abstract= A novel facultatively anaerobic, non-spore-forming, non-motile, catalase- and oxidase-positive, Gram-negative and rod-shaped bacterial strain, designated Y12T, was isolated from activated sludge of a wastewater bio-treatment facility. The strain was able to degrade about 90 % of added propanil (100 mg l−1) within 3 days of incubation. Growth occurred in the presence of 0–4.5 % (w/v) NaCl (optimum 0.5 %), at 10–40 °C (optimum 28 °C) and at pH 5.5–10.0 (optimum pH 7.0). Vesicular internal membrane structures and photoheterotrophic growth were not observed. The major respiratory quinone was ubiquinone-10 and the major cellular fatty acid was summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The genomic DNA G+C content of strain Y12T was 63.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain Y12T was a member of the genus Catellibacterium, as it showed highest sequence similarities to Catellibacterium caeni DCA-1T (99.1 %) and <96.0 % similarities with other species of the genus Catellibacterium. Strain Y12T showed low DNA–DNA relatedness values with C. caeni DCA-1T. Based on phenotypic, genotypic and phylogenetic properties, strain Y12T represents a novel species of the genus Catellibacterium, for which the name Catellibacterium nanjingense sp. nov. is proposed. The type strain is Y12T ( = CCTCC AB 2010218T  = KCTC 23298T). An emended description of the genus Catellibacterium is also presented.,
