A bacterial strain (CC-TWGS1-8T) isolated from a tar-contaminated soil in Taiwan was studied in a detailed taxonomic study. The cells were Gram-negative, rod-shaped and non-spore-forming. Phylogenetic analyses using the 16S rRNA gene sequence of the strain clearly revealed an affiliation to the genus Chryseobacterium, the highest sequence similarities being to the type strain of Chryseobacterium indologenes (96·8 %), to Chryseobacterium gleum (96·8 %) and to Chryseobacterium joostei (96·4 %). The 16S rRNA gene sequence similarities to all other Chryseobacterium species were below 96 %. The major whole-cell fatty acids were 15 : 0 iso (35·4 %) and 17 : 0 iso 3OH (22·5 %). DNA–DNA hybridization values and the biochemical and chemotaxonomic properties demonstrate that strain CC-TWGS1-8T represents a novel species, for which the name Chryseobacterium taichungense sp. nov. is proposed. The type strain is CC-TWGS1-8T (=CCUG 50001T=CIP 108519T).

Sequence Similarities

Four Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile strains (Y26, Y57T, ZJ14WT and RP18W) were isolated from mariculture fishponds in PR China. Comparisons based on 16S rRNA gene sequences showed that strains Y26 and Y57T share 16S rRNA gene sequence similarities in the range of 95.1−98.5 % with species of the genus Bowmanella , and strains ZJ14WT and RP18W share 16S rRNA gene sequence similarities in the range of 96.7 −98.8 % with species of the genus Amphritea , respectively. The genome sizes of strains Y26, Y57T, ZJ14WT and RP18W were about 4.85, 5.40, 4.70 and 4.70 Mbp with 49.5, 51.7, 51.2 and 51.3 mol% G+C content, respectively. The calculated pairwise OrthoANIu values among strains Y26, Y57T and species of the genus Bowmanella were in the range of 72.6−83.1 %, but the value between strains Y26 and Y57T was 96.2 %. The pairwise OrthoANIu values among strains ZJ14WT, RP18W and other species of the genus Amphritea were all less than 93.9 %, but the value between strains ZJ14WT and RP18W was 99.3 %. Q-8 was the major respiratory quinone of strains Y26, Y57T, ZJ14WT and RP18W, and the major fatty acids of these strains were all C16 : 1 ω7c, C16 : 0 and C18 : 1 ω7c. The predominant polar lipids of strains Y26 and Y57T included phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylinositol, but strains ZJ14WT and RP18W only contained phosphatidylethanolamine and phosphatidylglycerol. Combining phenotypic, biochemical and genotypic characteristics, strains Y26 and Y57T should belong to the same species and represent a novel member of the genus Bowmanella , and strains ZJ14WT and RP18W should belong to the same species and represent a novel member of the genus Amphritea , for which the names Bowmanella yangjiangensis sp. nov. (type strain Y57T=GDMCC 1.2180T=KCTC 82439T) and Amphritea pacifica sp. nov. (type strain ZJ14WT=GDMCC 1.2203T=KCTC 82438T) are proposed.

Two strains, KBL13T and GBL13, were isolated as one of intestinal lactobacilli from the faecal specimens from different thoroughbreds of the same farm where they were born in Hokkaido, Japan. They were Gram-positive, facultatively anaerobic, catalase-negative, non-spore-forming and non-motile rods. KBL13T and GBL13 homofermentatively metabolize glucose, and produce lactate as the sole final product from glucose. The 16S rRNA gene sequence, DNA–DNA hybridization, DNA G+C content and biochemical characterization indicated that these two strains, KBL13T and GBL13, belong to the same species. In the representative strain, KBL13T, the DNA G+C content was 34.3 mol%. Lactobacillus salivarius JCM 1231T (=ATCC 11741T; AF089108) is the type strain most closely related to the strain KBL13T as shown in the phylogenetic tree, and the 16S rRNA gene sequence identity showed 96.0 % (1425/1484 bp). Comparative 16S rRNA gene sequence analysis of this strain indicated that the two isolated strains belong to the genus Lactobacillus and that they formed a branch distinct from their closest relatives, L. salivarius, Lactobacillus aviarius, Lactobacillus saerimneri and Lactobacillus acidipiscis. DNA–DNA reassociation experiments with L. salivarius and L. aviarius confirmed that KBL13T represents a novel species, for which the name Lactobacillus hayakitensis sp. nov. is proposed. The type strain is KBL13T (=JCM 14209T=DSM 18933T).

A Gram-negative, short rod-shaped micro-organism (CC-BB4T) was isolated on nutrient agar from soil from Sinshe in Taichung County, Taiwan. Analysis of the 16S rRNA gene sequence demonstrated that this isolate was novel, as it showed <92 % similarity to the sequences of species of the genera Labrys, Beijerinckia and Methylocystis. The micro-organism did not utilize methylamine or methanol as a substrate, but was able to use several organic acids. The fatty acid profile was different from those reported for the genera Labrys, Beijerinckia, Methylocystis, Angulomicrobium, Methylorhabdus and Methyloarcula. On the basis of the 16S rRNA gene sequence analysis, in combination with chemotaxonomic and physiological data, strain CC-BB4T represents a novel genus, for which the name Pseudolabrys gen. nov. is proposed. The type species is Pseudolabrys taiwanensis sp. nov., and the type strain of P. taiwanensis is CC-BB4T (=CCUG 51779T=CIP 108932T).

