A Gram-stain-negative, aerobic, yellow-pigmented and non-motile rod-shaped bacterium, designated as GrpM-11T, was isolated from coastal seawater collected from the East Sea, Republic of Korea. Strain GrpM-11T could grow at 10–40 °C (optimum, 35 °C), at pH 5.5–9.5 (optimum, pH 7.0) and in the presence of 0–8 % (w/v) NaCl (optimum, 3–4 %). Cells hydrolysed aesculin, gelatin and casein, but could not reduce nitrate to nitrite. The 16S rRNA gene sequence analysis showed that this strain formed a distinct phylogenic lineage with Parasphingopyxis algicola ATAX6-5T (96.2 % sequence identity) and Parasphingopyxis lamellibrachiae DSM 26725T (96.2 % identity) and belonged to the genus Parasphingopyxis . The predominant isoprenoid quinone was ubiquinone-10. The polar lipid profile of strain GrpM-11T consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid and three unknown glycolipids. Cellular fatty acid analysis indicated that summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c; 42.8 %), C16 : 0 (19.0 %), C18 : 1 ω7c 11-methyl (13.3 %) and C18 : 1 ω7c (8.0 %) were the major fatty acids. The DNA G+C content of strain GrpM-11T was 63.7 mol%. Through whole genome sequence comparisons, the digital DNA–DNA hybridization and average nucleotide identity values between strain GrpM-11T and two species of the genus Parasphingopyxis were revealed to be in the ranges of 19.0–22.0 % and 76.3–79.7 %, respectively. Based on the results of polyphasic analysis, strain GrpM-11T represents a novel species of the genus Parasphingopyxis , for which the name Parasphingopyxis marina sp. nov. is proposed. The type strain is GrpM-11T (KCCM 43343T=JCM 34665T).

A total of 34 Corynebacterium sp. strains were isolated from caseous lymph node abscesses of wild boar and roe deer in different regions of Germany. They showed slow growth on Columbia sheep blood agar and sparse growth on Hoyle’s tellurite agar. Cellular fatty acid analysis allocated them in the C. diphtheriae group of genus Corynebacterium . MALDI-TOF MS using specific database extensions and rpoB sequencing resulted in classification as C. ulcerans . Their quinone system is similar to C. ulcerans , with major menaquinone MK-8(H2). Their complex polar lipid profile includes major lipids phosphatidylinositol, phosphatidylinositol-mannoside, diphosphatidylglycerol, but also unidentified glycolipids, distinguishing them clearly from C. ulcerans . They ferment glucose, ribose and maltose (like C. ulcerans ), but do not utilise d-xylose, mannitol, lactose, sucrose and glycogen (like C. pseudotuberculosis ). They showed activity of catalase, urease and phospholipase D, but variable results for alkaline phosphatase and alpha-glucosidase. All were non-toxigenic, tox gene bearing and susceptible to clindamycin, penicillin and erythromycin. In 16SrRNA gene and RpoB protein phylogenies the strains formed distinct brancheswith C. ulcerans as nearest relative.Whole genome sequencing revealed the unique sequence type 578, a distinctbranch in pangenomic core genome MLST, average nucleotide identities <91%, enhancedgenome sizes (2.55 Mbp) and G/C content (54.4 mol%) compared to related species.These results suggest that the strains represent a novel species, for which wepropose the name Corynebactriumsilvaticum sp. nov., based on their first isolation from forest-dwellinggame animals. The type strain isKL0182T (= CVUAS 4292T = DSM 109166T = LMG 31313T= CIP 111 672T).

