Two Gram-stain-negative, aerobic, motile and rod-shaped bacteria, one designated as strain AXBT, capable of degrading estrogens, and another, YL23T, capable of degrading estrogen and bisphenol A, were isolated from activated sludge in Xiamen City, PR China. The optimum temperature and pH of both strains were 25–35 °C and pH 7.0–8.0. While strain AXBT could tolerate 3 % (w/v) NaCl, YL23T could only grow between 0–1 % (w/v) NaCl. They contained ubiquinone-10 as the major quinone, spermidine as the major polyamine, summed feature 8 (comprising C18:1ω6c and/or C18:1ω7c) as the major fatty acids and diphosphatidylglycerol, phosphatidylcholine, phosphatidyldimethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid as the major polar lipids. The DNA G+C contents of strains AXBT and YL23T were 63.6 and 63.7 mol%, respectively. Based on the results of 16S rRNA gene sequence analysis, strains AXBT and YL23T belonged to the genus Sphingobium . Strain AXBT was most closely related to Sphingobium chlorophenolicum NBRC 16172T (97.5 %) and Sphingobium chungbukense DJ77T (97.2 %), and strain YL23T was most closely related to S. chlorophenolicum NBRC 16172T (97.4 %) and S. quisquiliarum P25T (97.1 %). Average nucleotide identity values between these two strains and S. chlorophenolicum NBRC 16172T, S. chungbukense DJ77T, Sphingobium chinhatense IP26T, Sphingobium quisquiliarum P25T and Sphingobium japonicum UT26ST were from 80.7 to 85.8 %. In conclusion, strains AXBT and YL23T represent novel species of the genus Sphingobium , for which the names Sphingobium estronivorans sp. nov. and Sphingobium bisphenolivorans sp. nov. are proposed, respectively. The type strains of S. estronivorans and S. bisphenolivorans are AXBT (=MCCC 1K01232T=DSM 102173T) and YL23T (=MCCC 1K02300T=DSM 102172T), respectively.

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).

A Gram-stain-negative, aerobic, non-motile and rod-shaped marine bacterium, CW2-9T, was isolated from algae collected from Fujian Province in PR China. 16S rRNA gene sequence analysis showed that this strain was affiliated with the genus Tamlana in the family Flavobacteriaceae of the class Flavobacteriia and was very similar to the type strain Tamlana sedimentorum MCCC 1A10799T (96.3 % sequence similarity). The whole genome of strain CW2-9T comprised 3 997 513 bp with a G+C content of 34.3 mol%. The average nucleotide identity value between strain CW2-9T and T. sedimentorum MCCC 1A10799T was 73.8 %. Growth was observed from 15 to 40 °C (optimum, 30 °C), at pH from pH 5.0 to 10.0 (pH 8.0) and in the presence of 0–4 % (w/v) NaCl (0–1 %).

A Gram-stain-negative, yellow-pigmented bacterium, designated as L7T, was isolated from seeds of Alhagi sparsifolia Shap., a leguminous plant that grows in northwest PR China. Strain L7T was found to be non-flagellated, non-spore forming rods which can grow at 10–37 °C, pH 6.0–8.5 and in 0–3 % (v/w) NaCl concentration. The 16S rRNA gene sequence analysis showed that strain L7T belongs to the genus Chryseobacterium with sequence similarities to Chryseobacterium vietnamense GIMN1.005T (98.1%), C. bernardetii NCCTC13530T (98.0%), C. vrystaatense LMG 22846T (97.9%), C. nakagawai NCTC13529T (97.7%), C. shigense DSM 17126T (97.6%) and C. rhizosphaerae RSB3-1T (97.5%). The average nucleotide identity of strain L7T to 31 reference strains were 78.6–85.6 %, lower than the species delineation threshold of 95 %.

On the basis of 16S rRNA gene sequence analysis, strain NEAU-AAG5T belongs to the genus Actinomadura and shared highest sequence similarity with Actinomadura macra NBRC 14102T (98.8 %). Strain NEAU-AAG5T grows at 20–40 °C (optimum, 28 °C), pH 6–10 (optimum, pH 7) and has NaCl tolerance of 0–3 %. The menaquinones were identified as MK-9(H4) (4.2 %), MK-9(H6) (49.2 %) and MK-9(H8) (46.5 %). The major fatty acids were C16 : 0 (31.4 %), 10-methyl C18 : 0 (21.3 %) and C18 : 1  ω9c (15.7 %). The polar lipids were diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositolmannoside, phosphatidylglycerol and phosphoglycolipid.

Digital DNA–DNA hybridization between strain NEAU-AAG5T and its closest phylogenetic neighbour, A. macra NBRC 14102T, resulted in similarity value of 28.0 % (<70 %). Additionally, the average nucleotide identity was 84.2 % for A. macra NBRC 14102T. On the basis of phenotypic, genotypic and phylogenetic data, strain NEAU-AAG5T can be characterized to represent a novel species of the genus Actinomadura , for which the name Actinomadura litoris sp. nov. is proposed.

An alginate lyase-excreting bacterium, designated strain HB161718T, was isolated from coastal sand collected from Tanmen Port in Hainan, PR China. Cells were Gram-stain-negative rods and motile with a single polar flagellum. Its major isoprenoid quinone was ubiquinone 8 (Q-8), and its cellular fatty acid profile mainly consisted of C16 : 1 ω7c and/or C16 : 1 ω6c, C18 : 1 ω6c and/or C18 : 1 ω7c, C16 : 0, C17 : 0 10-methyl and C16 : 0 N alcohol. The G+C content of the genomic DNA was 44.1 mol%. 16S rRNA gene sequence analysis suggested that strain HB161718T belonged to the genus Alteromonas , sharing 99.5, 99.4, 99.2, 98.9 and 98.5 % sequence similarities to its closest relatives, Alteromonas macleodii JCM 20772T, Alteromonas gracilis 9a2T, Alteromonas australica H17T, Alteromonas marina SW-47T and Alteromonas mediterranea DET, respectively. The low values of DNA–DNA hybridization and average nucleotide identity showed that it formed a distinct genomic species. The combined phenotypic and molecular features supported the conclusion that strain HB161718T represents a novel species of the genus Alteromonas , for which the name Alteromonas portus sp. nov. is proposed. The type strain is HB161718T (=CGMCC 1.13585T=JCM 32687T).

An aerobic, Gram-stain-negative, rod-shaped bacterium, designated as strain R-22–3 w-18T, was isolated from Baiyangdian Lake in Xiong'an New Area, PR China. Growth was observed at 15–37 °C (optimum, 30 °C) and pH 7.0–10.0 (optimum, pH 8.0). 16S rRNA gene sequence analysis placed the strain in a separate branch in the Pseudomonas putida group, with Pseudomonas anguilliseptica DSM12111T as its closest phylogenetic relative (98.2 %). Whole-genome comparisons, using average nucleotide identity (ANI), average amino acid identity (AAI) and digital DNA–DNA hybridization (dDDH) analyses, confirmed low genome relatedness to the closely related Pseudomonas species [below the recommended thresholds of 95 % (ANI), 95 % (AAI) and 70 % (DDH) for species delineation]. Phenotypic characterization tests could also distinguish this strain from other related species of the genus Pseudomonas . Therefore, based on genetic and phenotypic evidence, it is clear that strain R-22–3 w-18T represents a novel species of the genus Pseudomonas , for which the name Pseudomonas xionganensis sp. nov. is proposed. The type strain is R-22–3 w-18T (=CGMCC 1.17250T=KCTC 72658T).
