Degrading Bacterium

The taxonomic status of a methyl-parathion-degrading strain, OP-1T, isolated from a wastewater-treatment system in China, was determined using a polyphasic approach. The rod-shaped cells were Gram-staining-negative, non-spore-forming and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain belonged to the genus Burkholderia , as it appeared closely related to Burkholderia glathei ATCC 29195T (97.4 % sequence similarity), Burkholderia sordidicola KCTC 12081T (96.5 %) and Burkholderia bryophila LMG 23644T (96.3 %). The major cellular fatty acids, C16 : 0, C17 : 0 cyclo and C18 : 1ω7c, were also similar to those found in established members of the genus Burkholderia . The genomic DNA G+C content of strain OP-1T was 59.4 mol%. The level of DNA–DNA relatedness between the novel strain and the closest recognized species, Burkholderia glathei ATCC 29195T, was only 30 %. Based on the phenotypic, genotypic and phylogenetic evidence, strain OP-1T represents a novel species of the genus Burkholderia , for which the name Burkholderia zhejiangensis sp. nov. is proposed. The type strain is OP-1T ( = CCTCC AB 2010354T = KCTC 23300T).

Degrading Bacterium

A novel bacterium, designated BD-1T, was isolated from a sludge sample. Cells of the novel Gram-stain-negative strain were identified to be facultative anaerobic, non-motile and short rod-shaped. Growth occurred at 15–37 °C (optimum, 30 °C), pH 5.0–10.0 (pH 7.0) and in 0–4.0  % NaCl (2.0 %, w/v). The 16S rRNA gene sequence of strain BD-1T showed the highest sequence similarity to Ottowia thiooxydans DSM 14619T (97.0 %), followed by Ottowia pentelensis DSM 21699T (96.3 %) and less than 96 % to other related strains. The phylogenetic trees revealed that strain BD-1T clustered within the genus Ottowia . Summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c, 48.2 %), C16 : 0 (23.2 %) and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c, 8.6 %) were the major fatty acids (>5 %), and ubiquinone-8 was the respiratory quinone. Phosphatidylethanolamine, phosphatidylmethylethanolamine and phosphatidylglycerol were identified as the major polar lipids. Meanwhile, the G+C content of the DNA was 63.6 mol% based on the draft genome analysis. The average nucleotide identity and digital DNA–DNA hybridization values between strain BD-1T and DSM 14619T were 74.5 and 21.4  %, respectively. In addition, the novel strain completely degraded 500 mg l−1 phenylacetic acid within 72 h under the condition of 3 % NaCl. Given the results of genomic, phylogenetic, phenotypic and chemotaxonomic analyses, strain BD-1T was considered to represent a novel species of the genus Ottowia , for which the name Ottowia caeni sp. nov. is proposed. The strain is a potential resource for the bioremediation of phenylacetic acid contaminated water. The type strain is BD-1T (=CGMCC 1.18541T=KCTC 82183T).

