Major Isoprenoid Quinone

A non-motile, rod-shaped bacterium, designated strain WPCB133T, was isolated from freshwater collected from the Woopo wetland (Republic of Korea). Cells were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The strain contained MK-7 as the major isoprenoid quinone. The DNA G+C content was 47 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WPCB133T forms an independent lineage within the genus Mucilaginibacter. Strain WPCB133T was distantly related to Mucilaginibacter kameinonensis SCKT (94.7 % sequence similarity), Mucilaginibacter paludis TPT56T (94.5 %) and Mucilaginibacter gracilis TPT18T (94.4 %). Phenotypic characteristics distinguished strain WPCB133T from members of the genus Mucilaginibacter. On the basis of evidence presented in this study, strain WPCB133T represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter rigui sp. nov. is proposed. The type strain is WPCB133T (=KCTC 12534T =NBRC 101115T). An emended description of the genus Mucilaginibacter is also proposed.

A yellow-coloured bacterium, T41T, was isolated from a soil sample of a subtropical rainforest in Nepal. Cells were Gram-reaction-positive, aerobic, non-motile, short rods. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain formed a cluster with Terrimonas ferruginea, Terrimonas lutea, Niabella soli, Flavisolibacter ginsengiterrae, Flavisolibacter ginsengisoli, Niastella yeongjuensis and Niastella koreensis in the phylum Bacteroidetes. The strain showed the highest sequence similarity to the type strain of Terrimonas lutea (93.2 %). The major isoprenoid quinone was MK-7 and the predominant cellular fatty acids (>10 %) were iso-15 : 0 (33.8 %), iso-15 : 1 G (13.3 %) and iso-17 : 0 3-OH (12.9 %). The DNA G+C content was 48.1 mol%. On the basis of phenotypic and phylogenetic data and genomic distinctiveness, strain T41T represents a novel species in a new genus in the phylum Bacteroidetes, for which the name Flavihumibacter petaseus gen. nov., sp. nov. is proposed.

A non-motile and rod-shaped bacterium, designated strain 02SUJ3T, was isolated from freshwater collected from the Juam Reservoir (Republic of Korea). Cells were Gram-stain-negative, aerobic, oxidase-negative and catalase-positive. The major fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The strain contained MK-7 as the major isoprenoid quinone. The main polar lipid was phosphatidylethanolamine. The DNA G+C content was 46.4 mol%.

A marine bacterial strain, FR1064T, was isolated from a surface seawater sample collected off Jeju Island, South Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the Gammaproteobacteria and was related to the genus Glaciecola with 97.6 % sequence similarity to Glaciecola pallidula, its nearest phylogenetic neighbour. DNA–DNA relatedness between strain FR1064T and G. pallidula ACAM 615T was 55 %. Cells of the novel isolate were Gram-negative, aerobic, rod-shaped, motile and halophilic, with an optimum sea salts concentration of 4–7 %. The major fatty acids were straight-chain saturated (C16 : 0), summed feature 3 and monounsaturated fatty acid C18 : 1. The DNA G+C content was 44 mol%. Several phenotypic characteristics differentiated the novel isolate from all previously described members of the genus Glaciecola. The polyphasic data obtained in this study clearly demonstrate that strain FR1064T represents a novel species of the genus Glaciecola. The name Glaciecola nitratireducens sp. nov. is therefore proposed, with strain FR1064T (=KCTC 12276T=JCM 12485T) as the type strain.

A non-motile and rod-shaped bacterium, designated strain WM78T, was isolated from freshwater collected from the Woopo wetland (Republic of Korea). Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were iso-C15 :0, anteiso-C15 :0, C16 :1ω7c and/or C16 :1ω6c and iso-C17 :1 I and/or anteiso-C17 :1 B. The strain contained MK-7 as the major isoprenoid quinone, phosphatidylethanolamine as the major polar lipid and sym-homospermidine as the major polyamine. The genomic DNA G+C content was 62 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WM78T forms evolutionary lineage within the radiation comprising members of the genus Hymenobacter with Hymenobacter gelipurpurascens Txg1T (97.7 % sequence similarity) as its nearest neighbour. A number of phenotypic characteristics distinguished strain WM78T from related members of the genus Hymenobacter. The evidence presented in this study support the designation of strain WM78T as a representative of a novel species in the genus Hymenobacter for which the name Hymenbactor wooponensis sp. nov. is proposed. The type strain is WM78T ( = KCTC 32528T = JCM 19491T).

Relatedness Data

A non-motile, rod-shaped, light-yellow-pigmented bacterium, designated strain WPCB159T, was isolated from freshwater samples collected from the Woopo wetland in Korea. The cells were Gram-negative, aerobic and catalase- and oxidase-positive. The major fatty acids were C16 : 1 ω7c (34.8 %), iso-C15 : 0 (24.2 %) and C16 : 0 (9.4 %). The DNA G+C content was 44 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WPCB159T forms a lineage within the genus Dyadobacter (family ‘Flexibacteraceae’) and is closely related to Dyadobacter hamtensis HHS 11T (97.8 % sequence similarity) and to other members of the genus Dyadobacter (95.2–96.8 % sequence similarity). The phenotypic characteristics and DNA–DNA hybridization relatedness data indicate that strain WPCB159T should be distinguished from D. hamtensis HHS 11T. On the basis of the evidence presented in this study, strain WPCB159T represents a novel species of the genus Dyadobacter, for which the name Dyadobacter koreensis sp. nov. is proposed. The type strain is WPCB159T (=KCTC 12537T=NBRC 101116T).

A Gram-positive, aerobic, non-motile, rod-shaped, spore-forming bacterium, designated Gsoil 139T, was isolated from soil from a ginseng field in Pocheon Province, South Korea, and was characterized using a polyphasic approach. Comparative analysis of 16S rRNA gene sequences revealed that strain Gsoil 139T belongs to the family Paenibacillaceae. The greatest sequence similarity was found with respect to the type strains of Paenibacillus hodogayensis (95.6 %) and Paenibacillus koleovorans (93.8 %). The strain showed less than 93.8 % sequence similarity with respect to other species of the genus Paenibacillus. The G+C content of the genomic DNA was 48.1 mol%. In addition, the presence of MK-7 as the major menaquinone and C15 : 0 anteiso as a major fatty acid (27.9 %) justifies its affiliation to the genus Paenibacillus. On the basis of its phenotypic characteristics and phylogenetic distinctiveness, strain Gsoil 139T represents a novel species within the genus Paenibacillus, for which the name Paenibacillus ginsengarvi sp. nov. is proposed. The type strain is Gsoil 139T (=KCTC 13059T =DSM 18677T).