A yellow, nitrogen-fixing bacterial strain, NXU-44T, isolated from the rhizosphere of switchgrass (Panicum virgatum) in Auburn, Alabama, USA, was studied to determine its taxonomic position. Cells of the isolate were rod-shaped and Gram-stain-negative. A comparison of the 16S rRNA gene sequence with the sequences of the type strains of the most closely related species showed that the strain belongs to the genus Flavobacterium with highest sequence similarities to the type strains of Flavobacterium ginsenosidimutans (97.9 %), Flavobacterium phragmitis (97.6 %) and Flavobacterium anhuiense (97.5 %). The 16S rRNA gene sequence similarities to all other species of the genus Flavobacterium were below 97.5 %. The fatty acid profile of strain NXU-44T consisted of the major fatty acids iso-C15 : 0, iso-C15 : 0 2-OH/C16 : 1ω7c and iso-C17 : 0 3-OH. The major compounds in the polar lipid profile were phosphatidylethanolamine, phosphatidylserine, one aminolipid and two polar lipids. The quinone system was composed exclusively of menaquinone MK-6. The polyamine pattern contained the major compound sym-homospermidine and only minor amounts of other polyamines. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. These data and the differential biochemical and chemotaxonomic properties show that strain NXU-44T represents a novel species of the genus Flavobacterium for which the name Flavobacterium nitrogenifigens sp. nov. is proposed. The type strain is NXU-44T ( = LMG 28694T = CIP 110894T).

A Gram-negative, aerobic, halophilic bacterium, designated strain Iso 3T, was isolated from the East Sea in Korea. Strain Iso 3T was motile by means of polar flagella, occasionally formed rosette-like aggregates and contained 18 : 1ω7c as the dominant cellular fatty acid. Strain Iso 3T grew at NaCl concentrations of 1–10 % and temperatures of 4–30 °C. The optimal growth temperature was 20 °C. Analysis of the 16S rRNA gene sequence revealed that this strain is affiliated with a subcluster of the Alphaproteobacteria. However, strain Iso 3T generated metabolic energy by sulfide oxidation. The 16S rRNA gene sequence similarity between strain Iso 3T and the type strain of the most closely related species, Sulfitobacter pontiacus, was 97.7 %. DNA–DNA relatedness between strain Iso 3T and Sulfitobacter pontiacus DSM 10014T was 24.1 %. On the basis of phenotypic properties and phylogenetic distinctiveness, strain Iso 3T is classified within a novel Sulfitobacter species, for which the name Sulfitobacter litoralis sp. nov. is proposed, with the type strain Iso 3T (=KCTC 12521T=DSM 17584T).

Chryseobacterium Gleum

A bacterial strain (CC-VM-7T), isolated from the faeces of the pill millipede Arthrosphaera magna Attems collected in India, was studied to determine its taxonomic allocation. Cells stained Gram-negative and were rod-shaped. Comparative analyses of the 16S rRNA gene sequence of the strain with those of the most closely related species clearly suggested allocation to the genus Chryseobacterium, with the highest sequence similarities of 99.2 % to Chryseobacterium gleum CCUG 14555T, 98.6 % to Chryseobacterium indologenes CCUG 14556T and 98.4 % to Chryseobacterium aquifrigidense KCTC 12894T. 16S rRNA gene sequence similarities to all other species of the genus Chryseobacterium were below 98 %. The major whole-cell fatty acids were iso-C15 : 0 and iso-C17 : 1 ω9c. DNA–DNA hybridization resulted in relatedness values of only 29.6 % (reciprocal 31.3 %) to Chryseobacterium gleum CCUG 14555T, 41.2 % (reciprocal 38.8 %) to C. indologenes CCUG 14556T and 35.4 % (reciprocal 38.5 %) to C. aquifrigidense KCTC 12894T. DNA–DNA relatedness, biochemical and chemotaxonomic properties clearly show that strain CC-VM-7T represents a novel species, for which the name Chryseobacterium arthrosphaerae sp. nov. is proposed. The type strain is CC-VM-7T (=CCUG 57618T =CCM 7645T).

