A Gram-stain-positive thermophilic bacterium, designated strain Nis3T, was isolated from compost. The strain grew at 23–57 °C (optimum, 50 °C); no growth was observed below 15 or above 60 °C. The pH range for growth was 5.9–8.8 (optimum, 7.0); no growth was observed below pH 5.4 or above pH 9.3. The DNA G+C content of strain Nis3T was 63.4 mol%. The dominant quinone type was ubiquinone Q-10. The major fatty acids were C18 : 1ω7c, C19 : 0ω8c cyclo and C18 : 0. The polar lipids comprised phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylmonomethylethanolamine, an unknown glycolipid and a ninhydrin-positive phospholipid. 16S rRNA gene sequence analysis assigned this bacterium to the family Phyllobacteriaceae in the Alphaproteobacteria but it shared less than 95.2 % sequence similarity with other members of the family. The chemotaxonomic and phenotypic characteristics of strain Nis3T differed in some respects from those of members of the family Phyllobacteriaceae . Therefore, strain Nis3T is considered to represent a novel species of a new genus in the family Phyllobacteriaceae , for which the name Thermovum composti gen. nov., sp. nov. is proposed. The type strain is Nis3T ( = JCM 17863T = KCTC 23707T).

A Gram-stain-negative, aerobic coccus, designated CK1056T, was isolated from coastal sediment of Xiaoshi Island, Weihai, PR China. Strain CK1056T was found to grow at 15–37 °C (optimum, 30 °C), with 0.5–6.5 % (w/v) NaCl (optimum, 3.5 %) and displayed alkaliphilic growth within the pH range of pH 6.5–10.0 (optimum, pH 8.0). The major fatty acids identified were iso-C15 : 0 and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c). The main polar lipids consisted of aminophosphoglycolipid and phosphatidylethanolamine. The predominant respiratory quinone was MK-7. The G+C content of the genomic DNA was 54.0 mol%. The result of the 16S rRNA gene sequence analysis confirmed the affiliation of this micro-organism to the family Puniceicoccaceae , with Coraliomargarita akajimensis KCTC 12865T as its closest relative with only 88.0 % sequence similarity. From the taxonomic data obtained in this study, we propose that the new marine isolate be placed into a novel species within a novel genus in the family Puniceicoccaceae , phylum Verrucomicrobia , for which the name Oceanipulchritudo coccoides gen. nov., sp. nov. is proposed. The type strain is CK1056T (=KCTC 72798T=MCCC 1H00425T).

A novel anaerobic succinate-producing bacterium, strain ZWBT, was isolated from sludge collected from a biogas desulfurization bioreactor (Eerbeek, the Netherlands). Cells were non-spore-forming, motile, slightly curved rods (0.4–0.5 µm in diameter and 2–3 µm in length), and stained Gram-negative. The temperature range for growth was 25–40 °C, with an optimum at 37 °C. The pH range for growth was 7.0–9.0, with an optimum at pH 7.5. Strain ZWBT was able to ferment glycerol and several carbohydrates mainly to H2, succinate and acetate. Sulfur and fumarate could be used as electron acceptors by strain ZWBT. The G+C content of the genomic DNA was 37.6 mol%. The most abundant fatty acids were iso-C14 : 0 and iso-C16 : 0 DMA. On the basis of 16S rRNA gene sequence similarity, strain ZWBT belongs to the family Ruminococcaceae and it is distantly related to Saccharofermentans acetigenes JCM 14006T (92.1 %). Based on the physiological features and phylogenetic analysis, strain ZWBT represents a novel species of a new genus, for which the name Ercella succinigenes gen. nov., sp. nov. is proposed. The type strain of Ercella succinigenes is ZWBT ( = DSM 27333T = JCM 19283T).

Two Gram-positive, moderately thermophilic, endospore-forming, rod-shaped, motile bacteria, designated PDF25T and PDF30, were isolated from Karakoc hot spring in the province of Izmir, Turkey, and were characterized in order to determine their phylogenetic positions. 16S rRNA gene sequence analysis revealed that the two strains belonged to the genus Brevibacillus ; strain PDF25T showed highest sequence similarity to strain PDF30 (99.4 %) and Brevibacillus thermoruber DSM 7064T (98.5 %). The major fatty acids of strain PDF25T were iso-C15 : 0 (39.30 %), anteiso-C15 : 0 (26.10 %) and iso-C16 : 0 (14.75 %). Polar lipid analysis revealed diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, and a variety of unidentified aminophospholipids, phospholipids and aminolipids. The major isoprenoid quinone was MK-7. The G+C content of the genomic DNA was 56.09 mol%. DNA–DNA hybridization experiments revealed 58 % relatedness between strain PDF25T and B. thermoruber DSM 7064T. Based on these data, the two strains are considered to represent a novel species of the genus Brevibacillus , for which the name Brevibacillus aydinogluensis sp. nov. is proposed. The type strain is PDF25T ( = DSM 24395T = LMG 26289T).

An obligately anaerobic bacterial strain designated KC3T was isolated from a rice straw-degrading culture, for which soil of a Japanese rice field was used as the inoculum. Cells of strain KC3T were determined to be non-cellulolytic, Gram-stain-positive, non-motile, ellipsoidal, spore-forming rods, 0.8–1×4–25 µm. Endospores were formed at a terminal position in elongated cells (12–25 µm, mean 15 µm). The temperature range for growth was 20–50 °C, with an optimum at 37 °C. The pH range for growth was 5.0–7.5, with an optimum at pH 6.0 (slightly acidophilic). Strain KC3T fermented cellobiose to lactate, butyrate, acetate, formate, hydrogen and carbon dioxide. The major cellular fatty acids (>10 %) were C14 : 0, C16 : 0 and C19 : 0 cyclo 11,12 dimethylacetal. The DNA G+C content of strain KC3T was 37.5 mol%. 16S rRNA gene sequence analysis revealed that strain KC3T shared low sequence similarity (<93 %) with type strains of the genus Clostridium sensu stricto (Clostridium rRNA cluster I). Analyses of the DNA gyrase A and ATP synthase beta subunit sequences supported the affiliation of strain KC3T to the genus Clostridium sensu stricto. The evidence presented here indicates that strain KC3T represents a novel species of the genus Clostridium , for which the name Clostridium oryzae sp. nov. is proposed. The type strain of Clostridium oryzae is KC3T ( = DSM 28571T = NBRC 110163T).

An aerobic, Gram-stain-negative, agarolytic rod-shaped bacterium, designated KMM 9504T, was isolated from a sediment sample collected from the seashore of the Sea of Japan. Comparative 16S rRNA gene sequence analysis showed that strain KMM 9504T belonged to the genus Simiduia as it was most closely related to Simiduia areninigrae KCTC 23293T (97.3 % sequence similarity). Strain KMM 9504T was characterized by the major ubiquinone Q-8, and by the predominance of C16 : 1ω7c, C17 : 1ω8c, followed by C16 : 0, C15 : 0, C17 : 0 and C12 : 1 in its fatty acid profile. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminophospholipid, an unknown aminolipid, unknown phospholipids, and unknown lipids. Based on the distinctive phenotypic characteristics, phylogenetic analysis and DNA–DNA hybridization results, it is concluded that strain KMM 9504T represents a novel species of the genus Simiduia , for which the name Simiduia litorea sp. nov. is proposed. The type strain of the species is strain KMM 9504T ( = NRIC 0917T = JCM 19759T).