A polyphasic taxonomic study was performed on an unidentified Arcanobacterium -like Gram-stain-positive bacterium designated strain C605018/01/1T isolated from a milk sample collected from the udder of a cow at post mortem. Comparative 16S rRNA gene sequencing showed that the bacterium belonged to the genus Arcanobacterium and was most closely related to the type strain of Arcanobacterium pluranimalium (99.76 %); sequence similarities to all other Arcanobacterium species were below 97 %. The wet-lab DNA–DNA hybridization values among strain C605018/01/1T and A. pluranimalium DSM 13483ᵀ were low, 16.9 % (reciprocal, 49.8 %). Pertaining to the whole genome sequence with a total length of 2.02 Mb and 1654 protein counts, the novel strain C605018/01/01T displayed a G+C content of 51.6 % mol%. The presence of the major menaquinone MK-9(H4) supported the affiliation of this strain to the genus Arcanobacterium . The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylcholine, phosphatidylinositol, phosphatidylinositol-mannoside and unidentified glycolipid and aminophospholipids. Based on these results it is proposed that strain C605018/01/1T should be classified as representing a novel species, Arcanbacterium bovis sp. nov. The type strain C605018/01/1T (CCUG 45425T=DSM 107286T=BCCM/LMG 30783T)

A novel Gram-staining-negative, catalase- and oxidase-positive, facultatively anaerobic and rod-shaped motile bacterial strain, designated as ZWAL4003T, was isolated from mangrove sediments of the Zini Mangrove Forest, Zhangzhou City, PR China. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that ZWAL4003T was grouped into a separated branch with Vibrio plantisponsor MSSRF60T (97.38% nucleotide sequence identity) and Vibrio diazotrophicus NBRC 103148T (97.27%). The major cellular fatty acids were C14 : 0 (12.6%), C16 : 0 (17.6%), and summed feature 3 (C16 : 1ω6c /C16 : 1 ω7c, 45.6%). Its genome had a length of 4650556 bp with 42.8% DNA G+C content, and contained genes involved in the biosynthesis of bacteriocin, β-lactone, resorcinol, N-acyl amino acid, and arylpolyene. The in silico DNA–DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between ZWAL4003T and V. plantisponsor LMG 24470T were clearly below the thresholds used for the delineation of a novel species. The morphological and chemotaxonomic characteristics and the genotypic data of ZWAL4003T indicated that it represented a novel species of the genus Vibrio . Its proposed name is Vibrio ziniensis sp. nov., and the type strain is ZWAL4003T (=KCTC 72971T=MCCC 1A17474T).

Degrading Bacterium

A non-sporulating, non-motile, catalase- and oxidase-positive, Gram-negative, rod-shaped bacterial strain, designated BA-3T, was isolated from activated sludge of a wastewater treatment facility. The strain was able to degrade about 95 % of 100 mg 3-phenoxybenzoic acid l−1 within 2 days of incubation. Growth occurred in the presence of 0–2 % (w/v) NaCl [optimum, 0.5 % (w/v) NaCl], at pH 5.5–9.0 (optimum, pH 7.0) and at 10–37 °C (optimum, 28 °C). Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain BA-3T was a member of the genus Sphingobium ; it showed highest gene sequence similarity to Sphingobium qiguonii X23T (98.2 %), and similarities of <97.0 % with strains of other Sphingobium species. The polar lipid pattern, the presence of spermidine and ubiquinone Q-10, the predominance of summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) in the cellular fatty acid profile and the DNA G+C content also supported affiliation of the isolate to the genus Sphingobium . Strain BA-3T showed low DNA–DNA relatedness values (21.3±0.8 %) with Sphingobium qiguonii X23T. Based on phenotypic, genotypic and phylogenetic data, strain BA-3T represents a novel species of the genus Sphingobium , for which the name Sphingobium jiangsuense sp. nov. is proposed; the type strain is BA-3T ( = CCTCC AB 2010217T = KCTC 23196T = KACC 16433T).

