ABSTRACT
A soil organism identified as Streptomyces libani var. soldani was found to produce 4-thiouracil. The product was isolated in a yield of 150 µg/ml of filtered beer and characterized by C-13 magnetic resonance and high-resolution mass spectroscopy. The product has a broad antibacterial spectrum but low specific activity.
