Gene Sequence Analysis

Three bacterial strains, designated MT1T, RW10T and IpA-2T, had been isolated previously for their ability to degrade chlorosalicylates or isopimaric acid. 16S rRNA gene sequence analysis demonstrated that these bacteria are related to species of the genus Pseudomonas. Analysis of the results of DNA–DNA hybridization with several close phylogenetic neighbours revealed a low level of hybridization (less than 57 %). On the basis of phenotypic characteristics, phylogenetic analysis, DNA–DNA relatedness data and chemotaxonomic analysis, it is concluded that these isolates represent separate novel species, for which the names Pseudomonas reinekei sp. nov. (type strain MT1T =DSM 18361T=CCUG 53116T), Pseudomonas moorei sp. nov. (type strain RW10T =DSM 12647T=CCUG 53114T) and Pseudomonas mohnii sp. nov. (type strain IpA-2T =DSM 18327T=CCUG 53115T) are proposed.

Emended Description

Two novel actinobacteria isolates, designated YIM 70009T and YIM 70081T, were characterized in order to determine their taxonomic position. Cells of strains YIM 70009T and YIM 70081T were cocci, although only the latter were motile. The G+C contents of their DNAs were 64·0 and 64·5 mol%, respectively. On the basis of chemotaxonomic characteristics and 16S rRNA gene sequence analysis, the two isolates were classified in the genus Nesterenkonia. DNA–DNA hybridization and comparison of phenotypic characteristics revealed that strains YIM 70009T and YIM 70081T differed from each other and from known species. Therefore, it is proposed that they represent two separate novel species of the genus Nesterenkonia: Nesterenkonia sandarakina sp. nov. (type strain, YIM 70009T=CCTCC AA 203007T=DSM 15664T=KCTC 19011T) and Nesterenkonia lutea sp. nov. (type strain, YIM 70081T=CCTCC AA 203010T=DSM 15666T=KCTC 19013T).

Three novel bacterial strains were isolated from a soil sample collected in Japan by culture on a GPM agar plate supplemented with superoxide dismutase and catalase. The strains were Gram-positive, catalase-positive, non-motile bacteria with l-ornithine as a diagnostic diamino acid of the peptidoglycan. The acyl type of the peptidoglycan was N-glycolyl. The major menaquinones were MK-12, 13 and 14. Mycolic acids were not detected. G+C contents of the DNA were in the range 69–71 mol%. Comparative 16S rRNA gene sequence analysis revealed that the isolates belonged to the genus Microbacterium and were closely related to Microbacterium terregens, Microbacterium aurum, Microbacterium koreense, Microbacterium schleiferi and Microbacterium lacticum. However, M. aurum, M. koreense and M. lacticum clearly differed from the isolated strains based on the presence of l-lysine as the cell-wall diamino acid and various other chemotaxonomic characteristics. Levels of DNA–DNA relatedness showed that the isolated strains represented three separate genomic species. Based on both phenotypic and genotypic data, the following novel species of the genus Microbacterium are proposed: Microbacterium deminutum sp. nov. (type strain KV-483T=NRRL B-24453T=NBRC 101278T), Microbacterium pumilum sp. nov. (type strain KV-488T=NRRL B-24452T=NBRC 101279T) and Microbacterium aoyamense sp. nov. (type strain KV-492T=NRRL B-24451T=NBRC 101280T).

