Abstract Two aerobic, Gram-stain variable, catalase and oxidase-positive, spore-forming, motile rods of strain UniB2T and UniB3T, were isolated from digestive syrup containing fungal diastase (10 mg/ml), pepsin (2 mg/ml) and sugar base containing polyethene glycol. Based on 16S rRNA gene sequence analysis, strain UniB2T has the highest sequence similarity with Paenibacillus humicus NBRC 102415T (98.30 %) and strain UniB3T showed the highest sequence similarity with Niallia circulans DSM 11T (98.95 %). The DNA G+C content of UniB2T was 63.74 mol %. The dDDH and ANI values between the strain UniB2T and its phylogenetically close relative were <38.3 % and <89.55 %, respectively. The major fatty acids of the strain UniB2T were C16:00 (13.9 %), C15:0 anteiso (39.7 %), C17:0 anteiso (15.5 %). The DNA G+C content of UniB3T was 35.6 mol%. The dDDH and ANI values between the strain UniB3T and its close relatives were <29.1 % and 84.62%, respectively. The major fatty acids of strain UniB3T were C16:0 (13.54 %), C15:0 anteiso (40.09 %) and C17:0 anteiso (16.03 %). Major polar lipids for both strains were Diphosphotidylglycerol and Phosphatidylethanolamine. Additionally, both the strains showed unique carbon utilization and assimilation pattern that differentiated them from their phylogenetically related neighbours. These phenotypic, genotypic and chemotaxonomic characters indicated the strains UniB2T and UniB3T represent two novel species for which the names Paenibacillus albicerus sp. nov. (Type strain UniB2T =MCC 3997T =KCTC 43095T =JCM34513T) and Niallia alba sp. nov. (Type strain UniB3T = MCC 3998T =KCTC 43235T =JCM 34492T) are proposed.

Two bacterial strains, designated GH34-4T and GH41-7T, were isolated from greenhouse soil cultivated with cucumber. The bacteria were strictly aerobic, Gram-negative, rod-shaped and oxidase- and catalase-positive. 16S rRNA gene sequence analysis indicated that these strains belong to the genus Lysobacter within the Gammaproteobacteria. Strain GH34-4T showed highest sequence similarity to Lysobacter yangpyeongensis GH19-3T (97.5 %) and Lysobacter koreensis Dae16T (96.4 %), and strain GH41-7T showed highest sequence similarity to Lysobacter antibioticus DSM 2044T (97.5 %), Lysobacter enzymogenes DSM 2043T (97.5 %) and Lysobacter gummosus ATCC 29489T (97.4 %). Levels of DNA–DNA relatedness indicated that strains GH34-4T and GH41-7T represented species clearly different from L. yangpyeongensis, L. antibioticus, L. enzymogenes and L. gummosus. The major cellular fatty acids of strains GH34-4T and GH41-7T were iso-C16 : 0, iso-C15 : 0 and iso-C17 : 1 ω9c, and the major isoprenoid quinone was Q-8. The DNA G+C contents of GH34-4T and GH41-7T were 62.5 and 66.6 mol%, respectively. On the basis of the polyphasic taxonomic data presented, it is evident that each of these strains represents a novel species of the genus Lysobacter, for which the names Lysobacter niabensis sp. nov. (type strain GH34-4T=KACC 11587T=DSM 18244T) and Lysobacter niastensis sp. nov. (type strain GH41-7T=KACC 11588T=DSM 18481T) are proposed.

