A Gram-negative, rod-shaped bacterial strain, designated K19414T, was isolated from a chironomid (Diptera; Chironomidae) egg mass which was sampled from Kishon River in northern Israel. Phylogenetic analysis based on the 16S rRNA gene sequence positioned the novel strain among the genus Rheinheimera, with closest similarity to Rheinheimera pacifica KMM 1406T. The levels of similarity to type strains of Rheinheimera species were lower than 96.5 %. Isolate K19414T is aerobic, motile by means of a single polar flagellum, catalase-negative and oxidase-positive; growth was observed at salinities of 0–2 % NaCl and the temperature for growth ranged from 4 to 40 °C. The major cellular fatty acids are 16 : 0 (14.8 %) and 16 : 1ω7c and/or 15 : 0 iso 2-OH (25.76 %). The DNA G+C content is 49.9 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain K19414T (=LMG 23818T =DSM 18694T) was classified in the genus Rheinheimera as the type strain of a novel species, for which the name Rheinheimera chironomi sp. nov. is proposed.

The 16S Rrna Gene

A Gram-negative, non-motile, coccobacilli-shaped bacterium, DS-48T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by means of a polyphasic study. Strain DS-48T grew optimally at 25 °C and pH 7.0–8.0 in the presence of 0.5 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C18 : 1 ω7c and C18 : 1 2-OH as the major fatty acids. The DNA G+C content was 69.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-48T fell within the genus Roseomonas, clustering with Roseomonas lacus TH-G33T (at a bootstrap confidence level of 100 %). The levels of similarity between the 16S rRNA gene sequence of strain DS-48T and those of the type strains of recognized Roseomonas species were in the range 93.2–98.0 %. DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness of DS-48T, revealed that this strain differs from recognized Roseomonas species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain DS-48T represents a novel species within the genus Roseomonas, for which the name Roseomonas terrae sp. nov. is proposed. The type strain is DS-48T (=KCTC 12874T=JCM 14592T).

A Gram-negative, non-sporulating, non-flagellated rod, designated BR-9T, was isolated from soil collected on the Korean peninsula. Strain BR-9T grew optimally at pH 6.0–7.0, at 30 °C and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BR-9T belonged to the genus Pedobacter and clustered with Pedobacter insulae DS-139T and Pedobacter koreensis WPCB189T. Strain BR-9T exhibited 98.2 and 97.5 % 16S rRNA gene sequence similarity with P. insulae DS-139T and P. koreensis WPCB189T, respectively, and <96.7 % sequence similarity with the type strains of other species in the genus Pedobacter. Strain BR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C content of strain BR-9T was 38.5 mol%. DNA–DNA relatedness between strain BR-9T and P. insulae DS-139T and P. koreensis KCTC 12536T was 3.4–4.2 %, which indicated that the isolate was genetically distinct from these type strains. Strain BR-9T was also distinguishable by differences in phenotypic properties. On the basis of the data presented, strain BR-9T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter boryungensis sp. nov. is proposed. The type strain is BR-9T ( = KCTC 23344T  = CCUG 60024T).

Three Gram-positive-staining strains isolated from fermented stinky tofu brine were rod-shaped, non-motile, asporogenous, facultatively anaerobic, heterofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, rpoA and pheS gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus collinoides (98.6 %), Lactobacillus paracollinoides (98.6 %) and Lactobacillus similis (99.6 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 10 %. The phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus odoratitofui sp. nov. is proposed. The type strain is YIT 11304T (=JCM 15043T =BCRC 17810T =DSM 19909T).

