Description
A new antibiotic O-2867 inhibiting the growth of Piricularia oryzae, a plant pathogenic fungus of rice, was isolated from a Streptomyces sp. Antibiotic O-2867 is water-soluble, amphoteric and consists of 2 components, O- 2867-α and β. O-2867-α was obtained as an amorphous powder and O-2867-β as colorless needles. Both antibiotics are active against P. oryzae in vitro but are not effective in pot tests using rice plants infected with P. oryzae.