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

A Gram-negative, rod-shaped, motile, non-spore-forming bacterium, designated strain A62-14BT, was isolated from a constant-temperature, spring-fed, freshwater lake. On the basis of the complete 16S rRNA gene sequence, strain A62-14BT was shown to belong to the class Gammaproteobacteria, being most closely related to Rheinheimera sp. HTB082 (96.2 % sequence similarity), Rheinheimera baltica (95.01 %), Rheinheimera pacifica (96.35 %), Rheinheimera perlucida and Alishewanella fetalis (95.9 %). The major fatty acids (C16 : 1 ω7c, 38.56 %; C16 : 0, 19.04 %; C12 : 0 3-OH, 12.83 %; C18 : 1 ω7c, 7.70 %) and the motility of strain A62-14BT support its affiliation to the genus Rheinheimera. The salt intolerance of strain A62-14BT, together with the results of other physiological and biochemical tests, allowed the differentiation of this strain from the three species of the genus Rheinheimera with validly published names. Therefore strain A62-14BT represents a novel species of the genus Rheinheimera, for which the name Rheinheimera texasensis sp. nov. is proposed. The type strain is A62-14BT (=ATCC BAA-1235T=DSM 17496T). The description of the genus Rheinheimera is emended to reflect the halointolerance and freshwater origin of strain A62-14BT.

A Gram-positive, non-motile, endospore-forming bacterium, designated Gsoil 1517T, was isolated from soil of a ginseng field in Pocheon Province (South Korea) and was characterized in order to determine its taxonomic position, using a polyphasic approach. It was found to rod-shaped and aerobic or facultatively anaerobic. It grew optimally at 30 °C and at pH 6.5–7.0. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 1517T forms a distinct phylogenetic lineage within the genus Bacillus, being related to Bacillus funiculus JCM 11201T (96.8 %). The strain showed less than 94.3 % sequence similarity with other Bacillus species. The G+C content of the genomic DNA was found to be 47.8 mol% and the predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0 (42.4 %), anteiso-C15 : 0 (17.4 %), iso-C14 : 0 (9.7 %) and C16 : 0 (6.0 %). On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1517T represents a novel species of the genus Bacillus, for which the name Bacillus panaciterrae sp. nov. is proposed. The type strain is Gsoil 1517T (=KCTC 13929T=CCUG 52470T=LMG 23408T).

Ten strains of Gram-stain-negative, non-spore-forming, non-motile coccobacilli were isolated from the plaster wall surface of 1300-year-old mural paintings inside the stone chamber of the Takamatsuzuka tumulus in Asuka village (Asuka-mura), Nara Prefecture, Japan. Based on 16S rRNA gene sequence analysis of the isolates, they belonged to the proteobacterial genus Bordetella (class Betaproteobacteria) and could be separated into three groups representing novel lineages within the genus Bordetella. Three isolates were selected, one from each group, and identified carefully using a polyphasic approach. The isolates were characterized by the presence of Q-8 as their major ubiquinone system and C16 : 0 (30.0–41.8 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 10.1–27.0 %) and C17 : 0 cyclo (10.8–23.8 %) as the predominant fatty acids. The major hydroxy fatty acids were C12 : 0 2-OH and C14 : 0 2-OH. The DNA G+C content was 59.6–60.0 mol%. DNA–DNA hybridization tests confirmed that the isolates represented three separate novel species, for which the names Bordetella muralis sp. nov. (type strain T6220-3-2bT = JCM 30931T = NCIMB 15006T), Bordetella tumulicola sp. nov. (type strain T6517-1-4bT = JCM 30935T = NCIMB 15007T) and Bordetella tumbae sp. nov. (type strain T6713-1-3bT = JCM 30934T = NCIMB 15008T) are proposed. These results support previous evidence that members of the genus Bordetella exist in the environment and may be ubiquitous in soil and/or water.