A dark-pink-coloured bacterial strain, B4Y-8T, was isolated from a soil cultivated with ginseng. The 16S rRNA gene sequence of this strain showed highest similarity with Mucilaginibacter litoreus BR-18T (96.8 %), Mucilaginibacter lutimaris BR-3T (96.6 %) and Mucilaginibacter defluvii A5T (96.2 %) among the type strains of species of the genus Mucilaginibacter. Strain B4Y-8T was a strictly aerobic, Gram-stain-negative, non-motile, short-rod-shaped bacterium producing a large amount of extracellular polymeric substance. The strain grew at 10–35 °C (optimum, 25 °C), at pH 3.0–11.0 (optimum, pH 7.0) and in the presence of 0–1 % (w/v) NaCl (optimum, 0 %). The DNA G+C content of strain B4Y-8T was 49.0 mol%. It contained menaquinone 7 (MK-7) as the major isoprenoid quinone, and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and iso-C15 : 0 as the major fatty acids. On the basis of evidence from the present polyphasic taxonomic study, strain B4Y-8T should be classified as representing a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter ginsengisoli sp. nov. is proposed. The type strain is B4Y-8T ( = KACC 18152T = JCM 30759T).

A polyphasic study was undertaken to establish the taxonomic status of a Gram-positive, aerobic actinomycete, strain HPA177T, isolated from a marine sponge, Hymeniacidon perleve. The organism formed branching, non-fragmenting vegetative hyphae and produced black pigment. Chemotaxonomic characteristics were consistent with its assignment to the genus Actinoalloteichus. Analysis of the 16S rRNA gene sequence showed that strain HPA177T formed a robust clade with type strains of the genus Actinoalloteichus, but was distinct from them. A number of phenotypic characteristics also readily distinguished strain HPA177T from species of the genus Actinoalloteichus with validly published names. On the basis of the above data, it is proposed that strain HPA177T represents a novel species, Actinoalloteichus hymeniacidonis sp. nov. The type strain of Actinoalloteichus hymeniacidonis is HPA177T (=CGMCC 4.2500T=JCM 13436T).

Three Gram-stain-positive strains were isolated from fermented mustard and were rod-shaped, non-motile, asporogenous, facultatively anaerobic, homofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, pheS and rpoA gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence analysis, the type strains of Lactobacillus crustorum (98.7 % similarity), Lactobacillus farciminis (98.9 %) and Lactobacillus mindensis (97.9 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 50 %. Phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus futsaii sp. nov. is proposed; the type strain is YM 0097T ( = JCM 17355T = BCRC 80278T).

Relatedness Data

A novel nitrate-reducing bacterium, CPW406T, was isolated from the sediment of a shallow, freshwater lake. The strain was a Gram-negative, non-motile, non-spore-forming rod, which formed yellow-pigmented colonies on nutrient agar and contained a polyamine pattern with sym-homospermidine as the major compound, MK-6 as the predominant menaquinone, 15 : 0 iso and 17 : 0 iso 3-OH as the major fatty acids and phosphatidylethanolamine and several unknown lipids in the polar lipid profile. The 16S rRNA gene sequence of strain CPW406T was found to be most similar to that of the type strain of Chryseobacterium defluvii (DSM 14219T; 97·9 % similarity). However, DNA–DNA relatedness data and its phenotypic properties showed that strain CPW406T could be distinguished from all known Chryseobacterium species and thus represented a novel species, for which the name Chryseobacterium daecheongense sp. nov. is proposed; the type strain is CPW406T (=DSM 15235T=KCTC 12088T).

Sequence Similarities

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).

The taxonomic position of an actinomycete isolated from a brown hypermagnesian ultramafic soil was examined using a polyphasic approach. The organism, which was designated SBHS Strp1T, was found to have chemical and morphological properties typical of Amycolatopsis strains. It was most closely associated with Amycolatopsis kentuckyensis, Amycolatopsis lexingtonensis, Amycolatopsis rifamycinica, Amycolatopsis pretoriensis and Amycolatopsis tolypomycina on the basis of 16S rRNA gene sequence data, and showed a unique pattern of phenotypic properties that distinguished it from the type strains of these taxa. The combined genotypic and phenotypic data show that the organism merits description as a novel species of Amycolatopsis. The name proposed for the novel species is Amycolatopsis plumensis sp. nov.; the type strain is SBHS Strp1T (=DSM 44776T=NRRL B-24324T).
