A Gram-negative, non-motile, rod-shaped bacterial strain, designated CW-E 2T, was isolated from a polluted soil sample collected from Jiangsu Province, China. A taxonomic study of the isolate, including phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics, was carried out. The predominant menaquinone was MK-6 and the major fatty acids were i-C15 : 0, i-C17 : 0 3-OH, i-C17 : 1 ω9c and summed feature 4. The G+C content of the DNA was 37.2 mol%. Based on phenotypic and genotypic characteristics, strain CW-E 2T represents a novel species of the genus Chryseobacterium for which the name Chryseobacterium flavum sp. nov. is proposed. The type strain is CW-E 2T (=KCTC 12877T=CCTCC AB 206147T).

A motile, rod-shaped bacterium, designated strain WPCB189T, was isolated from fresh water collected from the Woopo wetland (Republic of Korea). The cells were found to be Gram-negative, aerobic and catalase- and oxidase-positive. A phylogenetic analysis based on 16S rRNA gene sequences showed that this isolate forms a lineage within the genus Pedobacter, showing sequence similarities of 89.7–96.4 % with respect to recognized species of the genus, and represents a novel member of this genus. The major fatty acids were iso-C15 : 0 2-OH and/or C16 : 1 ω7c (summed feature 3, 29.7 %), iso-C15 : 0 (26.4 %) and iso-C17 : 1 3-OH (10.1 %). The DNA G+C content was 38.0 mol%. On the basis of data obtained from this polyphasic taxonomic study, strain WPCB189T represents a novel species of the genus Pedobacter, for which the name Pedobacter koreensis sp. nov. is proposed. The type strain is WPCB189T (=KCTC 12536T=NBRC 101153T).

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.

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.

Phenotypic Features

Halorubrum distributum (basonym, Halobacterium distributum) is an extremely halophilic, aerobic archaeon isolated from saline soils, which was described on the basis of phenotypic features of several strains. The designated type strain of the species (1mT=VKM B-1733T=JCM 9100T) was shown recently to differ from the other strains. In this study, Halorubrum distributum isolates have been characterized with regard to phenotypic features, polar lipid content, comparison of 16S rRNA gene sequences and DNA–DNA hybridization. On the basis of these data, a novel species that includes the other isolates is proposed, with the name Halorubrum terrestre sp. nov. The type strain of this novel species is 4pT (=VKM B-1739T=JCM 10247T). The DNA G+C content of this novel species is 64·2–64·9 mol% (64·4 mol% for the type strain).

A novel, non-pigmented, rod-shaped, Gram-negative strain was isolated from mesotrophic lake water in Zealand, Denmark. Phylogenetic analysis of the 16S rRNA gene sequence of the bacterium, designated strain 389T, indicated that the strain belonged to the genus Vogesella and formed a monophyletic group with Vogesella perlucida DS-28T (99.1 % nucleotide similarity); it was less related to Vogesella indigofera ATCC 19706T (96.9 % similarity) and Vogesella lacus LMG 24504T (96.8 % similarity). Hybridization of DNA from strain 389T and V. perlucida demonstrated a reassociation of 50.6±9.6 %. The DNA G+C content of strain 389T was 61.2 mol%. The fatty acid profile of the strain differed from those of the other strains representing the genus Vogesella by a high content of C16 : 1 ω7c and/or iso-C15 : 0 2-OH (71.6 %) and a lower content of C16 : 0. Strain 389T was capable of degrading peptidoglycan and had chitinase and lysozyme activities, possibly associated with the degradation of peptidoglycan, and had capacity for degradation of several other polymer compounds. Based on phenotypic and genotypic characteristics, strain 389T represents a novel species, for which we propose the name Vogesella mureinivorans sp. nov. The type strain is 389T (=DSM 21247T =LMG 25302T).

A Gram-negative, rod-shaped, motile, non-spore-forming bacterium, designated strain A62-14BT, was isolated from a constant-temperature, spring-fed, freshwater lake. On the basis of the complete 16S rRNA gene sequence, strain A62-14BT was shown to belong to the class Gammaproteobacteria, being most closely related to Rheinheimera sp. HTB082 (96.2 % sequence similarity), Rheinheimera baltica (95.01 %), Rheinheimera pacifica (96.35 %), Rheinheimera perlucida and Alishewanella fetalis (95.9 %). The major fatty acids (C16 : 1 ω7c, 38.56 %; C16 : 0, 19.04 %; C12 : 0 3-OH, 12.83 %; C18 : 1 ω7c, 7.70 %) and the motility of strain A62-14BT support its affiliation to the genus Rheinheimera. The salt intolerance of strain A62-14BT, together with the results of other physiological and biochemical tests, allowed the differentiation of this strain from the three species of the genus Rheinheimera with validly published names. Therefore strain A62-14BT represents a novel species of the genus Rheinheimera, for which the name Rheinheimera texasensis sp. nov. is proposed. The type strain is A62-14BT (=ATCC BAA-1235T=DSM 17496T). The description of the genus Rheinheimera is emended to reflect the halointolerance and freshwater origin of strain A62-14BT.
