Three Gram-negative, anaerobic, rod-shaped bacteria (strains CB40, CB41 and CB42T) were isolated from human faeces. Based on phylogenetic analysis and specific phenotypic characteristics, these strains were included in the genus Bacteroides, and 16S rRNA gene sequence analysis indicated that these strains represented a novel species. The strains were most closely related to the type strains of Bacteroides barnesiae and Bacteroides salanitronis, with sequence similarities of 93.4 and 89.8 %, respectively. The G+C content of strain CB42T is 44.7 mol%. Major fatty acids were anteiso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH and C18 : 1 ω9c. On the basis of the data presented, a novel Bacteroides species, Bacteroides coprophilus sp. nov., is proposed, with CB42T (=JCM 13818T=DSM 18228T) as the type strain.

A novel bacterium, designated strain H3-R18T, was isolated from seashore sand collected from Homi cape, Pohang city, Korea. Cells were Gram-negative, aerobic, non-motile, cream-coloured, mesophilic and slightly halotolerant. 16S rRNA gene sequence analysis indicated that the organism was a member of the genus Pseudomonas, but the sequence showed ⩽96.3 % sequence similarity to that of the type strains of all recognized Pseudomonas species. Highest sequence similarities were to Pseudomonas brenneri CFML 97-391T (96.3 %) and Pseudomonas migulae CIP 105470T (96.3 %). The major fatty acids were summed feature 3 and C16 : 0, with lesser amounts of C12 : 0, C12 : 0 3-OH, C18 : 1ω7c and C14 : 0. The major isoprenoid quinone was Q-9. The DNA G+C content was 64.0 mol%. The phylogenetic, phenotypic and genetic properties of strain H3-R18T suggest that it represents a novel species, for which the name Pseudomonas pohangensis sp. nov. is proposed. The type strain is H3-R18T (=KACC 11517T=DSM 17875T).

Two yellow-pigmented, Gram-negative, rod-shaped bacterial strains, GH1-10T and GH29-5T, were isolated from greenhouse soils in Korea. 16S rRNA gene sequence analysis indicated that these strains were related to members of the genus Flavobacterium. Strain GH1-10T was most closely related to Flavobacterium psychrolimnae and Flavobacterium denitrificans, with sequence similarities of 95.9 and 95.2 %, respectively. Strain GH29-5T was most closely related to ‘Flavobacterium saliodium’, F. denitrificans and Flavobacterium frigoris, with sequence similarities of 94.3, 92.5 and 92.5 %, respectively. The major cellular fatty acids of GH1-10T were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and iso-C17 : 0 3-OH, and those of GH29-5T were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. Both strains contained menaquinone with six isoprene units (MK-6) as the sole quinone. The DNA G+C contents of GH1-10T and GH29-5T were 35 and 39 mol%, respectively. Based on the phylogenetic and phenotypic data presented, it is concluded that the two bacteria represent two separate novel species of the genus Flavobacterium. The names proposed to accommodate these organisms are Flavobacterium daejeonense sp. nov., with type strain GH1-10T (=KACC 11422T=DSM 17708T), and Flavobacterium suncheonense sp. nov., with type strain GH29-5T (=KACC 11423T=DSM 17707T).

In the early 1980s, a facultatively anaerobic, non-motile, short rod, designated 202T, was isolated from a chicken crop and identified as a homofermentative lactic acid bacterium. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain was affiliated with the genus Lactobacillus, clustering within the Lactobacillus acidophilus–delbrueckii group. In this analysis, strain 202T appeared to be most closely related to the type strains of Lactobacillus intestinalis and Lactobacillus amylolyticus, with gene sequence similarities of 96.1 and 96.2 %, respectively. Strain 202T was found to differ from these two species, however, when investigated by multilocus sequence analysis, and it also differed in terms of some of its metabolic properties. On the basis of these observations, strain 202T is considered to represent a novel species in the genus Lactobacillus, for which the name Lactobacillus gigeriorum sp. nov. is proposed; the type strain is 202T ( = CRBIP 24.85T = DSM 23908T).

