Abstract
Biodegradation is a sustainable green strategy that gives the opportunity for remediation of water contaminated with petroleum products. In this study, 12 bacterial isolates were recovered from River Nile, Egypt and screened for their potential to degrade a mixture of paraffinic petroleum crude oil. The most promising isolate was identified according to 16S rRNA sequencing as Janibacter terrae strain S1N1 (GenBank accession No. KX570955.1). In order to boost the biodegradation efficiency, the bacterial suspension was photostimulated by exposure to different irradiation doses using a low-power helium-neon (He-Ne) laser (λ = 632.8 nm). Maximum biodegradation was achieved after 4 min of exposure (134.07 J cm-2) at optimized pH value (6) and temperature (35 °C). The gas chromatography-mass spectrometry (GC-MS) analysis revealed the biodegradation of 96.5% of the substrate after only 48 h of incubation. The n-C17/Pr and n-C18/Ph ratios indicated a preferential biodegradation of iso-paraffines over normal ones. Meanwhile, pristane/phytane (Pr/Ph) ratios were indicative of selective biodegradation for pristane. The carbon preference index (CPI) was nearly around unity indicating the ability of Janibacter terrae to attack the odd and even n-alkanes simultaneously. These results support the superiority of irradiated bacteria in optimizing the biodegradation efficiency and shortening the time of treatment, thus proposing an eco-friendly technique in water bioremediation programs.

Abstract
A novel endophytic actinobacterium, designated as strain YIM B02568T, was isolated from the root of Paris polyphylla Smith var. Yunnanensis obtained from Yunnan Province, southwest China. Strain YIM B02568T was characterized using a polyphasic approach. Phylogenetic analysis indicated that this isolate belonged to the genus Janibacter. The 16S rRNA gene sequence similarity values of strain YIM B02568T to the type strains of members of this genus ranged from 95.8 to 98.6%. However, overall genome relatedness indices were significantly lower than the widely accepted species-defined threshold. The cell wall of strain YIM B02568T contained meso-diaminopimelic acid. The major menaquinone was MK-8(H4). The main polar lipids were phosphatidylglycerol, diphosphatidylglycerol, and phosphatidylinositol. The major cellular fatty acids were comprised of iso-C16:0 and C18:1 ω9c. The DNA G + C content was 71.6 mol%. Based on the data from the polyphasic studies, we propose that strain YIM B02568T represents a novel species within the genus Janibacter, Janibacter endophyticus sp. nov. The type strain is YIM B02568T (= JCM 34639T = CGMCC 1.18658T).

Abstract
Introduction Janibacter caused bacteriemia is one of the rare infections. Methods In the present study, we report the first isolation of Janibacter, a rare bacterial infection, from a bacteremia patient in China. Its 16S rDNA was amplified and designated as Janibacter YFY001, which belongs to J. indicus. In addition, its genome was sequenced through combined second- and third-generation genome sequencing methods. Results Based on its genome, we identified many virulence factors, such as catalase, gelatinase, FbpABC systems, and resistant genes, among others. Interestingly, three genomic islands were found in YFY001 by comparing its genome to environmental Janibacter strains. Discussion Our study not only provides the necessary genomic information for in-depth study of Janibacter, but also provides a novel methodology for studying future cases of rare bacterial infection.

Abstract
The authors report isolation and identification of two strains of bacteria belonging to the genus Janibacter from a human patient with aortic stenosis from a rural area of the country of Georgia. The microorganisms were isolated from aortic heart valve. Two isolates with slightly distinct colony morphologies were harvested after sub-culturing from an original agar plate. Preliminary identification of the isolates is based on amplification and sequencing of a fragment of 16SrRNA. Whole genome sequencing was performed using the Illumina MiSeq instrument. Both isolates were identified as undistinguished strains of the genus Janibacter. Characterization of whole genome sequences of each culture has revealed a 15% difference in gene profile between the cultures and confirmed that both strains belong to the genus Janibacter with the closest match to J. terrae. Genomic comparison of cultures of Janibacter obtained from human cases and from environmental sources presents a promising direction for evaluating a role of these bacteria as human pathogens.

