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.

Gene Sequence Analysis

Strain DSM 44594T, which produces the glycopeptide antibiotic decaplanin, is a member of the genus Amycolatopsis based on 16S rRNA gene sequence analysis and chemotaxonomic properties. It is the first member of this genus that is reported to form pseudosporangia, which resemble those of members of the genus Kibdelosporangium. Phylogenetically, the novel taxon is related to Amycolatopsis orientalis, Amycolatopsis lurida, Amycolatopsis azurea, Amycolatopsis japonica and Amycolatopsis keratiniphila. Morphological, cultural and physiological properties, the production of a unique glycolipid and DNA–DNA similarity of <55 % with phylogenetically related strains reveal that strain DSM 44594T represents a novel species of the genus, for which the name Amycolatopsis decaplanina sp. nov. (type strain, FH 1845T=DSM 44594T=NRRL B-24209T) is proposed.

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).

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).

Two strains of anaerobic, Gram-stain-negative bacilli isolated from the human oral cavity (D033B-12-2T and D080A-01) were subjected to a comprehensive range of phenotypic and genotypic tests and were found to be distinct from any previously described species. 16S rRNA gene sequence analysis revealed that the strains were related most closely to the type strain of Prevotella marshii (93.5 % sequence identity). The novel strains were saccharolytic and produced acetic acid and succinic acid as end products of fermentation. The principal cellular long-chain fatty acids were C16 : 0, iso-C14 : 0, C14 : 0, anteiso-C15 : 0, iso-C16 : 0 and C16 : 0 3-OH. The G+C content of the DNA of strain D033B-12-2T was 44 mol%. Strains D033B-12-2T and D080A-01 are considered to represent a single novel species of the genus Prevotella, for which the name Prevotella saccharolytica sp. nov. is proposed. The type strain is D033B-12-2T (=DSM 22473T =CCUG 57944T).

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.

Two Gram-negative, vibrioid, phototrophic, purple non-sulfur strains, JA131T and JA135T, were isolated from marine habitats. Strain JA131T is non-motile but strain JA135T is motile by means of a pair of monopolar flagella. Both strains have an obligate requirement for NaCl for growth. The intracellular photosynthetic membranes of the two novel strains are of the vesicular type. Bacteriochlorophyll a and probably rhodovibrine are present as photosynthetic pigments. Niacin, thiamine and p-aminobenzoic acid are required as growth factors for both novel strains. Based on 16S rRNA gene sequence analysis, morphological and physiological characteristics, strains JA131T and JA135T are significantly different from each other and from other species of the genus Roseospira and thus represent two novel species for which the names Roseospira visakhapatnamensis sp. nov. and Roseospira goensis sp. nov. are proposed, respectively. The type strain of Roseospira visakhapatnamensis sp. nov. is JA131T (=ATCC BAA-1365T=JCM 14190T) and the type strain of Roseospira goensis sp. nov. is JA135T (=ATCC BAA-1364T=JCM 14191T).

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.