One bacterial strain, designated 5GH38-5T, which was characterized as aerobic, Gram-staining-negative, non-flagellated rods, was isolated from a soil sample from a greenhouse in Sangju region, Republic of Korea. It grew at temperatures of 15–45 °C, pH 5.0–9.0 and NaCl concentrations (w/v) of 0–3.0 %. 16S rRNA gene sequence analysis showed the strain was closely related to Pseudoxanthomonas kaohsiungensis J36T (97.3 %), Pseudoxanthomonas suwonensis 4M1T (96.8 %), Pseudoxanthomonas daejeonensis TR6-08T (96.7 %) and Pseudoxanthomonas kalamensis JA40T (96.7 %). Its major fatty acids were iso-C16 : 0, anteiso-C15 : 0 and iso-C15 : 0. The predominant ubiquinone was Q-8. The major polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content was 71.1 mol%. The DNA–DNA hybridization value between strain 5GH38-5T and P. kaohsiungensis J36T was less than 70 %. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain 5GH38-5T could be clearly distinguished from closely related members of the genus Pseudoxanthomonas. Therefore, the results of this study indicated the existence of a novel species of the genus Pseudoxanthomonas, for which we propose the name Pseudoxanthomonas sangjuensis sp. nov., with strain 5GH38-5T ( = KACC 16961T = DSM 28345T = JCM 19948T) as the type strain.

The major respiratory quinones were MK-9, MK-10 and MK-11. The major fatty acids were anteiso-C15 : 0 (41.6  %) and anteiso-C17 : 0 (32.8 %). The predominant cellular polar lipids were diphosphatidylglycerol and phosphatidylglycerol. Cell wall sugars comprised galactose, glucose, ribose and rhamnose. 16S rRNA gene sequence analysis of strain G4T showed high similarity with Agrococcus baldri (98.9 %), Agrococcus citreus (97.8 %), Agrococcus jenensis (97.3 %) and Agrococcus terreus (97.0 %). Sequence similarity with the type strains of the other species of the genus Agrococcus was less than 97.0 %. The DNA–DNA relatedness of strain G4T with the type strains of Agrococcus baldri, Agrococcus citreus, Agrococcus jenensis and Agrococcus terreus was less than 70 %. On the basis of the physiological, biochemical and chemotaxonomic characteristics, strain G4T should be classified as the type strain of a novel species of the genus Agrococcus, for which the name Agrococcus carbonis sp. nov. is proposed. The type strain is G4T ( = MTCC 10213T  = DSM 22965T).

Two xylan-degrading bacterial strains were isolated from a decayed Ulmus nigra tree in Spain. The isolates were Gram-positive, non-motile, aerobic and formed substrate mycelium which fragmented into irregular rods. 16S rRNA gene sequence analysis indicated that the isolates form a separate branch within the genus Agromyces phylogenetic cluster, with Agromyces mediolanus DSM 20152T being their closest relative (97·7 and 97·6 % sequence similarity). Catalase, nitrate reduction and urease tests differentiated these strains from A. mediolanus. Cell-wall peptidoglycan composition, major menaquinone, predominant fatty acids and phospholipid pattern were typical of the genus Agromyces. The DNA G+C content determined for the type strain XIL01T was 72 mol%. Based on the data presented, a novel species Agromyces ulmi sp. nov. is proposed. The type strain is XIL01T (=LMG 21954T=DSM 15747T).

A Gram-negative, rod-shaped bacterium (CC-JY-1T) was isolated on nutrient agar from a soil sample collected from an oil-contaminated site located in Chyai county, Taiwan. 16S rRNA gene sequence analysis demonstrated that this isolate is unique, showing 96.7 % sequence similarity to the type strain of Arenimonas donghaensis and similarities of 93.0–93.8 % to species of the genera Thermomonas, Lysobacter and Silanimonas. The presence of ubiquinone Q-8, a polar lipid profile consisting of the major compounds diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine and the fatty acid profile were in accordance with the phylogenetic affiliation of CC-JY-1T. DNA–DNA reassociation experiments between CC-JY-1T and A. donghaensis KACC 11381T resulted in a mean relatedness value of 32 %, indicating that strain CC-JY1T represents a novel species in the genus Arenimonas, for which we propose the name Arenimonas malthae sp. nov. The type strain is CC-JY-1T (=CCUG 53596T =CIP 109310T).