Abstract
Strain Marseille-P4121T was isolated from a vaginal sample of a 45-year-old French woman with bacterial vaginosis. It is a Gram-positive, asporogenous, non-motile and aerobic bacterium. Strain Marseille-P4121T exhibits 98.2% 16S rRNA sequence similarity with Janibacter alkaliphilus strain SCSIO 10480T, a phylogenetically closely related species with standing in nomenclature. Its major fatty acids were identified as C18:1ω9 (34.4%), C16:0 (30.1%), and C18:0 (19%). The draft genome size of strain Marseille-P4121T is 2,452,608 bp long with a 72.5% G+C content and contains 2351 protein-coding genes and 49 RNA genes including 3 rRNA genes. We propose that strain Marseille-P4121T (= CECT 9671T = CSUR P4121T) is the type strain of the new species Janibacter massiliensis sp. nov.

Abstract
Many pentachlorophenol- (PCP-) contaminated environments are characterized by low or elevated temperatures, acidic or alkaline pH, and high salt concentrations. PCP-degrading microorganisms, adapted to grow and prosper in these environments, play an important role in the biological treatment of polluted extreme habitats. A PCP-degrading bacterium was isolated and characterized from arid and saline soil in southern Tunisia and was enriched in mineral salts medium supplemented with PCP as source of carbon and energy. Based on 16S rRNA coding gene sequence analysis, the strain FAS23 was identified as Janibacter sp. As revealed by high performance liquid chromatography (HPLC) analysis, FAS23 strain was found to be efficient for PCP removal in the presence of 1% of glucose. The conditions of growth and PCP removal by FAS23 strain were found to be optimal in neutral pH and at a temperature of 30 °C. Moreover, this strain was found to be halotolerant at a range of 1-10% of NaCl and able to degrade PCP at a concentration up to 300 mg/L, while the addition of nonionic surfactant (Tween 80) enhanced the PCP removal capacity.

Abstract
A Gram-staining-positive, aerobic and non-motile strain, 0704P10-1T, was isolated from hydrothermal sediment of the Indian Ocean. Phylogenetic, phenotypic and chemotaxonomic data for the organism supported that it belonged to the genus
Janibacter
. Strain 0704P10-1T showed 97.2–98.7 % 16S rRNA gene sequence similarities to the type strains of recognized members of the genus
Janibacter
. It contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall. MK-8(H4) was the only menaquinone detected. The major fatty acids were iso-C16 : 0, C17 : 1ω8c and 10-methyl C17 : 0. Meanwhile, the results of DNA–DNA hybridization studies and other physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain 0704P10-1T from closely related species. Thus, strain 0704P10-1T represents a novel species of the genus
Janibacter
, for which the name Janibacter indicus sp. nov. is proposed. The type strain is 0704P10-1T ( = LMG 27493T = CGMCC 1.12511T).

Abstract
A Gram-positive, aerobic, non-spore-forming actinobacterial strain, designated strain TL1T, was isolated from pig manure in Wuhan, China. The cell wall peptidoglycan contained meso-diaminopimelic acid. The major polar lipids were phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The predominant menaquinone was MK-8(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C15 : 0 and C17 : 1ω8c. The genomic DNA G+C content was 70.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TL1T was most closely related to the type strains of Knoellia sinensis (98.5 %), Knoellia subterranea (98.2 %) and Knoellia aerolata (96.9 %). DNA–DNA relatedness values of strain TL1T with the type strains of K. sinensis and K. subterranea were 27.3 and 34.0 %, respectively. Comparison of phenotypic, chemotaxonomic and phylogenetic characteristics among strain TL1T and related organisms revealed that the isolate represents a novel species of the genus Knoellia, for which the name Knoellia flava sp. nov. is proposed; the type strain is TL1T ( = CGMCC 1.10749T = KCTC 19810T).

