Abstract A novel Gram- negative, cream-colored, rod-shaped, aerobic, non-motile bacterium, designated MSA67T, was isolated from a subterranean sediment sample of the Mohe Basin in Northeast China. Strain MSA67T was detected to grow at 4–40°C (optimum, 28–30°C), pH 5.0–10.0 (optimum, pH 7.0) and in 0.0–8.0 % (w/v) NaCl (optimum, 2.0–3.0 %). Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain MSA67T was a member of the genus Devosia, with the highest similarity with D. riboflavina IFO13584T (98.0 %) and D. chinhatensis IPL18T (97.0 %). The major cellular fatty acids are C16:0, C18:1ω7c 11-methyl and C18:1ω6c and/or C18:1ω7c. The major polar lipids are diphosphatidylglycerol, phosphatidylglycerol, glycolipids and three unidentified phospholipids. The major respiratory quinone is ubiquinone 10 (Q-10). The genomic size of strain MSA67T is 4.1 MB and DNA G + C content is 63.6 %. Based on genotypic, phenotypic and phylogenetic results, strain MSA67T is concluded to represent a novel species of the genus Devosia, for which the name Devosia sediminis sp. nov. is proposed.

We isolated a strain coded Esc2AmT during a study focused on the microbial diversity of adult specimens of the bark beetle Hylesinus fraxini. Its 16S rRNA gene sequence had 99.4 % similarity with respect to its closest relative, Pseudomonas rhizosphaerae IH5T. The analysis of partial sequences of the housekeeping genes rpoB, rpoD and gyrB confirmed that strain Esc2AmT formed a cluster with P. rhizosphaerae IH5T clearly separated from the remaining species of the genus Pseudomonas. Strain Esc2AmT had polar flagella and could grow at temperatures from 4 °C to 30 °C. The respiratory quinone was Q9 and the main fatty acids were C16 : 0, C18 : 1ω7c and/or C18 : 1ω6c in summed feature 8 and C16 : 1ω7c and/or C16 : 1ω6c in summed feature 3. DNA–DNA hybridization results showed 51 % relatedness with respect to P. rhizosphaerae IH5T. Oxidase, catalase and urease-positive, the arginine dihydrolase system was present but nitrate reduction and β-galactosidase production were negative. Aesculin hydrolysis was positive. Based on the results from the genotypic, phenotypic and chemotaxonomic analyses, we propose the classification of strain Esc2AmT as representing a novel species of the genus Pseudomonas, for which we propose the name Pseudomonas coleopterorum sp. nov. The type strain is Esc2AmT ( = LMG 28558T = CECT 8695T).
