Gene Sequence Analysis

A Gram-negative, rod-shaped bacterium (CC-JY-1T) was isolated on nutrient agar from a soil sample collected from an oil-contaminated site located in Chyai county, Taiwan. 16S rRNA gene sequence analysis demonstrated that this isolate is unique, showing 96.7 % sequence similarity to the type strain of Arenimonas donghaensis and similarities of 93.0–93.8 % to species of the genera Thermomonas, Lysobacter and Silanimonas. The presence of ubiquinone Q-8, a polar lipid profile consisting of the major compounds diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine and the fatty acid profile were in accordance with the phylogenetic affiliation of CC-JY-1T. DNA–DNA reassociation experiments between CC-JY-1T and A. donghaensis KACC 11381T resulted in a mean relatedness value of 32 %, indicating that strain CC-JY1T represents a novel species in the genus Arenimonas, for which we propose the name Arenimonas malthae sp. nov. The type strain is CC-JY-1T (=CCUG 53596T =CIP 109310T).

Two bacterial strains, designated GH34-4T and GH41-7T, were isolated from greenhouse soil cultivated with cucumber. The bacteria were strictly aerobic, Gram-negative, rod-shaped and oxidase- and catalase-positive. 16S rRNA gene sequence analysis indicated that these strains belong to the genus Lysobacter within the Gammaproteobacteria. Strain GH34-4T showed highest sequence similarity to Lysobacter yangpyeongensis GH19-3T (97.5 %) and Lysobacter koreensis Dae16T (96.4 %), and strain GH41-7T showed highest sequence similarity to Lysobacter antibioticus DSM 2044T (97.5 %), Lysobacter enzymogenes DSM 2043T (97.5 %) and Lysobacter gummosus ATCC 29489T (97.4 %). Levels of DNA–DNA relatedness indicated that strains GH34-4T and GH41-7T represented species clearly different from L. yangpyeongensis, L. antibioticus, L. enzymogenes and L. gummosus. The major cellular fatty acids of strains GH34-4T and GH41-7T were iso-C16 : 0, iso-C15 : 0 and iso-C17 : 1 ω9c, and the major isoprenoid quinone was Q-8. The DNA G+C contents of GH34-4T and GH41-7T were 62.5 and 66.6 mol%, respectively. On the basis of the polyphasic taxonomic data presented, it is evident that each of these strains represents a novel species of the genus Lysobacter, for which the names Lysobacter niabensis sp. nov. (type strain GH34-4T=KACC 11587T=DSM 18244T) and Lysobacter niastensis sp. nov. (type strain GH41-7T=KACC 11588T=DSM 18481T) are proposed.

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

It was found to rod-shaped and aerobic or facultatively anaerobic. It grew optimally at 30 °C and at pH 6.5–7.0. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 1517T forms a distinct phylogenetic lineage within the genus Bacillus, being related to Bacillus funiculus JCM 11201T (96.8 %). The strain showed less than 94.3 % sequence similarity with other Bacillus species. The G+C content of the genomic DNA was found to be 47.8 mol% and the predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0 (42.4 %), anteiso-C15 : 0 (17.4 %), iso-C14 : 0 (9.7 %) and C16 : 0 (6.0 %). On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1517T represents a novel species of the genus Bacillus, for which the name Bacillus panaciterrae sp. nov. is proposed. The type strain is Gsoil 1517T (=KCTC 13929T=CCUG 52470T=LMG 23408T).