Abstract
A Gram-positive-staining, aerobic, catalase- and oxidase-positive, irregular short rod-shaped actinobacterium, designated strain YIM C003T, was isolated from a salt mine in Yunnan, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM C003T was most closely related to strains of the genera Knoellia (94.2-96.0% similarity), Oryzihumus (95.6%), Terrabacter (94.9-95.4%), Janibacter (94.9-95.4%), Kribbia (95.0%), Lapillicoccus (95.0%) and Phycicoccus (94.2-95.0%) of the family Intrasporangiaceae and that it formed an independent monophyletic lineage with three strains of Oryzihumus leptocrescens. The DNA G+C content of strain YIM C003T was 72.0 mol%. The diagnostic cell-wall diamino acid was meso-diaminopimelic acid. The predominant menaquinone was MK-8(H4). Mycolic acids were not detected. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and two unknown phospholipids. The major cellular fatty acids were C18:1omega9c and C16:0. These chemotaxonomic properties, together with data from phylogenetic analysis, enabled the novel isolate to be differentiated from all other members of the family. A novel species in a new genus, Fodinibacter luteus gen. nov., sp. nov., is proposed, with strain YIM C003T (=DSM 21208T=CCTCC AA 208036T) as the type strain of Fodinibacter luteus.

Abstract
Five novel endospore-forming, nitrogen-fixing bacterial strains were isolated from the rhizosphere soils of plants of the species Sabina squamata, Weigela florida and Zanthoxylum simulans. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the five strains formed a distinct cluster within the genus Paenibacillus. These novel strains showed the highest levels (96.2-98.2 %) of 16S rRNA gene sequence similarity with Paenibacillus azotofixans. However, the DNA-DNA relatedness between these novel strains and P. azotofixans was 12.9-29.5 %. The DNA G+C contents of the five strains were found to be 51.9-52.9 mol%. Phenotypic analyses showed that a significant feature of the novel strains (differentiating them from P. azotofixans and other Paenibacillus species) is that all of them were unable to produce acid and gas from various carbohydrates such as glucose, sucrose, lactose and fructose. Anteiso-branched C(15 : 0) was the major fatty acid present in the novel type strain. On the basis of these data, the five novel strains represent a novel species of the genus Paenibacillus, for which the name Paenibacillus sabinae sp. nov. is proposed. The type strain is T27(T) (=CCBAU 10202(T)=DSM 17841(T)).

Abstract
A novel Janibacter species is described on the basis of phenotypic, chemotaxonomic and genotypic data. Two bacterial strains were isolated in Palau, which were both Gram-positive, catalase-positive bacteria with meso-diaminopimelic acid as the diagnostic diamino acid of the peptidoglycan. The major menaquinone was MK-8(H(4)). Mycolic acids were not detected. The G+C content of the DNA was 70-71 mol%. Comparative 16S rDNA studies of the two isolated strains revealed that they both belonged to the genus Janibacter. DNA-DNA relatedness data revealed that 04PA2-Co5-61(T) and 02PA-Ca-009 belong to the same species, a new species of the genus Janibacter. From these results, Janibacter corallicola sp. nov. is proposed, with the type strain 04PA2-Co5-61(T) (=MBIC 08265(T), DSM 18906(T)).

