A Gram-negative, motile, non-spore-forming bacterial strain, designated MJ07T, was isolated from a farm soil and was characterized to determine its taxonomic position by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ07T belongs to the family Alcaligenaceae, class Betaproteobacteria, and is related most closely to Pusillimonas ginsengisoli KCTC 22046T (98.6 % sequence similarity) and Pusillimonas noertemannii BN9T (96.9 %). The levels of 16S rRNA gene sequence similarity between strain MJ07T and members of all other recognized species of the family Alcaligenaceae were below 95.2 %. The G+C content of the genomic DNA of strain MJ07T was 59.4 mol%. The detection of a quinone system with ubiquinone Q-8 as the major respiratory lipoquinone, putrescine as the predominant polyamine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and two unknown aminolipids as major polar lipids and a fatty acid profile with C16 : 0 (32.0 %), C17 : 0 cyclo (24.7 %) and C19 : 0 cyclo ω8c (11.5 %) as the major components supported the affiliation of strain MJ07T to the genus Pusillimonas. Strain MJ07T exhibited relatively low levels of DNA–DNA relatedness with respect to P. ginsengisoli KCTC 22046T (50±8 %) and P. noertemannii KACC 13183T (18±7 %). On the basis of its phenotypic and genotypic properties together with its phylogenetic distinctiveness, strain MJ07T (=KCTC 22455T =JCM 16386T) should be classified in the genus Pusillimonas as the type strain of a novel species, for which the name Pusillimonas soli sp. nov. is proposed.

A Gram-negative, non-spore-forming, motile, facultatively anaerobic bacterium, designated strain MJ06T, was isolated from oil-contaminated soil and was characterized taxonomically by using a polyphasic approach. Strain MJ06T contained ubiquinone Q-8 as the major respiratory lipoquinone, putrescine as the predominant polyamine and phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol as major polar lipids. The G+C content of the genomic DNA of strain MJ06T was 66.2 mol%. The major fatty acids were summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH; 32.5 %), C16 : 0 (22.8 %) and summed feature 7 (one or more of C18 : 1 ω7c, C18 : 1 ω9t and C18 : 1 ω12t; 14.9 %). Comparative 16S rRNA gene sequence analysis showed that strain MJ06T belonged to the family Alcaligenaceae, class Betaproteobacteria, and joined the evolutionary radiation enclosed by the genus Castellaniella. Levels of 16S rRNA gene sequence similarity between strain MJ06T and its phylogenetically closest relatives, Castellaniella denitrificans NKNTAUT, Castellaniella defragrans 54PinT, Castellaniella ginsengisoli DCY36T and Castellaniella caeni Ho-11T, were 98.6, 98.3, 97.8 and 97.3 %, respectively. Levels of similarity between strain MJ06T and the type strains of all other recognized species in the family Alcaligenaceae were below 95.0 %. Strain MJ06T exhibited relatively low levels of DNA–DNA relatedness with respect to C. defragrans DSM 12141T (52 %), C. denitrificans DSM 11046T (31 %), C. ginsengisoli KCTC 22398T (18 %) and C. caeni KCTC 12197T (15 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ06T is considered to represent a novel species of the genus Castellaniella, for which the name Castellaniella daejeonensis sp. nov. is proposed. The type strain is MJ06T (=KCTC 22454T =JCM 16240T).

A bacterial strain, DC-186T, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 °C and pH 5.5–8.0. Strain DC-186T was positive in tests for catalase, oxidase and β-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C16 : 1/iso-C15 : 0 2-OH (42 %) and iso-C15 : 0 (26 %), the major respiratory quinone was menaquinone-7 and the genomic DNA G+C content was 42 mol%. 16S rRNA gene sequence analysis and phenetic characterization indicated that this organism belongs to the phylum Bacteroidetes and revealed its affiliation to the family Sphingobacteriaceae. Of recognized taxa, strain DC-186T was most closely related to Sphingobacterium daejeonense (90 % sequence similarity) based on 16S rRNA gene sequence analysis. The low 16S rRNA gene sequence similarity with other recognized taxa and the identification of distinctive phenetic features for this isolate support the definition of a new genus within the family Sphingobacteriaceae. The name Pseudosphingobacterium domesticum gen. nov., sp. nov. is proposed, with strain DC-186T (=CCUG 54353T=LMG 23837T) as the type strain.