A Gram-reaction-negative, non-spore-forming, rod-shaped, aerobic bacterial strain, designated MJ11T, was isolated from sludge of a leachate treatment plant in Daejeon, South Korea, and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ11T belonged to the family Brucellaceae, class Alphaproteobacteria, and was most closely related to Ochrobactrum ciceri Ca-34T (97.9 % sequence similarity) and Ochrobactrum pituitosum CCUG 50899T (96.4 %). Comparative sequence analyses of the additional phylogenetic marker genes dnaK, groEL and gyrB confirmed the affiliation of strain MJ11T to the genus Ochrobactrum. The G+C content of the genomic DNA of strain MJ11T was 59.3 mol%. The detection of a quinone system with ubiquinone Q-10 as the predominant respiratory lipoquinone, a fatty acid profile with C18 : 1ω7c (62.6 %) and C19 : 0 cyclo ω8c (14.2 %) as the major components, a polar lipid profile with phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol and unknown aminolipids AL1 and AL2 as major polar lipids and spermidine and putrescine as the predominant polyamines also supported the affiliation of strain MJ11T to the genus Ochrobactrum. The DNA–DNA relatedness between strain MJ11T and Ochrobactrum ciceri DSM 22292T was 29±7 %, clearly showing that the isolate constitutes a new genospecies. Strain MJ11T could be clearly differentiated from its closest neighbours on the basis of its phenotypic, genotypic and chemotaxonomic features. Therefore, strain MJ11T represents a novel species of the genus Ochrobactrum, for which the name Ochrobactrum daejeonense sp. nov. is proposed. The type strain is MJ11T ( = KCTC 22458T  = JCM 16234T).

Abstract Two aerobic, Gram-stain variable, catalase and oxidase-positive, spore-forming, motile rods of strain UniB2T and UniB3T, were isolated from digestive syrup containing fungal diastase (10 mg/ml), pepsin (2 mg/ml) and sugar base containing polyethene glycol. Based on 16S rRNA gene sequence analysis, strain UniB2T has the highest sequence similarity with Paenibacillus humicus NBRC 102415T (98.30 %) and strain UniB3T showed the highest sequence similarity with Niallia circulans DSM 11T (98.95 %). The DNA G+C content of UniB2T was 63.74 mol %. The dDDH and ANI values between the strain UniB2T and its phylogenetically close relative were <38.3 % and <89.55 %, respectively. The major fatty acids of the strain UniB2T were C16:00 (13.9 %), C15:0 anteiso (39.7 %), C17:0 anteiso (15.5 %). The DNA G+C content of UniB3T was 35.6 mol%. The dDDH and ANI values between the strain UniB3T and its close relatives were <29.1 % and 84.62%, respectively. The major fatty acids of strain UniB3T were C16:0 (13.54 %), C15:0 anteiso (40.09 %) and C17:0 anteiso (16.03 %). Major polar lipids for both strains were Diphosphotidylglycerol and Phosphatidylethanolamine. Additionally, both the strains showed unique carbon utilization and assimilation pattern that differentiated them from their phylogenetically related neighbours. These phenotypic, genotypic and chemotaxonomic characters indicated the strains UniB2T and UniB3T represent two novel species for which the names Paenibacillus albicerus sp. nov. (Type strain UniB2T =MCC 3997T =KCTC 43095T =JCM34513T) and Niallia alba sp. nov. (Type strain UniB3T = MCC 3998T =KCTC 43235T =JCM 34492T) are proposed.

A novel actinomycete, strain N3-7T, was isolated from a natural cave in Jeju, Republic of Korea, using a dilution method and was subjected to characterization using polyphasic taxonomy. A 16S rRNA gene sequence analysis revealed that the organism belonged to the phylogenetic cluster of the genus Actinocorallia and was most closely related to Actinocorallia glomerata and Actinocorallia longicatena (97.6 and 97.5 % similarity, respectively). The main chemotaxonomic properties of strain N3-7T, such as the principal amino acid of the peptidoglycan, the predominant menaquinone and the polar lipid profile, supported classification in the genus Actinocorallia. The organism was readily differentiated from Actinocorallia species with validly published names on the basis of a broad range of phenotypic properties. Thus the isolate represents a novel species of the genus Actinocorallia, for which the name Actinocorallia cavernae sp. nov. is proposed. The type strain is strain N3-7T (=JCM 13278T=NRRL B-24429T).
