Phenotypic Tests

Eleven strains of anaerobic Gram-negative bacilli isolated from the human oral cavity were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise two homogeneous groups, designated E2 and E4. 16S rRNA gene sequence analysis revealed that members of both groups belonged to the genus Prevotella but were distinct from any species with validly published names. This distinction was confirmed by DNA–DNA hybridization and phenotypic tests. Two novel species are therefore proposed: Prevotella marshii sp. nov. (group E2) and Prevotella baroniae (group E4). Both species are saccharolytic; the end-products of fermentation for P. marshii are acetic, propionic and succinic acids, while P. baroniae produces acetic and succinic acids with minor amounts of isovaleric and isobutyric acids. The G+C content of the DNA of the type strain of Prevotella marshii is 51 mol% and that of Prevotella baroniae is 52 mol%. The type strain for P. marshii is E9.34T (=DSM 16973T=CCUG 50419T) and that for P. baroniae is E9.33T (=DSM 16972T=CCUG 50418T).

Two strains of anaerobic, Gram-stain-negative bacilli isolated from the human oral cavity (D033B-12-2T and D080A-01) were subjected to a comprehensive range of phenotypic and genotypic tests and were found to be distinct from any previously described species. 16S rRNA gene sequence analysis revealed that the strains were related most closely to the type strain of Prevotella marshii (93.5 % sequence identity). The novel strains were saccharolytic and produced acetic acid and succinic acid as end products of fermentation. The principal cellular long-chain fatty acids were C16 : 0, iso-C14 : 0, C14 : 0, anteiso-C15 : 0, iso-C16 : 0 and C16 : 0 3-OH. The G+C content of the DNA of strain D033B-12-2T was 44 mol%. Strains D033B-12-2T and D080A-01 are considered to represent a single novel species of the genus Prevotella, for which the name Prevotella saccharolytica sp. nov. is proposed. The type strain is D033B-12-2T (=DSM 22473T =CCUG 57944T).

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).

A Gram-staining-negative, halophilic, facultatively anaerobic, motile, rod-shaped and nitrogen-fixing bacterium, designated strain S37T, was isolated from an artificial oil-spill sediment sample from the coast of Taean, South Korea. Cells grew at 10–37 °C and pH 5.0–9.0, with optimal growth at 28 °C and pH 6.0–8.0. Growth was observed with 1–9 % (w/v) NaCl in marine broth, with optimal growth with 3–5 % NaCl, but no growth was observed in the absence of NaCl. According to the results of 16S rRNA gene sequence analysis, strain S37T represents a member of the genus Vibrio of the class Gammaproteobacteria and forms a clade with Vibrio plantisponsor MSSRF60T (97.38 %), Vibrio diazotrophicus ATCC 33466T (97.31 %), Vibrio aestuarianus ATCC 35048T (97.07 %) Vibrio areninigrae J74T (96.76 %) and Vibrio hispanicus LMG 13240T (96.76 %). The major fatty acids were C16 : 0, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c. The DNA G+C content was 41.9 %. The DNA–DNA hybridization analysis results showed a 30.2 % association value with the closely related type strain V. plantisponsor DSM 21026T. On the basis of phenotypic and chemotaxonomic characteristics, strain S37T represents a novel species of the genus Vibrio, for which the name Vibrio oceanisediminis sp. nov., is proposed with the type strain S37T ( = KEMB 2255-005T = JCM 30409T).

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.

Ten strains of Gram-stain-negative, non-spore-forming, non-motile coccobacilli were isolated from the plaster wall surface of 1300-year-old mural paintings inside the stone chamber of the Takamatsuzuka tumulus in Asuka village (Asuka-mura), Nara Prefecture, Japan. Based on 16S rRNA gene sequence analysis of the isolates, they belonged to the proteobacterial genus Bordetella (class Betaproteobacteria) and could be separated into three groups representing novel lineages within the genus Bordetella. Three isolates were selected, one from each group, and identified carefully using a polyphasic approach. The isolates were characterized by the presence of Q-8 as their major ubiquinone system and C16 : 0 (30.0–41.8 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 10.1–27.0 %) and C17 : 0 cyclo (10.8–23.8 %) as the predominant fatty acids. The major hydroxy fatty acids were C12 : 0 2-OH and C14 : 0 2-OH. The DNA G+C content was 59.6–60.0 mol%. DNA–DNA hybridization tests confirmed that the isolates represented three separate novel species, for which the names Bordetella muralis sp. nov. (type strain T6220-3-2bT = JCM 30931T = NCIMB 15006T), Bordetella tumulicola sp. nov. (type strain T6517-1-4bT = JCM 30935T = NCIMB 15007T) and Bordetella tumbae sp. nov. (type strain T6713-1-3bT = JCM 30934T = NCIMB 15008T) are proposed. These results support previous evidence that members of the genus Bordetella exist in the environment and may be ubiquitous in soil and/or water.

Distinct Genus

Comparative 16S rRNA gene sequence analysis indicates that two distinct sublineages exist within the genus Alcaligenes: the Alcaligenes faecalis lineage, comprising Alcaligenes aquatilis and A. faecalis (with the three subspecies A. faecalis subsp. faecalis, A. faecalis subsp. parafaecalis and A. faecalis subsp. phenolicus), and the Alcaligenes defragrans lineage, comprising A. defragrans. This phylogenetic discrimination is supported by phenotypic and chemotaxonomic differences. It is proposed that the A. defragrans lineage constitutes a distinct genus, for which the name Castellaniella gen. nov. is proposed. The type strain for Castellaniella defragrans gen. nov., comb. nov. is 54PinT (=CCUG 39790T=CIP 105602T=DSM 12141T). Finally, on the basis of data from the literature and new DNA–DNA hybridization and phenotypic data, the novel species Castellaniella denitrificans sp. nov. (type strain NKNTAUT=DSM 11046T=CCUG 39541T) is proposed for two strains previously identified as strains of A. defragrans.

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 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.

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.