Two bacterial strains isolated from chicken caecum, C46T and C47, were characterized using a polyphasic taxonomic approach that included analysis of the phenotypic and biochemical features, cellular fatty acid profiles, menaquinone profiles and phylogenetic position (using 16S rRNA gene sequence analysis). The 16S rRNA gene sequence analysis showed that these strains belonged to the family Porphyromonadaceae. These strains shared 100 % 16S rRNA gene sequence similarity with each other and were related to Parabacteroides distasonis (showing 86 % sequence similarity). The strains were found to be obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative rods. Growth of the strains was inhibited on medium containing 20 % bile. The major menaquinones of the isolates were MK-11 and MK-12. This menaquinone composition was different from those of other genera of the family Porphyromonadaceae, such as Parabacteroides (in which the predominant menaquinones are MK-9 and MK-10), Porphyromonas (MK-9 and MK-10) and Tannerella (MK-10 and MK-11). This is an important chemotaxonomic characteristic of these micro-organisms. The DNA G+C content of strain C46T is 52.0 mol%. On the basis of these data, strains C46T and C47 represent a novel genus and species, for which the name Barnesiella viscericola gen. nov., sp. nov. is proposed. The type strain of Barnesiella viscericola is C46T (=JCM 13660T=DSM 18177T).

A Gram-positive, non-motile, non-spore-forming, aerobic, coccoid-shaped bacterium, designated BXN5-13T, was isolated from the soil of a ginseng field from Baekdu Mountain in Jilin district, China. Strain BXN5-13T grew optimally at 30 °C and pH 6.5–7.5 with 0–2 % (w/v) NaCl. Strain BXN5-13T had β-glucosidase activity that was connected with ginsenoside-converting ability, so that it was able to convert ginsenoside Rb1 to ginsenoside F2. On the basis of 16S rRNA gene sequence analysis, the closest phylogenetic relatives of strain BXN5-13T were Phycicoccus aerophilus 5516T-20T (98.4 % 16S rRNA gene sequence similarity), P. bigeumensis MSL-03T (98.3 %), P. dokdonensis DS-8T (97.9 %) and P. jejuensis KSW2-15T (96.9 %). Lower sequence similarity (<97.0 %) was found with the type strains of other recognized species of the family Intrasporangiaceae. The predominant quinone was MK-8(H4). The major fatty acids (>10 %) were iso-C15 : 0, C17 : 0, anteiso-C15 : 0 and iso-C16 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositol. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The chemotaxonomic data and the high genomic DNA G+C content of strain BXN5-13T (70.8 mol%) supported its affiliation with the genus Phycicoccus. DNA–DNA relatedness between strain BXN5-13T and its closest phylogenetic neighbours was below 16 %. Strain BXN5-13T represents a novel species within the genus Phycicoccus, for which the name Phycicoccus ginsenosidimutans sp. nov. is proposed. The type strain is BXN5-13T (=KCTC 19419T=DSM 21006T=LMG 24462T).

A novel bacterial strain designated B3AT, isolated from shrimp paste, was investigated by a polyphasic taxonomic approach. Cells stained Gram-positive and were aerobic, non-pigmented, sporulating and rod-shaped with a polar flagellum. 16S rRNA gene sequence analysis indicated that strain B3AT belonged to the class Bacilli and was a member of the family Bacillaceae. Strain B3AT shared low levels of 16S rRNA gene sequence similarity (<94.0 %) with members of other genera in the family Bacillaceae and was most closely related to Halalkalibacillus halophilus BH2T (93.8 % sequence similarity). The isolate was able to grow at 20–45 °C, with 0.5–15 % NaCl and at pH 6–9. Menaquinone with seven isoprene units (MK-7) was the major respiratory quinone and 16 : 0 iso, 15 : 0 anteiso and 14 : 0 iso were the major fatty acids. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The characteristic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The DNA G+C content was 45.3 mol%. On the basis of 16S rRNA gene sequence analysis in combination with chemotaxonomic and physiological data, strain B3AT represents a novel genus and species in the family Bacillaceae for which the name Allobacillus halotolerans gen. nov., sp. nov. is proposed. The type strain of Allobacillus halotolerans is B3AT ( = BCRC 17939T  = LMG 24826T).

Twenty morphologically different strains were chosen from French wheat sourdough isolates. Cells were Gram-positive, non-spore-forming, non-motile rods. The isolates were identified using amplified-fragment length polymorphism, randomly amplified polymorphic DNA and 16S rRNA gene sequence analysis. All isolates were members of the genus Lactobacillus. They were identified as representing Lactobacillus plantarum, Lactobacillus paralimentarius, Lactobacillus sanfranciscensis, Lactobacillus spicheri and Lactobacillus sakei. However, two isolates (LP38T and LP39) could be clearly discriminated from recognized Lactobacillus species on the basis of genotyping methods. 16S rRNA gene sequence similarity and DNA–DNA relatedness data indicate that the two strains belong to a novel Lactobacillus species, for which the name Lactobacillus hammesii is proposed. The type strain is LP38T (=DSM 16381T=CIP 108387T=TMW 1.1236T).