A yellow-pigmented bacterial strain, 91A-612T, isolated from the geocarposphere (soil around the peanut) of very immature peanuts (Arachis hypogaea) in Alabama, USA, was studied for its taxonomic position. Cells of the isolate were rod-shaped and stained Gram-negative. A comparison of the 16S rRNA gene sequence with the sequences of the type strains of the most closely related species showed that the strain belongs to the genus Chryseobacterium, showing the highest sequence similarities to the type strains of Chryseobacterium molle (98.4 %), C. pallidum (98.3 %) and C. hominis (97.8 %). The 16S rRNA gene sequence similarities to the type strains of all other species of the genus Chryseobacterium were below 97.0 %. The fatty acid profile of strain 91A-612T consisted of the major fatty acids iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH/C16 : 1ω7c) and iso-C17 : 0 3-OH. Major compounds in the polar lipid profile were phosphatidylethanolamine and several unidentified lipids, including two lipids that did not contain a sugar moiety, an amino group or a phosphate group (L3, L8), and an aminolipid (AL1). The quinone system was composed mainly of MK-6. The polyamine pattern contained sym-homospermidine as the major compound and moderate amounts of spermidine and spermine. DNA–DNA hybridizations between strain 91A-612T and the type strains of C. molle, C. pallidum and C. hominis resulted in relatedness values well below 70 %. These data and the differentiating biochemical and chemotaxonomic properties showed that isolate 91A-612T represents a novel species of the genus Chryseobacterium, for which we propose the name Chryseobacterium arachidiradicis sp. nov. (type strain 91A-612T = LMG 27814T = CCM 8490T = CIP 110647T).

A Gram-negative, aerobic, rod-shaped, non-motile bacterium, designated BZ42T, was isolated from the soil of an industrial site. Strain BZ42T was able to grow at 5–25 °C. The major fatty acids were iso-C15 : 0 (46.2 %), C16 : 1 ω7c and/or iso-C15 : 0 2-OH (23.2 %) and iso-C17 : 0 3-OH (9.1 %). The predominant menaquinone was MK-7. The genomic DNA G+C content was 36.5 mol% (HPLC). 16S rRNA gene sequence phylogenetic analysis revealed that strain BZ42T was a member of the genus Pedobacter, family Sphingobacteriaceae, and 16S rRNA gene sequence similarities between strain BZ42T and the type strains of species of the genus Pedobacter with validly published names were 90.4–93.2 %. On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain BZ42T was considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter bauzanensis sp. nov. is proposed. The type strain is BZ42T (=DSM 22554T =CGMCC 1.10187T =CIP 110134T).

An aerobic, motile, Gram-positive strain, DX3-12T, was isolated from coastal sediment of the Eastern China Sea in Fujian Province, China, and was identified by means of polyphasic taxonomy. On the basis of 16S rRNA gene sequence similarity, strain DX3-12T was closely related to members of the genera Planomicrobium and Planococcus. 16S rRNA gene sequence similarities between strain DX3-12T and Planomicrobium mcmeekinii, Planomicrobium koreense, Planomicrobium okeanokoites, Planococcus psychrophilus and Planococcus alkanoclasticus were 97·8, 97·8, 97·1, 97·5 and 96·4 %, respectively. Chemotaxonomic and physiological properties of strain DX3-12T supported its affiliation to the genus Planomicrobium. Strain DX3-12T and Planomicrobium mcmeekinii exhibited common phenotypic properties such as the ability to reduce nitrate, but they could be distinguished from each other by physiological and biochemical tests, e.g. acid production from glucose, growth temperature and NaCl concentration requirements. DNA–DNA hybridization further distinguished strain DX3-12T from Planomicrobium mcmeekinii at the species level. Therefore, it is proposed that strain DX3-12T (=AS 1.3454T=JCM 12466T) represents a novel species, Planomicrobium chinense sp. nov. Based on 16S rRNA gene sequence similarities, signature nucleotides, cell morphology and physiological and biochemical properties, Planococcus psychrophilus and Planococcus alkanoclasticus have been transferred to the genus Planomicrobium as Planomicrobium psychrophilum comb. nov. (type strain DSM 14507T=MTCC 3812T) and Planomicrobium alkanoclasticum comb. nov. (type strain NCIMB 13489T=CIP 107718T), respectively.

Two bacterial isolates from ginseng fields in Korea, strains GR17-7T and GP18-1T, were characterized using a polyphasic approach. Phylogenetic analysis of their 16S rRNA gene sequences revealed a clear affiliation with the Gammaproteobacteria, and showed that the closest phylogenetic relationships were with members of the genus Rhodanobacter. The 16S rRNA gene sequence similarity between strains GR17-7T and GP18-1T was 97.2 %. Both strains showed 16S rRNA gene sequence similarities of 95.2–96.9 % to type strains of recognized Rhodanobacter species. The G+C contents of the DNA of strains GR17-7T and GP18-1T were 61.0 and 62.5 mol%, respectively. According to the DNA–DNA hydridization tests, the hybridization value between strains GR17-7T and GP18-1T was 34 %. Strains GR17-7T and GP18-1T showed less than 32 % DNA–DNA relatedness with Rhodanobacter fulvus KCTC 12098T and Rhodanobacter spathiphylli LMG 23181T. Strains GR17-7T and GP18-1T were aerobic, Gram-negative, rod-shaped, and catalase- and oxidase-positive. Major fatty acids of both strains were iso-C17 : 1 ω9c and iso-C16 : 0. Based on the data presented, two novel Rhodanobacter species are proposed, with the names Rhodanobacter ginsengisoli sp. nov. (type strain GR17-7T=KACC 11762T=DSM 18993T) and Rhodanobacter terrae sp. nov. (type strain GP18-1T=KACC 11761T=DSM 19241T).