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 methyl parathion (MP) degrading bacterial strain, designated MP-1T, was isolated from a waste land where pesticides were formerly manufactured in Jiangsu province, China. Polyphasic taxonomic studies showed that MP-1T is a Gram-stain-negative, non-spore-forming, rod-shaped and motile bacterium. The bacterium could grow at salinities of 0–1 % (w/v) and temperatures of 15–40 °C. Strain MP-1T could reduce nitrate to nitrite, utilize d-glucose and l-arabinose, but not produce indole, or hydrolyse gelatin. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that MP-1T belongs to the genus Burkholderia , showing highest sequence similarity to Burkholderia grimmiae DSM 25160T (98.5 %), and similar strains including Burkholderia zhejiangensis OP-1T (98.2 %), Burkholderia choica LMG 22940T (97.5 %), Burkholderia glathei DSM 50014T (97.4 %), Burkholderia terrestris LMG 22937T (97.2 %) and Burkholderia telluris LMG 22936T (97.0 %). In addition, the gyrB and recA gene segments of strain MP-1T exhibited less than 89.0 % and 95.1 % similarities with the most highly-related type strains indicated above. The G+C content of strain MP-1T was 62.6 mol%. The major isoprenoid quinone was ubiquinone Q-8. The predominant polar lipids comprised phosphatidyl ethanolamine, phosphatidyl glycerol, aminolipid and phospholipid. The principal fatty acids in strain MP-1T were C18 : 1ω7c/C18 : 1ω6c (23.3 %), C16 : 0 (16.8 %), cyclo-C17 : 0 (15.0 %), C16 : 1ω7c/C16 : 1ω6 (8.5 %), cyclo-C19 : 0ω8c (8.1 %), C16 : 1 iso I/C14 : 0 3-OH (5.7 %), C16 : 0 3-OH (5.6 %) and C16 : 02-OH (5.1 %). The DNA–DNA relatedness values between strain MP-1T and the three type strains ( B. grimmiae DSM 25160T, B. zhejiangensis OP-1T and B. glathei DSM 50014T) ranged from 24.6 % to 37.4 %. In accordance with phenotypic and genotypic characteristics, strain MP-1T represents a novel species of the genus Burkholderia , for which the name Burkholderia jiangsuensis sp. nov. is proposed, the type strain is MP-1T (LMG 27927T = MCCC 1K00250T).

Degrading Bacterium

A Gram-stain-positive, non-motile, chemo-organotrophic, mesophilic, aerobic bacterium, designated A1T, was isolated from sludge of a wastewater treatment plant. Strain A1T showed good ability to degrade ammonia and grew well on media amended with methanol and ammonia. Strain A1T grew with 0–11 % (w/v) NaCl, at 20–42 °C, but not <15 or >45 °C and at pH 6–10 (optimum pH 8.0–9.0). The isolate was catalase-positive and oxidase-negative. The DNA G+C content was 70.7 mol%. A comparative analysis of 16S rRNA gene sequences revealed that strain A1T formed a distinct phyletic lineage in the genus Brevibacterium and showed high sequence similarity with Brevibacterium casei NCDO 2048T (96.9 %), Brevibacterium celere KMM 3637T (96.9 %) and Brevibacterium sanguinis CF63T (96.4 %). DNA–DNA hybridization revealed <43 % DNA–DNA relatedness between the isolate and its closest phylogenetic relatives. The affiliation of strain A1T with the genus Brevibacterium was supported by the chemotaxonomic data: predominant quinone menaquinone MK-7(H2); polar lipid profile containing diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid; characteristic cell-wall diamino acid meso-diaminopimelic acid; whole-cell sugars galactose, xylose and ribose; absence of mycolic acids; and major fatty acids iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The results of physiological and biochemical tests allowed phenotypic differentiation of strain A1T from members of the genus Brevibacterium . On the basis of the results in this study, a novel species, Brevibacterium ammoniilyticum sp. nov., is proposed. The type strain is A1T ( = KEMC 41-098T  = JCM 17537T  = KACC 15558T).

Gene Sequence Analysis

A Gram-positive, aerobic, non-motile, non-endospore-forming rod-shaped bacterium with ibuprofen-degrading capacity, designated strain I11T, was isolated from activated sludge from a wastewater treatment plant. The major respiratory quinone was demethylmenaquinone DMK-7, C18 : 1 cis9 was the predominant fatty acid, phosphatidylglycerol was the predominant polar lipid, the cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid and the G+C content of the genomic DNA was 74.1 mol%. On the basis of 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain I11T were Patulibacter ginsengiterrae CECT 7603T (96.8 % similarity), Patulibacter minatonensis DSM 18081T (96.6 %) and Patulibacter americanus DSM 16676T (96.6 %). Phenotypic characterization supports the inclusion of strain I11T within the genus Patulibacter (phylum Actinobacteria) . However, distinctive features and 16S rRNA gene sequence analysis suggest that is represents a novel species, for which the name Patulibacter medicamentivorans sp. nov. is proposed. The type strain is I11T ( = DSM 25962T = CECT 8141T).

