Abstract

A new antibiotic, DB-2073, was isolated in crystalline form from the fermented broth of Pseudomonas sp. B-9004. The compound is a alkylresorcinol antibiotic. The antibiotic melts at 86-88°C. The molecular weight of 236 was determined by mass spectroscopy and the molecular formula was calculated as C15H24O2. The antibiotic has antimicrobial activity against Gram-positive bacteria, mycobacteria and fungi.