Abstract
Despite differences in their morphologies, comparative analyses of 16S rRNA gene sequences revealed high levels of similarity (>94 %) between strains of the filamentous bacterium ‘Candidatus Nostocoida limicola’ and the cocci Tetrasphaera australiensis and Tetrasphaera japonica and the rod Tetrasphaera elongata, all isolated from activated sludge. These sequence data and their chemotaxonomic characters, including cell wall, menaquinone and lipid compositions and fingerprints of their 16S–23S rRNA intergenic regions, support the proposition that these isolates should be combined into a single genus containing six species, in the family Intrasporangiaceae in the Actinobacteria. This suggestion receives additional support from DNA–DNA hybridization data and when partial sequences of the rpoC1 gene are compared between these strains. Even though few phenotypic characterization data were obtained for these slowly growing isolates, it is proposed, on the basis of the extensive chemotaxonomic and molecular evidence presented here, that ‘Candidatus N. limicola’ strains Ben 17, Ben 18, Ben 67, Ben 68 and Ben 74 all be placed into the species Tetrasphaera jenkinsii sp. nov. (type strain Ben 74T=DSM 17519T=NCIMB 14128T), ‘Candidatus N. limicola’ strain Ben 70 into Tetrasphaera vanveenii sp. nov. (type strain Ben 70T=DSM 17518T=NCIMB 14127T) and ‘Candidatus N. limicola’ strains Ver 1 and Ver 2 into Tetrasphaera veronensis sp. nov. (type strain Ver 1T=DSM 17520T=NCIMB 14129T).

Abstract
Two Gram-positive, catalase-positive, irregular short rod- or coccoid-shaped bacterial strains, N113T and R33, were isolated from an enrichment culture with diesel oil-degradation activity and their taxonomic positions were investigated using a polyphasic approach. Phenotypic, phylogenetic and genetic similarities indicated that strains N113T and R33 were representatives of the same species. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains N113T and R33 form a lineage independent from those of members of the family Intrasporangiaceae. The novel isolates had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-8(H4) as the predominant menaquinone and 10-methyl-C18 : 0, iso-C16 : 0, C18 : 1
ω9c, C16 : 0 and C18 : 0 as the major cellular fatty acids. The DNA G+C contents were 69.6–69.9 mol%. These chemotaxonomic properties, together with phylogenetic distinctiveness, distinguish the two novel strains from recognized members of the family Intrasporangiaceae. On the basis of phenotypic, phylogenetic and genetic data, strains N113T (=KCTC 19143T=JCM 13585T) and R33 are classified as representatives of a novel genus and species, Kribbia dieselivorans gen. nov., sp. nov., within the family Intrasporangiaceae.

Abstract
A Gram-positive, aerobic, non-motile strain, H2.16BT, isolated from the midgut of the mosquito Anopheles arabiensis was investigated using a polyphasic approach. On the basis of 16S rRNA gene sequence similarity studies, strain H2.16BT was shown to belong to the genus Janibacter, being most closely related to Janibacter melonis (98.3%), Janibacter terrae (98.5%) and Janibacter limosus (98.5%). Chemotaxonomic data (meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall and major fatty acids of iso-C16:0, C17:1omega8c and C17:0)) supported the allocation of the strain to the genus Janibacter. The results of DNA-DNA hybridization and physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain H2.16BT from closely related species. Thus, H2.16BT represents a novel species of the genus Janibacter, for which the name Janibacter anophelis sp. nov. is proposed. The type strain is H2.16BT (=CCUG 49715T=CIP 108728T).

Abstract
Two Gram-positive bacterial strains, CM2104(T) and CM2110, isolated from the inner part of abnormally spoiled oriental melon (Cucumis melo) in Korea, were subjected to a polyphasic taxonomic study. The cell-wall peptidoglycan of strains CM2104(T) and CM2110 contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinone was MK-8(H(4)). The major fatty acids detected in the two strains were iso-C(16 : 0), C(17 : 1)omega8c and C(18 : 1)omega9c or C(17 : 0). The DNA G+C content of the two strains was 73 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strains formed a coherent cluster with a clade comprising two Janibacter species, Janibacter limosus and Janibacter terrae. Strains CM2104(T) and CM2110 exhibited a 16S rRNA gene sequence similarity value of 99.7 % and a mean DNA-DNA relatedness level of 89 %. Strains CM2104(T) and CM2110 showed 16S rRNA gene sequence similarity levels of 97.8-98.4 % to the type strains of J. limosus and J. terrae. DNA-DNA relatedness between strains CM2104(T) and CM2110 and the type strains of these two Janibacter species was 7-11 %. On the basis of the phenotypic and phylogenetic data and genomic distinctiveness, strains CM2104(T) and CM2110 should be placed within the genus Janibacter as members of a novel species, for which the name Janibacter melonis sp. nov. is proposed. The type strain is CM2104(T) (=KCTC 9987(T)=DSM 16063(T)=JCM 12321(T)).