Enrichment cultures inoculated with hydrothermally influenced nearshore sediment from Papua New Guinea led to the isolation of an arsenic-tolerant, acidophilic, facultatively aerobic bacterial strain designated PNG-AprilT. Cells of this strain were Gram-stain-negative, rod-shaped, motile and did not form spores. Strain PNG-AprilT grew at temperatures between 4 °C and 40 °C (optimum 30–37 °C), at pH 3.5 to 8.3 (optimum pH 5–6) and in the presence of up to 2.7 % NaCl (optimum 0–1.0 %). Both arsenate and arsenite were tolerated up to concentrations of at least 0.5 mM. Metabolism in strain PNG-AprilT was strictly respiratory. Heterotrophic growth occurred with O2 or nitrate as electron acceptors, and aerobic lithoautotrophic growth was observed with thiosulfate or nitrite as electron donors. The novel isolate was capable of N2-fixation. The respiratory quinones were Q-8 and Q-7. Phylogenetically, strain PNG-AprilT belongs to the genus Burkholderia and shares the highest 16S rRNA gene sequence similarity with the type strains of Burkholderia fungorum (99.8 %), Burkholderia phytofirmans (98.8 %), Burkholderia caledonica (98.4 %) and Burkholderia sediminicola (98.4 %). Differences from these related species in several physiological characteristics (lipid composition, carbohydrate utilization, enzyme profiles) and DNA–DNA hybridization suggested the isolate represents a novel species of the genus Burkholderia , for which we propose the name Burkholderia insulsa sp. nov. The type strain is PNG-AprilT ( = DSM 28142T = LMG 28183T).

A novel actinobacterium, designated strain F22T, was isolated from grassland soil collected from the Ziwuling area on the Loess Plateau, China. The novel strain was found to have morphological and chemotaxonomic characteristics typical of members of the genus Streptomyces . Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain F22T belonged to the genus Streptomyces , being most closely related to Streptomyces resistomycificus NBRC 12814T (98.28 % sequence similarity), Streptomyces ciscaucasicus NBRC 12872T (98.14 %), Streptomyces chartreusis NBRC 12753T (98.14 %) and Streptomyces canus NRRL B-1989T (98.14 %). In DNA–DNA hybridizations and comparisons of morphological and phenotypic data, strain F22T could be distinguished from all of its closest phylogenetic relatives. Strain F22T exhibited antibacterial and antifungal activity, especially against Staphylococcus aureus , Bacillus subtilis and Cylindrocarpon destructans. Based on the DNA–DNA hybridization data and morphological, phenotypic and phylogenetic evidence, strain F22T represents a novel species of the genus Streptomyces , for which the name Streptomyces ziwulingensis sp. nov. is proposed. The type strain is F22T ( = CCNWFX 0001T = JCM 18081T = ACCC41875T).

Members of the metabolically diverse order Nitrosomonadales inhabit a wide range of environments. Two strains affiliated with this order were isolated from soils in Germany and characterized by a polyphasic approach. Cells of strains 0125_3T and Swamp67T are Gram-negative rods, non-motile, non-spore-forming, non-capsulated and divide by binary fission. They tested catalase-negative, but positive for cytochrome c-oxidase. Both strains form small white colonies on agar plates and grow aerobically and chemoorganotrophically on SSE/HD 1 : 10 medium, preferably utilizing organic acids and proteinaceous substrates. Strains 0125_3T and Swamp67T are mesophilic and grow optimally without NaCl addition at slightly alkaline conditions. Major fatty acids are C16 : 1  ω7c, C16 : 0 and C14 : 0. The major polar lipids are diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyglycerol. The predominant respiratory quinone is Q-8. The G+C content for 0125_3T and Swamp67T was 67 and 66.1 %, respectively. The 16S rRNA gene analysis indicated that the closest relatives (<91 % sequence similarity) of strain 0125_3T were Nitrosospira multiformis ATCC 25196T, Methyloversatilis universalis FAM5T and Denitratisoma oestradiolicum AcBE2-1T, while Nitrosospira multiformis ATCC 25196T, Nitrosospira tenuis Nv1T and Nitrosospira lacus APG3T were closest to strain Swamp67T. The two novel strains shared 97.4 % 16S rRNA gene sequence similarity with one another and show low average nucleotide identity of their genomes (83.8 %). Based on the phenotypic, chemotaxonomic, genomic and phylogenetic analysis, we propose the two novel species Usitatibacter rugosus sp. nov (type strain 0125_3T=DSM 104443T=LMG 29998T=CECT 9241T) and Usitatibacter palustris sp. nov. (type strain Swamp67T=DSM 104440T=LMG 29997T=CECT 9242T) of the novel genus Usitatibacter gen. nov., within the novel family Usitatibacteraceae fam. nov.