A non-motile and non-endospore-forming rod, strain NBRC 16403T, was isolated from the phyllosphere of a sedge (Carex sp.). 16S rRNA gene sequence analysis indicated that strain NBRC 16403T was closely related to Herbiconiux solani DSM 19813T (98.6 % 16S rRNA gene sequence similarity), Herbiconiux ginsengi wged11T (97.8 %) and Herbiconiux moechotypicola RB-62T (97.8 %). The peptidoglycan (B2γ type) contained d- and l-2,4-diaminobutyric acids, d-alanine, glycine and threo-3-hydroxyglutamic acid, which replaced glutamic acid almost completely. The predominant menaquinones were MK-10 and MK-11. The polar lipid pattern comprised diphosphatidylglycerol, phosphatidylglycerol, three glycolipids and minor amounts of other polar lipids. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0; no cyclohexyl-C17 : 0 was detected. The DNA G+C content was 71.0 mol%. The results of phylogenetic and DNA–DNA relatedness studies, along with phenotypic differences between strain NBRC 16403T and recognized members of the genus Herbiconiux, indicated that the isolate should be assigned to a novel species of the genus Herbiconiux, for which the name Herbiconiux flava sp. nov. is proposed. The type strain is NBRC 16403T ( = VKM Ac-2058T).

Four Gram-negative, orange-coloured, aerobic, heterotrophic bacteria were isolated from sediment samples collected on the Pacific coast of Japan near the cities of Toyohashi and Katsuura. 16S rRNA gene sequence analysis indicated that these strains form a distinct lineage within the family Flavobacteriaceae. The four isolates shared 99.9–100 % 16S rRNA gene sequence similarity with each other and showed 88–90.9 % similarity with their neighbours in the family Flavobacteriaceae. The four strains also shared high DNA–DNA reassociation values of 67–99 % with each other. All the strains grew at 37 °C but not at 4 °C, and degraded gelatin, starch and DNA. The major fatty acids were i-C15 : 0, a-C15 : 0, i-C16 : 0 and i-C17 : 0 3-OH. However, two common fatty acids of members of the Flavobacteriaceae, i-C15 : 1 and a-C15 : 1, were absent in these strains. The DNA G+C contents of the four strains were in the range 35–37 mol%. On the basis of the polyphasic evidence, it was concluded that these strains should be classified as a novel genus and a novel species in the family Flavobacteriaceae, for which the name Sandarakinotalea sediminis gen. nov., sp. nov. is proposed. The type strain of Sandarakinotalea sediminis is CKA-5T (=NBRC 100970T=LMG 23247T).

The taxonomic position of four Gram-negative, rod-shaped, golden-yellow-coloured bacteria isolated from marine sediments was determined. Analysis of the almost complete 16S rRNA gene sequences indicated that these isolates belong to the family Flavobacteriaceae. An unclassified bacterium, NBRC 15975, was found to be the closest relative, showing 16S rRNA gene sequence similarity of 93 %; other related genera shared only 87·9–90·5 % similarity. In contrast, the four isolates shared high levels of 16S rRNA gene sequence similarity (99·3–99·7 %) and high DNA–DNA reassociation values (93–104 %). The isolates could be differentiated phenotypically from other genera by the abilities to reduce nitrate and to degrade gelatin, casein and starch. The only respiratory quinone was MK-6, and the major fatty acids were iso-C15 : 0, iso-C15 : 1, anteiso-C15 : 0, iso-C17 : 1 ω9c and iso-C17 : 0 3-OH. The DNA G+C content was 38–40 mol%. Differentiating phenotypic characteristics and large phylogenetic distances between the isolates and previously published genera indicated that the isolates constitute a novel genus, for which the name Sediminicola gen. nov. is proposed. The type species is Sediminicola luteus sp. nov. (type strain CNI-3T=NBRC 100966T=LMG 23246T).

Two bacterial strains (SC-089T and SC-092T) isolated from sewage sludge compost were characterized by using a polyphasic approach. The isolates were Gram-negative short rods, catalase- and oxidase-positive, and showed good growth at 30 °C, at pH 7 and with 1 % (w/v) NaCl. Ubiquinone 8 was the major respiratory quinone, and phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol were amongst the major polar lipids. On the basis of 16S rRNA gene sequence analysis, the strains were observed to be members of the family Alcaligenaceae, but could not be identified as members of any validly described genus. The low levels of 16S rRNA gene sequence similarity to other recognized taxa, together with comparative analysis of phenotypic traits and chemotaxonomic markers, supported the proposal of a new genus within the family Alcaligenaceae, for which the name Candidimonas gen. nov. is proposed. Strains SC-089T and SC-092T, which shared 99.1 % 16S rRNA gene sequence similarity, could be differentiated at the phenotypic level, and DNA–DNA hybridization results supported their identification as representing distinct species. The names proposed for these novel species are Candidimonas nitroreducens sp. nov. (type strain, SC-089T = LMG 24812T = CCUG 55806T) and Candidimonas humi sp. nov. (type strain, SC-092T = LMG 24813T = CCUG 55807T).