Abstract
This is the first study to demonstrate that diverse methylotrophic bacteria occur in the human foot microflora. Polymerase chain reaction (PCR) amplification of DNA from the soles and toe clefts of feet of five subjects indicated Methylobacterium strains to be present in all cases. Polymerase chain reaction amplification also showed the gene for the alpha-subunit of methanol dehydrogenase (mxaF) to be present in all samples. Two types of mxaF were recovered, one closest to that of Methylobacterium extorquens and the other most similar to that of Hyphomicrobium methylovorum. Numerous methylotrophic strains able to grow on methylamine were isolated with ease from the feet of nine volunteers. These were found by 16S rRNA analysis to be most closely related to Methylobacterium species, Brevibacterium casei, Pseudomonas strain NZ099 and P. migulae. Three strains from two subjects were of a novel species, Methylobacterium podarium sp. nov. This facultatively methylotrophic, obligately aerobic, pink-pigmented, non-motile rod grew with a wide range of multicarbon and one-carbon compounds including citrate, xylose, mono-, di-, and trimethylamine, dimethylsulphide, methanethiol, dimethylsulphoxide, dimethylsulphone and methanol.

Abstract
An unknown Gram-positive, catalase-positive, facultatively anaerobic, non-spore-forming, coccus-shaped bacterium originating from sediment was characterized using phenotypic, molecular chemical and molecular phylogenetic methods. Chemical studies revealed the presence of a cell-wall murein based on ll-diaminopimelic acid (type ll-Dpm-glycine1), a complex mixture of saturated, monounsaturated and iso- and anteiso-methyl-branched, non-hydroxylated, long-chain cellular fatty acids and tetrahydrogenated menaquinones with eight isoprene units [MK-8(H4)] as the major respiratory lipoquinone. This combination of characteristics somewhat resembled members of the suborder Micrococcineae, but did not correspond to any currently described species. Comparative 16S rRNA gene sequencing confirmed that the unidentified coccus-shaped organism is a member of the Actinobacteria and represents a hitherto-unknown subline related to, albeit different from, a number of taxa including Intrasporangium, Janibacter, Terrabacter, Terracoccus and Ornithinicoccus. Based on phenotypic and phylogenetic considerations, it is proposed that the unknown bacterium originating from lake sediment be classified as a new genus and species, Arsenicicoccus bolidensis gen. nov., sp. nov. (type strain CCUG 47306T=DSM 15745T).

Abstract
We have isolated and characterised a novel aerobic bacterial strain, designated MS3-02, belonging to the genus Janibacter sp. The capability of this new strain to degrade polychlorinated biphenyls (PCBs) in a commercial mixture (Aroclor 1242) in liquid medium and in soil (sterile and non sterile soil), under laboratory scale, has been evaluated. MS3-02 was isolated from the soil around of an incinerator, located in the east of Madrid (Spain). Gas-chromatographic analysis showed that MS3-02 was able to reduce most peaks observed in the chromatogram between 70% and 100% after seven days of incubation in a culture mineral medium containing yeast extract, but without the addition of biphenyl. The presence of biphenyl in the culture medium decreased the rate of PCB degradation by this bacterium. Comparing the performance of the MS3-02 in liquid culture medium and in soil, degradation was less efficient in sterile soil and still less efficient in non sterile soil. Under the best conditions (sterile soil and 20 weeks of incubation) MS3-02 was able to reduce, between 50% and 100%, nine of the main gas-chromatographic peaks in Aroclor 1242.