An extremely haloalkaliphilic archaeon, strain AD2T, was isolated from Aiding salt lake in Xin-Jiang, China. Strain AD2T required at least 12 % NaCl for growth. MgCl2 was not required. The isolate was able to grow over a pH range of 8.0–10.0 and temperature range of 20–55 °C, with optimal growth at pH 8.7–9.2 and 44–47 °C. The major polar lipids of strain AD2T were phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester; glycolipids were not detected. Analysis of its 16S rRNA gene sequence indicated that strain AD2T was phylogenetically related to members of the genus Natronorubrum, with sequence similarities to the type strains of Natronorubrum bangense, Natronorubrum tibetense and Natronorubrum aibiense of 97.1, 95.9 and 96.1 %, respectively. The G+C content of its DNA was 60.9 mol% (T m). Levels of DNA–DNA relatedness between strain AD2T and the type strains of Nrr. bangense, Nrr. tibetense and Nrr. aibiense were 49, 38 and 41 %, respectively. It was concluded that strain AD2T represents a novel species of the genus Natronorubrum, for which the name Natronorubrum sulfidifaciens sp. nov. is proposed. The type strain is AD2T (=CGMCC 1.6307T=JCM 14089T).

Two novel strains of Gram-negative, non-sporulating, short rod-shaped, motile bacteria, designated DCY25T and DCY28, were isolated from soil of a ginseng field in South Korea and characterized in order to determine their taxonomic position. 16S rRNA gene sequence analysis showed that strains DCY25T and DCY28 belonged to the Betaproteobacteria, the highest sequence similarities being found with Pusillimonas noertemannii BN9T (96.9 %), Bordetella trematum DSM 11334T (95.9 %), Achromobacter denitrificans DSM 30026T (95.9 %), Achromobacter insolitus LMG 6003T (95.8 %) and Pigmentiphaga kullae K24T (95.5 %). Chemotaxonomic data revealed that both strains DCY25T and DCY28 possessed ubiquinone Q-8. Fatty acid analysis of strain DCY25T demonstrated the presence of 19 : 0 cyclo ω8c (22.8 %) and 16 : 0 (16.6 %). The polar lipid profiles of strains DCY25T and DCY28 included phosphatidylethanolamine, phosphatidylglycerol, two unknown aminolipids and diphosphatidylglycerol. The G+C contents of strains DCY25T and DCY28 were 57.3 and 57.2 mol%, respectively. DNA–DNA relatedness values, biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strains DCY25T and DCY28 from Pusillimonas noertemannii. Therefore, strains DCY25T and DCY28 should be classified in a novel species, for which the name Pusillimonas ginsengisoli sp. nov. is proposed. The type strain is DCY25T (=KCTC 22046T =JCM 14767T); strain DCY28 (=KCTC 22047=JCM 14768) is a reference strain.

Seventeen anaerobic, Gram-negative, tiny coccobacilli were collected in France from various human clinical samples. Biochemical analyses as well as molecular studies, including 16S rRNA and dnaK gene sequencing, affiliated all the isolates to the genus Dialister. However, 16S rRNA and dnaK gene sequence similarities were below 95·2 and 79·7 %, respectively, when comparisons were performed with the currently described species Dialister pneumosintes and Dialister invisus. Two clusters consisting of 13 and four isolates could be differentiated. 16S rRNA- and dnaK-based phylogeny confirmed that these two clusters represent two novel and distinct lineages within the genus Dialister. Finally, phenotypic, genotypic and phylogenetic data supported the proposal of the two novel species Dialister micraerophilus sp. nov. (type strain ADV 04.01T=AIP 25.04T=CIP 108278T=CCUG 48837T) and Dialister propionicifaciens sp. nov. (type strain ADV 1053.03T=AIP 26.04T=CIP 108336T=CCUG 49291T). The G+C content of the DNA of the D. micraerophilus type strain is 36·3 mol%. On the basis of 16S rRNA gene sequence analysis, 11 isolates originating from Canada could also be affiliated to D. micraerophilus sp. nov., and were included in the species description.