A Gram-stain-negative, aerobic and short rod-shaped bacterial strain, designated LD6T, was isolated from a forest soil sample in Suwon, Gyeonggi-do, Republic of Korea. Strain LD6T grew at 10–37 °C (optimal temperature, 28 °C), and tolerated pH 8.0 and 2 % (w/v) NaCl. Strain LD6T was related most closely to members of the genus Paraburkholderia , namely Paraburkholderia azotifigens NF2-5-3T (98.2 % 16S rRNA gene sequence similarity), P. megapolitana A3T (97.9 %), P. ginsengiterrae DCY85T (97.9 %) and P. caribensis MWAP64T (97.7 %). The strain grew well on R2A agar, tryptone soya agar, Mueller-Hinton agar and nutrient agar. The major polar lipid profile comprised phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, aminophospholipid and glycolipid. The major respiratory quinone was ubiquinone 8 (Q-8). The main fatty acids were C17 : 0 cyclo, C16 : 0, C16 : 0 3-OH, C19 : 0 cyclo ω8c and C12 : 0. The DNA G+C content of the isolated strain based on the whole genome sequence was 63.4 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between strain LD6T and its reference type strains ranged from 80.3 to 82.4%, and from 23.7 to 33.7%, respectively. Based on phenotypic, chemotypic and genotypic evidence, strain LD6T could be differentiated phylogenetically and phenotypically from the recognized species of the genus Paraburkholderia . Therefore, strain LD6T is considered to represent a novel species, for which the name Paraburkholderia flava sp. nov. is proposed. The type strain is LD6T (=KACC 21387T=JCM 33640T).

A Gram-stain-negative, aerobic, rod-shaped, non-spore-forming bacterium (ChimEc512T) was isolated from 56 host seedlings of the hyperaccumulating Anthyllis vulneraria legume, which was on an old zinc mining site at Les Avinières, Saint-Laurent-Le-Minier, Gard, South of France. On the basis of 16S rRNA gene sequence similarities, strain ChimEc512T was shown to belong to the genus Rhizobium and to be most closely related to Rhizobium endophyticum CCGE 2052T (98.4 %), Rhizobium tibeticum CCBAU 85039T (98.1 %), Rhizobium grahamii CCGE 502T (98.0 %) and Rhizobium mesoamericanum CCGE 501T (98.0 %). The phylogenetic relationships of ChimEc512T were confirmed by sequencing and analyses of recA and atpD genes. DNA–DNA relatedness values of strain ChimEc512T with R. endophyticum CCGE 2052T, R. tibeticum CCBAU 85039T, R. mesoamericanum CCGE 52T, Rhizobium grahamii CCGE 502T, Rhizobium etli CCBAU 85039T and Rhizobium radiobacter KL09-16-8-2T were 27, 22, 16, 18, 19 and 11 %, respectively. The DNA G+C content of strain ChimEc512T was 58.9 mol%. The major cellular fatty acid was C18 : 1ω7c, characteristic of the genus Rhizobium . The polar lipid profile included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol and phosphatidylcholine and moderate amounts of aminolipids, phospholipid and sulfoquinovosyl diacylglycerol. Although ChimEc512T was able to nodulate A. vulneraria, the nodC and nifH genes were not detected by PCR. The rhizobial strain was tolerant to high concentrations of heavy metals: up to 35 mM Zn and up to 0.5 mM Cd and its growth kinetics was not impacted by Zn. The results of DNA–DNA hybridizations and physiological tests allowed genotypic and phenotypic differentiation of strain ChimEc512T from species of the genus Rhizobium with validly published names. Strain ChimEc512T, therefore, represents a novel species, for which the name Rhizobium metallidurans sp. nov. is proposed, with the type strain ChimEc512T ( = DSM 26575 = CIP 110550T).

We carried out a polyphasic taxonomic study on a new halophilic strain designated 3(2)T, isolated from Meighan wetland, Iran. Cells of the novel strain were Gram-stain-negative, non-hemolytic, catalase- and oxidase-positive, rod-shaped, non-endospore-forming and motile. Cell growth occurred at 3–15 % NaCl (w/v; optimum, 5 %), pH 7.0–9.0 (optimum, pH 7.5–8.0) and 15–35 °C (optimum, 30 °C). 16S rRNA gene sequence comparisons confirmed the affiliation of strain 3(2)T to the class Gammaproteobacteria and the genus Halomonas with highest similarity to Halomonas daqiaonensis YCSA28T (98.4 %) and Halomonas ventosae Al12T (97.9 %). Experimental and in silico DNA–DNA hybridization values were 42.7 and 35.1% with H. daqiaonensis IBRC-M 10931T and 48 and 35.2% with H. ventosae IBRC-M 10566T, respectively, and indicated that they are different members of the same genus. The genome of the type strain was characterized by a size of 3.83 Mbp with 63 scaffolds and a G+C content of 64.8 mol%. Moreover, the average nucleotide identity values against H. ventosae Al12T and H. daqiaonensis YCSA28T were 88.8 and 88.5 %, respectively. The predominant respiratory quinone was Q-9 (92 %) with Q-8 (8 %) as a minor component. Major fatty acids were C16 : 0 cyclo, C19 : 0 ω8c, C16 : 1 ω7c and/or iso-C15:0 2-OH, C12 : 0 3-OH and C18 : 1 ω7c. The polar lipid profile of the strain contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphoaminoglycolipid and four unidentified phospholipids. According to our results, strain 3(2)T could be classified as a novel species in the genus Halomonas for which the name Halomonas lysinitropha sp. nov. is proposed. The type strain is 3(2)T (=IBRC M 10929T=LMG 29450T=CIP 111708T).