Sequence Similarities

Two yellow-pigmented, Gram-negative, rod-shaped bacterial strains, GH1-10T and GH29-5T, were isolated from greenhouse soils in Korea. 16S rRNA gene sequence analysis indicated that these strains were related to members of the genus Flavobacterium. Strain GH1-10T was most closely related to Flavobacterium psychrolimnae and Flavobacterium denitrificans, with sequence similarities of 95.9 and 95.2 %, respectively. Strain GH29-5T was most closely related to ‘Flavobacterium saliodium’, F. denitrificans and Flavobacterium frigoris, with sequence similarities of 94.3, 92.5 and 92.5 %, respectively. The major cellular fatty acids of GH1-10T were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and iso-C17 : 0 3-OH, and those of GH29-5T were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. Both strains contained menaquinone with six isoprene units (MK-6) as the sole quinone. The DNA G+C contents of GH1-10T and GH29-5T were 35 and 39 mol%, respectively. Based on the phylogenetic and phenotypic data presented, it is concluded that the two bacteria represent two separate novel species of the genus Flavobacterium. The names proposed to accommodate these organisms are Flavobacterium daejeonense sp. nov., with type strain GH1-10T (=KACC 11422T=DSM 17708T), and Flavobacterium suncheonense sp. nov., with type strain GH29-5T (=KACC 11423T=DSM 17707T).

Gene Sequence Analysis

The taxonomic position of strain JCM 2765T isolated from fermented cane molasses in Thailand was reinvestigated. Strain JCM 2765T was originally identified as representing Lactobacillus buchneri on the basis of biochemical and physiological characteristics. In the present study, 16S rRNA gene sequence analysis of strain JCM 2765T demonstrated a low level of similarity with the type strain of L. buchneri (92.5 %) and high levels with those of Lactobacillus collinoides (97.6 %) and Lactobacillus paracollinoides (98.0 %). Ribotyping was applied to investigate the relationships between strain JCM 2765T, L. collinoides and L. paracollinoides. The dendrogram based on ribotyping patterns showed one cluster for six strains of L. paracollinoides, and that strain JCM 2765T and L. collinoides JCM 1123T were each independent. Based on additional phenotypic findings and DNA–DNA hybridization results, strain JCM 2765T is considered to represent a novel species of the genus Lactobacillus, for which the name Lactobacillus similis sp. nov. is proposed. The type strain is JCM 2765T (=LMG 23904T).

The 16S Rrna Gene

A novel Gram-staining-positive, rod-shaped bacterium, designated DCY100T, was isolated from rhizome of mountain ginseng root in Hwacheon mountain, Gangwon province, Republic of Korea. The 16S rRNA gene sequence analysis showed that strain DCY100T belonged to the genus Microbacterium and was most closely related to Microbacterium ginsengisoli KCTC 19189T (97.9 %), Microbacterium lacus JCM 15575T (97.2 %) and Microbacterium invictum DSM 19600T (97.1 %). The major menaquinones were MK-11 and MK-12. The major polar lipids were found to be diphosphatidylglycerol, phosphatidylglycerol and one unidentified glycolipid. The major fatty acids (>10.0 %) were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The cell-wall peptidoglycan contained the amino acids ornithine, alanine, glutamic acid and glycine; whole-cell sugars consisted of glucose, galactose, rhamnose and ribose. The DNA G+C content was 63.6 ± 0.7 mol%. The DNA–DNA hybridization relatedness values between strain DCY100T and Microbacterium ginsengisoli KCTC 19189T, Microbacterium lacus JCM 15575T and Microbacterium invictum DSM 19600T were 36.2 ± 0.4, 22.0 ± 3.0 and 15.3 ± 1.8 %, respectively. On the basis of phenotypic, chemotaxonomic and genotypic analyses, the isolate is classified as a representative of a novel species in the genus Microbacterium, for which the name Microbacterium rhizomatis DCY100T is proposed. The type strain is DCY100T ( = KCTC 39529T = JCM 30598T).

A Gram-negative, non-spore-forming, rod-shaped bacterium, designated strain DCY01T, was isolated from soil from a ginseng field in South Korea and was characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain DCY01T belonged to the Gammaproteobacteria and was most closely related to Stenotrophomonas koreensis KCTC 12211T (98.4 % similarity), Stenotrophomonas humi R-32729T (97.2 %), Stenotrophomonas terrae R-32768 (97.1 %), Stenotrophomonas maltophilia DSM 50170T (96.9 %) and Stenotrophomonas nitritireducens DSM 12575T (96.8 %). Chemotaxonomic analyses revealed that strain DCY01T possessed a quinone system with Q-8 as the predominant compound, and iso-C15 : 0 (28.2 %), C16 : 0 10-methyl (13.2 %), iso-C15 : 1 F (10.8 %) and C15 : 0 (7.5 %) as major fatty acids, corroborating assignment of strain DCY01T to the genus Stenotrophomonas. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that strain DCY01T represents a species distinct from recognized Stenotrophomonas species. Based on these data, DCY01T (=KCTC 12539T=NBRC 101154T) should be classified as the type strain of a novel species of the genus Stenotrophomonas, for which the name Stenotrophomonas ginsengisoli sp. nov. is proposed.

