Abstract

A Gram-positive, aerobic, non-motile, non-endospore-forming rod-shaped bacterium with ibuprofen-degrading capacity, designated strain I11, was isolated from activated sludge from a wastewater treatment plant. The major respiratory quinone was demethylmenaquinone DMK-7, C cis9 was the predominant fatty acid, phosphatidylglycerol was the predominant polar lipid, the cell wall contained -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 I11 were CECT 7603 (96.8 % similarity), DSM 18081 (96.6 %) and DSM 16676 (96.6 %). Phenotypic characterization supports the inclusion of strain I11 within the genus (phylum Actinobacteria) However, distinctive features and 16S rRNA gene sequence analysis suggest that is represents a novel species, for which the name sp. nov. is proposed. The type strain is I11 ( = DSM 25962 = CECT 8141).