A novel Gram-stain-positive, motile, aerobic, non-spore-forming and slender rod-shaped actinobacterium, designated strain CTD02-10-2T, was isolated from deep sea water of the Indian Ocean. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain CTD02-10-2T was grouped into a separated branch with Chryseoglobus frigidaquae JCM 14730T (98.4 % nucleotide sequence identity). The respiratory quinones were menaquinones with 11, 12, 13 and 14 isoprene units and anteiso-C15 : 0, iso-C16 : 0, anteiso-C15 : 1 A and anteiso-C17 : 0 were the major fatty acids. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and three unknown glycolipids. The genome of strain CTD02-10-2T was 2.59 Mb, with a DNA G+C content of 69.6 mol% and contained genes involved in the biosynthesis of alkylresorcinol, ansamycin, and carotenoids. In silico DNA–DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between strain CTD02-10-2T and C. frigidaquae JCM 14730T were clearly below the thresholds used for the delineation of a new species. Based on its morphological and chemotaxonomic characteristics, as well as genotypic data, strain CTD02-10-2T was classified as a novel species of the genus Chryseoglobus , for which the name Chryseoglobus indicus sp. nov. is proposed. The type strain is CTD02-10-2T (=JCM 33842T=MCCC 1A16619T).

Emended Description

Two novel Gram-stain-negative, motile, catalase-negative and oxidase-positive strains of bacteria (JC131T and JC112) were isolated from Lonar, a soda lake in India. Based on 16S rRNA gene sequence similarity studies, strains JC131T and JC112 belong to the family Cohaesibacteraceae of the class Alphaproteobacteria and were most closely related to Cohaesibacter marisflavi DQHS21T (98.0 %) and Cohaesibacter gelatinilyticus CL-GR15T (96.0 %). Polar lipids of strains JC131T and JC112 include phosphatidylglycerol, phosphatidylethnolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol and two unidentified lipids (L1 and L2). Both strains have diplopterol, diploptene, an unidentified hopane (UH) and bacteriohopane derivatives (BHD1 and 2) as major hopanoids and an unidentified pigment (P1). The predominant isoprenoid quinone of both strains was ubiquinone-10 (Q10). Whole-cell fatty acid analysis of both strains revealed that C18 : 1ω7c was the predominant cellular fatty acid and significant proportions of C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), 11-methyl C18 : 1ω7c, C18 : 1ω9c, C18 : 0 and C20 : 1ω7c were also detected. The DNA G+C content of strains JC131T and JC112 was 54.6 and 53.8 mol%, respectively. The genome reassociation (based on DNA–DNA hybridization) of strains JC131T and JC112 with Cohaesibacter marisflavi NCCB 100300T ( = DQHS21T) was about 58 %, while between JC131T and JC112 it was about 87 %. On the basis of physiological, biochemical and chemotaxonomical properties, strains JC131T and JC112 are differentiated from the other two members of the genus Cohaesibacter . Strains JC131T and JC112 represent a novel species of the genus Cohaesibacter , for which the name Cohaesibacter haloalkalitolerans sp. nov. is proposed. The type strain is JC131T ( = KCTC 32038T = NBRC 109022T). An emended description of the genus Cohaesibacter is presented.
