A new quinoline antibiotic, aurachin RE, was isolated and identified from a culture broth of Rhodococcus erythropolis JCM 6824. The aurachin RE structure was determined based on NMR and mass spectrometric analysis. The structure is similar to that of aurachin C antibiotics that have been identified from Stigmatella aurantiaca. Compared to aurachin C, however, aurachin RE exhibits a wide and strong antimicrobial spectrum against both high- and low-GC Gram-positive bacteria.