A Gram-reaction-negative, rod-shaped marine bacterium, designated MEBiC08158T, was isolated from sediments collected from Taean County, Korea, near the Hebei Spirit tanker oil spill accident. 16S rRNA gene sequence analysis revealed that strain MEBiC08158T was closely related to Alcanivorax marinus R8-12T (99.5 % similarity) but was distinguishable from other members of the genus Alcanivorax (93.7–97.1 %). The DNA–DNA hybridization value between strain MEBiC08158T and A. marinus R8-12T was 58.4 %. Growth of strain MEBiC08158T was observed at 15–43 °C (optimum 37–40 °C), at pH 6.0–9.5 (optimum pH 7.0–8.0) and with 0.5–16 % NaCl (optimum 1.5–3.0 %). The dominant fatty acids were C16 : 0, C19 : 0 cyclo ω8c, C12 : 0, C18 : 1ω7c, C12 : 0 3-OH and summed feature 3 (comprising C15 : 0 2-OH and/or C16 : 1ω7c). Several phenotypic characteristics differentiate strain MEBiC08158T from phylogenetically close members of the genus Alcanivorax. Therefore, strain MEBiC08158T should be classified as representing a novel species of the genus Alcanivorax, for which the name Alcanivorax gelatiniphagus sp. nov. is proposed. The type strain is MEBiC08158T ( = KCCM 42990T = JCM 18425T).

One bacterial strain, designated 5GH38-5T, which was characterized as aerobic, Gram-staining-negative, non-flagellated rods, was isolated from a soil sample from a greenhouse in Sangju region, Republic of Korea. It grew at temperatures of 15–45 °C, pH 5.0–9.0 and NaCl concentrations (w/v) of 0–3.0 %. 16S rRNA gene sequence analysis showed the strain was closely related to Pseudoxanthomonas kaohsiungensis J36T (97.3 %), Pseudoxanthomonas suwonensis 4M1T (96.8 %), Pseudoxanthomonas daejeonensis TR6-08T (96.7 %) and Pseudoxanthomonas kalamensis JA40T (96.7 %). Its major fatty acids were iso-C16 : 0, anteiso-C15 : 0 and iso-C15 : 0. The predominant ubiquinone was Q-8. The major polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content was 71.1 mol%. The DNA–DNA hybridization value between strain 5GH38-5T and P. kaohsiungensis J36T was less than 70 %. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain 5GH38-5T could be clearly distinguished from closely related members of the genus Pseudoxanthomonas. Therefore, the results of this study indicated the existence of a novel species of the genus Pseudoxanthomonas, for which we propose the name Pseudoxanthomonas sangjuensis sp. nov., with strain 5GH38-5T ( = KACC 16961T = DSM 28345T = JCM 19948T) as the type strain.

The taxonomic positions of ‘Renobacter vacuolatum’ DSM 1277 and ‘Ancylobacter polymorphus’ DSM 2457 were investigated in this study. 16S rRNA gene sequence analysis indicated that both strains belonged to the genus Ancylobacter. DNA–DNA hybridization showed that they differed from Ancylobacter aquaticus DSM 101T and Ancylobacter rudongensis AS 1.1761T. According to molecular and phenotypic characteristics, strain DSM 1277T (=AS 1.2807T) is proposed as the type strain of Ancylobacter vacuolatus sp. nov. At the same time, valid publication of the name Ancylobacter polymorphus sp. nov. is proposed, with the type strain DSM 2457T (=AS 1.2800T=NCIMB 10516T).
