Two Gram-negative, rod-shaped, motile, aerobic bacterial strains designated HY-14^T and HY-24 were isolated from the sludge of an anaerobic ammonium-oxidizing bioreactor. The strains could not grow with 5 % (w/v) NaCl, did not produce acid from D-glucose or utilize D-glucose, gluconate or citrate as a sole carbon source. Summed feature 3 and C_{16 : 0} were the most abundant fatty acids; hydroxyl fatty acids C_{12 : 0} 3-OH and C_{10 : 0} 3-OH were also present. Fatty acid C_{12 : 0} 2-OH was absent. The DNA G+C contents of strains HY-14^T and HY-24 were 50.6±0.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains HY-14^T and HY-24 formed a monophyletic clade within the genus Pseudomonas. The highest sequence similarities were to Pseudomonas pseudoalcaligenes DSM 50188^T (95.9 %). On the basis of phenotypic and phylogenetic properties, strains HY-14^T and HY-24 are proposed as a novel species of the genus Pseudomonas, for which the name Pseudomonas caeni sp. nov. is proposed. The type strain is HY-14^T (=KCTC 22292^T=CCTCC AB208156^T).

A transmission electron micrograph of a negatively stained cell of strain HY-14^T, showing a polar flagellum, is available with the online version of this paper.
