolipids and an unidentified phosphoglycoaminolipid. The G+C content of the genome was 70.1 mol%. On the basis of phenotypic and chemotaxonomic properties and phylogenetic and phylogenomic analyses using 16S rRNA gene sequences and whole-genome sequences, strain YJ01T is considered to represent a novel species of a new genus in the family Intrasporangiaceae , for which the name Segeticoccus rhizosphaerae gen. nov. sp. nov. is proposed. The type strain of Segeticoccus rhizosphaerae is YJ01T (=KACC 19547T=NBRC 113173T).
