A newly isolated, facultatively methylotrophic bacterium (strain MUSAT) was investigated. The isolate was strictly aerobic, Gram-stain-negative, asporogenous, motile, rod-shaped and multiplied by binary fission. The strain utilized methanol, methylamine and an apparently narrow range of multi-carbon compounds, but not methane, dichloromethane or CO2/H2, as the carbon and energy sources. Growth occurred at pH 5.5–9.5 (optimum, pH 7.0) and 16–40 °C (optimum, 28–30 °C). The major fatty acids of methanol-grown cells were C18 : 1ω7c, C18 : 0 and 11-methyl-C18 : 1ω7c . The predominant phospholipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol and phosphatidylmonomethylethanolamine. The major ubiquinone was Q-10. The strain had methanol and methylamine dehydrogenases as well as the enzymes of the N-methylglutamate pathway (lyases of γ-glutamylmethylamide and N-methylglutamate). C1 assimilation occurs via the isocitrate lyase-negative serine pathway. Ammonium was assimilated by glutamate dehydrogenase and the glutamate cycle (glutamate synthase/glutamine synthetase). The DNA G+C content of the strain was 64.5 mol% (determined from the melting temperature). Based on 16S rRNA gene sequence similarity (97.0–98.9 %) and DNA–DNA relatedness (36–38 %) with representatives of the genus Methylopila ( Methylopila capsulata IM1T and Methylopila jiangsuensis JZL-4T) the isolate was classified as a novel species of the genus Methylopila , for which the name Methylopila musalis sp. nov. is proposed. The type strain is MUSAT ( = VKM B-2646T = DSM 24986T = CCUG 61696T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

A strictly aerobic, thermophilic, moderately acidophilic, non-spore-forming bacterium, strain P373T, was isolated from geothermally heated soil at Waikite, New Zealand. Cells were filamentous rods, 0.2–0.4 µm in diameter and grew in chains up to 80 µm in length. On the basis of 16S rRNA gene sequence similarity, strain P373T was shown to belong to the family Chitinophagaceae (class Sphingobacteriia ) of the phylum Bacteroidetes , with the most closely related cultivated strain, Chitinophaga pinensis UQM 2034T, having 87.6 % sequence similarity. Cells stained Gram-negative, and were catalase- and oxidase-positive. The major fatty acids were i-15 : 0 (10.8 %), i-17 : 0 (24.5 %) and i-17 : 0 3-OH (35.2 %). Primary lipids were phosphatidylethanolamine, two unidentified aminolipids and three other unidentified polar lipids. The presence of sulfonolipids (N-acyl-capnines) was observed in the total lipid extract by mass spectrometry. The G+C content of the genomic DNA was 47.3 mol% and the primary respiratory quinone was MK-7. Strain P373T grew at 35–63 °C with an optimum temperature of 60 °C, and at pH 5.5–8.7 with an optimum growth pH of 7.3–7.4. NaCl tolerance was up to 5 % (w/v) with an optimum of 0.1–0.25 % (w/v). Cell colonies were non-translucent and pigmented vivid yellow–orange. Cells displayed an oxidative chemoheterotrophic metabolism. The distinct phylogenetic position and the phenotypic characteristics separate strain P373T from all other members of the phylum Bacteroidetes and indicate that it represents a novel species in a new genus, for which the name Thermoflavifilum aggregans gen. nov., sp. nov. is proposed. The type strain of the type species is P373T ( = ICMP 20041T = DSM 27268T).