Two novel actinobacteria isolates, designated YIM 70009T and YIM 70081T, were characterized in order to determine their taxonomic position. Cells of strains YIM 70009T and YIM 70081T were cocci, although only the latter were motile. The G+C contents of their DNAs were 64·0 and 64·5 mol%, respectively. On the basis of chemotaxonomic characteristics and 16S rRNA gene sequence analysis, the two isolates were classified in the genus Nesterenkonia. DNA–DNA hybridization and comparison of phenotypic characteristics revealed that strains YIM 70009T and YIM 70081T differed from each other and from known species. Therefore, it is proposed that they represent two separate novel species of the genus Nesterenkonia: Nesterenkonia sandarakina sp. nov. (type strain, YIM 70009T=CCTCC AA 203007T=DSM 15664T=KCTC 19011T) and Nesterenkonia lutea sp. nov. (type strain, YIM 70081T=CCTCC AA 203010T=DSM 15666T=KCTC 19013T).

Three bacterial strains, designated MT1T, RW10T and IpA-2T, had been isolated previously for their ability to degrade chlorosalicylates or isopimaric acid. 16S rRNA gene sequence analysis demonstrated that these bacteria are related to species of the genus Pseudomonas. Analysis of the results of DNA–DNA hybridization with several close phylogenetic neighbours revealed a low level of hybridization (less than 57 %). On the basis of phenotypic characteristics, phylogenetic analysis, DNA–DNA relatedness data and chemotaxonomic analysis, it is concluded that these isolates represent separate novel species, for which the names Pseudomonas reinekei sp. nov. (type strain MT1T =DSM 18361T=CCUG 53116T), Pseudomonas moorei sp. nov. (type strain RW10T =DSM 12647T=CCUG 53114T) and Pseudomonas mohnii sp. nov. (type strain IpA-2T =DSM 18327T=CCUG 53115T) are proposed.

A taxonomic study of a novel marine, heterotrophic, non-gliding, halotolerant and light-pink-pigmented bacterium was carried out using a polyphasic approach. 16S rRNA gene sequence analysis revealed that strain KMM 6241T is a member of the phylum Bacteroidetes. Strain KMM 6241T formed a cluster with the genera Algoriphagus, Chimaereicella and Hongiella with sequence similarities of 94.0–98.2 %. Hongiella ornithinivorans was the closest relative of the novel isolate. Comparative analysis of phenotypic, chemotaxonomic and genotypic characteristics of strain KMM 6241T and representatives of the genera Algoriphagus, Chimaereicella and Hongiella revealed many similar features. Consequently, phylogenetic evidence supported by phenotypic and genotypic similarities support the transfer of members of the genera Chimaereicella and Hongiella to the genus Algoriphagus and the establishment of a novel species, Algoriphagus vanfongensis sp. nov., with strain KMM 6241T (=DSM 17529T=KCTC 12716T) as the type strain.

A Gram-negative, aerobic, rod-shaped, non-motile bacterium, designated BZ42T, was isolated from the soil of an industrial site. Strain BZ42T was able to grow at 5–25 °C. The major fatty acids were iso-C15 : 0 (46.2 %), C16 : 1 ω7c and/or iso-C15 : 0 2-OH (23.2 %) and iso-C17 : 0 3-OH (9.1 %). The predominant menaquinone was MK-7. The genomic DNA G+C content was 36.5 mol% (HPLC). 16S rRNA gene sequence phylogenetic analysis revealed that strain BZ42T was a member of the genus Pedobacter, family Sphingobacteriaceae, and 16S rRNA gene sequence similarities between strain BZ42T and the type strains of species of the genus Pedobacter with validly published names were 90.4–93.2 %. On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain BZ42T was considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter bauzanensis sp. nov. is proposed. The type strain is BZ42T (=DSM 22554T =CGMCC 1.10187T =CIP 110134T).
