Abstract

A -nitrophenol-degrading bacterial strain was isolated from industrial wastewater. This strain (NSP41) was identified as a member of the genus from chemotaxonomic characterizations and phylogenetic inference based on 16S rDNA sequence analysis. The G+C content is 71·4 mol%. The diamino acid in the cell-wall peptidoglycan is -diaminopimelic acid. The predominant menaquinone is MK-8(H). The cellular fatty acid profile is similar to those of species. 16S rDNA sequence analysis show that strain NSP41 is the most related to strains with a level of nucleotide similarity of 98·6%. The levels of 16S rDNA similarity between strain NSP41 and other species ranged from 93·8 to 95·1 %. This organism is distinguishable from some other species as well as strains by DNA–DNA relatedness data. This organism is different from strains in some phenotypic characteristics. Therefore, on the basis of the data presented, a new species of the genus is proposed. The type strain of the new species is strain NSP41 ( = KCTC 0457BP).
