An aerobic, Gram-stain-negative, spiral or rod-shaped, non-spore-forming, diazotrophic bacterium (strain CC-LY743T) was isolated from a fermentative tank in Taiwan. Strain CC-LY743T was able to grow at 20–37 °C and pH 6.0–8.0 and tolerated up to 3.0 % (w/v) NaCl. It was positive for nitrogen fixation, with activity of 10.6 nmol ethylene h−1. 16S rRNA gene sequence analysis of strain CC-LY743T showed highest similarity to Azospirillum picis DSM 19922T (96.1 %), Azospirillum oryzae JCM 21588T (96.0 %) and Azospirillum rugosum DSM 19657T (96.0 %) and lower similarity (<96.0 %) to all other Azospirillum species. Highest nifH gene sequence similarities were obtained with Azospirillum brasilense BCRC 12270T (92.0 %), Azospirillum formosense BCRC 80273T (92.3 %) and A. rugosum DSM 19657T (91.8 %). It was positive in the rapid identification by a genus-specific primer set. The predominant quinone system was ubiquinone 10 (Q-10) and the DNA G+C content was 69.6±0.1 mol%. The major fatty acids found in strain CC-LY743T were n-C16 : 0, C19 : 0 cyclo ω8c, C14 : 0 3-OH/C16 : 1 iso I, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c. Based on its phylogenetic, phenotypic and chemotaxonomic features, strain CC-LY743T is considered to represent a novel species within the genus Azospirillum for which the name Azospirillum fermentarium sp. nov. is proposed. The type strain is CC-LY743T ( = BCRC 80505T = JCM 18688T = LMG 27264T).

A novel aerobic, Gram-stain-negative, motile bacterium, designated strain BUT-10T, was isolated from the sludge of a pesticide manufacturing factory in Kunshan, China. Cells were rod-shaped (0.4–0.45×0.9–1.4 µm) and colonies were white, circular with entire edges and had a smooth surface. The strain grew at 25–37 °C, at pH 6.0–8.0 and with 0–0.5 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain BUT-10T was a member of the genus Phenylobacterium , and showed highest sequence similarities to Phenylobacterium muchangponense A8T (97.49 %), Phenylobacterium immobile DSM 1986T (97.14 %) and Phenylobacterium lituiforme FaiI3T (96.34 %). Major fatty acids (>5 %) were summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), C16 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). The major isoprenoid quinone was ubiquinone-10. The DNA G+C content was 71.85 mol%. Strain BUT-10T showed low DNA–DNA relatedness with P. muchangponense A8T (15.7±2.9 %) and P. immobile DSM 1986T (12.8±1.1 %). On the basis of the phenotypic, phylogenetic and genotypic data, strain BUT-10T is considered to represent a novel species of the genus Phenylobacterium , for which the name Phenylobacterium kunshanense sp. nov. is proposed. The type strain is BUT-10T ( = CCTCC AB 2013085T = KCTC 42014T).

An ivory/yellow, Gram-stain-negative, short-rod-shaped, aerobic bacterial strain, designated JC2948T, was isolated from a soil sample taken from Gwanak Mountain, Republic of Korea. 16S rRNA gene sequence analysis indicated that strain JC2948T belongs to the genus Burkholderia . The test strain showed highest sequence similarities to Burkholderia tropica LMG 22274T (97.6 %), Burkholderia acidipaludis NBRC 101816T (97.5 %), Burkholderia tuberum LMG 21444T (97.5 %), Burkholderia sprentiae LMG 27175T (97.4 %), Burkholderia terricola LMG 20594T (97.3 %) and Burkholderia diazotrophica LMG 26031T (97.1 %). Based on average nucleotide identity (ANI) values, the new isolate represents a novel genomic species as it shows less than 90 % ANI values with other closely related species. Also, other phylosiological and biochemical comparisons allowed the phenotypic differentiation of strain JC2948T from other members of the genus Burkholderia . Therefore, we suggest that this strain should be classified as the type strain of a novel species of the genus Burkholderia . The name Burkholderia monticola sp. nov. (type strain, JC2948T = JCM 19904T = KACC 17924T) is proposed.

A novel Gram-negative-staining strain, designated 6.2ST, was isolated from a soil sample and identified as a biosurfactant producer. Its taxonomic position was investigated using a polyphasic approach. The cells were non-motile, non-spore-forming rods. The organism grew optimally at 30-37 °C, with 0–3 % (w/v) NaCl, and at pH 7.0. Based on 16S rRNA gene sequence analysis, strain 6.2ST was found to be a member of the genus Sphingobacterium and was most closely related to four type species of the genus, showing sequence similarities of 96.8–98.9 %. Partial chaperonin 60 (cpn60) gene sequence analysis was useful in resolving the phylogenetic relationships between strain 6.2ST and closely related taxa, with similarities ranging from 85.5 % (with Sphingobacterium thalpophilum DSM 11723T) to 90.3 % (with Sphingobacterium canadense CR11T and Sphingobacterium multivorum JCM 21156T). The results of DNA–DNA hybridization experiments between the novel strain and its closest relatives gave a DNA–DNA relatedness value of less than 70 %, and consequently confirmed that this new strain did not belong to a previously described species of the genus Sphingobacterium . The major fatty acids were summed feature 3 (iso-C15 : 0 2 OH and/or C16 : 1ω7c); iso-C15 : 0; iso-C17 : 0 3-OH and C16 : 0. The G+C content of the genomic DNA was 40.0 mol%. According to its phenotypic and genotypic characteristics and the phylogenetic data, strain 6.2ST represents a novel species of the genus Sphingobacterium , for which the name Sphingobacterium detergens sp. nov. is proposed. The type strain is 6.2ST ( = CECT 7938T = LMG 26465T).

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).
