Abstract

A Gram-positive actinobacterium, strain RKJ300, capable of utilizing -nitrophenol and 2,4-dinitrophenol, was isolated from a pesticide-contaminated site in India. The morphological and chemotaxonomic properties of the isolate were typical of members of the genus . The DNA G+C content was 72 mol%. Strain RKJ300 exhibited the highest level of sequence similarity with NCIMB 13082 (99.3 %), followed by DSM 43205 (98.8 %), MBS1 (98.6 %) and DNP505 (98.1 %). The low levels of DNA–DNA relatedness (49–58 %) with the above micro-organisms, and the differences in the biochemical and physiological properties, suggest that strain RKJ300 should be classified within a novel species of the genus , for which the name sp. nov. is proposed. The type strain is RKJ300 (=MTCC 7085=JCM 13270).