Two novel actinobacterial strains, designated C9-5T and C3-43, were isolated from soil samples of a cave in Jeju Island, Republic of Korea, and subjected to taxonomic study by a polyphasic approach. The organisms exhibited a typical rod–coccus developmental cycle during growth and grew at 10–30 °C, pH 5–9 and 0–3 % (w/v) NaCl. In 92 single-copy core gene sequence analysis, strain C9-5T was loosely associated with Rhodococcus tukisamuensis , albeit sharing low 16S rRNA gene sequence similarity (97.4 %). A combination of morphological and chemotaxonomic characteristics supported assignment with the genus Rhodococcus . With respect to 16S rRNA gene sequence similarity, the novel isolates showed the highest identity to the type strain of Rhodococcus subtropicus (98.7 % sequence similarity), followed by Rhodococcus olei (98.5 %) and Rhodococcus pedocola (98.4 %).The average nucleotide identity and digital DNA–DNA hybridization values between strain C9-5T and members of the genus Rhodococcus were ≤81.5 and ≤37.1 %, respectively. A set of physiological and chemotaxonomic properties together with overall genomic relatedness differentiated the novel isolates from members of the genus Rhodococcus , for which the name Rhodococcus spelaei sp. nov. is proposed. The type strain is C9-5T (=KACC 19822T=DSM 107558T). Based on genome analysis performed here, it is also proposed that Rhodococcus biphenylivorans Su et al. 2015 is a later heterotypic synonym of Rhodococcus pyridinivorans Yoon et al. 2000, Rhodococcus qingshengii Xu et al. 2007 and Rhodococcus baikonurensis Li et al. 2004 are later heterotypic synonyms of Rhodococcus erythropolis (Gray and Thornton 1928) Goodfellow and Alderson 1979 (Approved Lists 1980), and Rhodococcus percolatus Briglia et al. 1996 and Rhodococcus imtechensis Ghosh et al. 2006 are later heterotypic synonyms of Rhodococcus opacus Klatte et al. 1995.

The optimum conditions for growth were observed at 30 °C, pH 6.0 and in the presence of 2 % (w/v) NaCl. The respiratory quinone was ubiquinone-10. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU 1637T was closely related to the genus Roseibium , with the highest similarity to Roseibium aestuarii NRBC 112946T (97.4 %), followed by Roseibium hamelinense NRBC 16783T (96.8 %), Roseibium aquae JCM 19310T (96.4 %), Roseibium sediminis KCTC 52373T (95.8 %) and Roseibium denhamense JCM 10543T (95.3 %). The predominant cellular fatty acids were C18 : 1  ω7c 11-methyl and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c). The major polar lipids consisted of diphosphatidylglycerol and phosphatidylglycerol. The average nucleotide identity values between the novel isolate and related strains ranged from 71.0 to 76.4 %, and the DNA−DNA hybridization values ranged from 19.3 to 20.3 %. The G+C content was 58.4 mol% and the whole-genome size was 4.6 Mb, which included 17 contigs and 3931 protein-coding genes. Based on the taxonomic data, strain CAU 1637T represents a novel species of the genus Roseibium , for which the name Roseibium limicola sp. nov. is proposed. The type strain is CAU 1637T (=KCTC 82429T=MCCC 1K06080T).
