A yellow-pigmented, Gram-negative, short rod-shaped, non-motile and non-spore-forming bacterial strain, designated HU1-AH51T, was isolated from freshwater sediment and was characterized using a polyphasic approach, in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain HU1-AH51T was shown to belong to the genus Novosphingobium, showing the highest level of sequence similarity with respect to Novosphingobium resinovorum NCIMB 8767T (96.0 %), Novosphingobium naphthalenivorans TUT562T (96.0 %) and Novosphingobium panipatense SM16T (96.0 %). Strain HU1-AH51T had a genomic DNA G+C content of 62.6 mol% and Q-10 as the predominant respiratory quinone. Furthermore, the major polyamine component (spermidine) in the cytoplasm and the presence of sphingoglycolipids suggested that strain HU1-AH51T belongs to the family Sphingomonadaceae. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain HU1-AH51T represents a novel species of the genus Novosphingobium, for which the name Novosphingobium sediminicola sp. nov. is proposed. The type strain is HU1-AH51T ( = LMG 24320T  = KCTC 22311T).

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

Ginseng Cultivation

A Gram-reaction-negative, aerobic, non-motile and rod-shaped bacterial strain designated Gsoil 636T was isolated from soil of a ginseng cultivation field in Pocheon Province, South Korea and its taxonomic position was investigated using a polyphasic approach. Gsoil 636T grew at 18–30 °C and at pH 6.0–8.0 on R2A medium. Gsoil 636T possessed β-glucosidase activity, which was responsible for its ability to transform ginsenoside Rb1 (ones of the dominant active components of ginseng) to F2. On the basis of 16S rRNA gene sequence similarity, Gsoil 636T was shown to belong to the family Chitinophagaceae and to be related to Flavisolibacter ginsengiterrae Gsoil 492T (96.7 % sequence similarity), Flavisolibacter ginsengisoli Gsoil 643T (96.6 %) and Flavisolibacter rigui 02SUJ3T (96.6 %). The G+C content of the genomic DNA was 48.9 %. The predominant respiratory quinone was MK-7 and the major fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH. DNA and chemotaxonomic data supported the affiliation of Gsoil 636T to the genus Flavisolibacter. Gsoil 636T could be differentiated genotypically and phenotypically from the species of the genus Flavisolibacter with validly published names. The isolate therefore represents a novel species, for which the name Flavisolibacter ginsenosidimutans sp. nov. is proposed, with the type strain Gsoil 636T (KCTC 22818T = JCM 18197T = KACC 14277T).

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.

Two Gram-negative, motile, aerobic bacterial strains, designated B2T and 1_C16_27T, were respectively isolated from a seawater sample collected from the East China Sea and a semi-coke sample from north-eastern Estonia. Their genetic, phenotypic and chemotaxonomic properties were studied. The isolates were short rods with polar flagella and were positive for catalase and oxidase activities. Q-10 was the predominant respiratory ubiquinone. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and two unidentified glycolipids. The major fatty acids were nonadecanoic (C19 : 0 cyclo), octadecanoic (C18 : 0 and C18 : 0 3-OH), octadecenoic (C18 : 1) and hexadecanoic (C16 : 0) acids. The G+C content of the genomic DNA was 58.1–59.3 mol%. 16S rRNA gene sequence analysis revealed that the two isolates represent a distinct lineage within the family Hyphomicrobiaceae. The phylogenetically closest relatives were Cucumibacter (92.7–93.7 % 16S rRNA gene sequence similarity), Devosia (92.9–94.4 %) and Zhangella (91.7–92.1 %). Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strains B2T and 1_C16_27T could be differentiated from each other and from members of the genera Cucumibacter, Devosia and Zhangella. Therefore, it is proposed that strains B2T and 1_C16_27T represent two novel species in a new genus, for which the names Pelagibacterium halotolerans gen. nov., sp. nov. (the type species; type strain B2T  = CGMCC 1.7692T  = JCM 15775T) and Pelagibacterium luteolum sp. nov. (type strain 1_C16_27T  = CGMCC 1.10267T  = JCM 16552T  = CELMS EEUT 1C1627T) are proposed.
