|Abstract:||Antimicrobial activities of twenty bacterial strains isolated from ten different stressed agro-ecological niches of Eastern Uttar Pradesh, India were evaluated against bacteria, yeasts and molds. Eleven isolates showing strong antimicrobial activities were characterized. Eight antifungal compounds were purified and partially characterized by Ultra-Violet (UV) absorption spectra and grouped into polyenes and non-polyenes. Antibacterial metabolites produced by four isolates were purified and chemically characterized, of which one isolate (AB) produced a new form of olivanic acid, and other three isolates (C5, Py and M4) produced antibacterial compounds having phenoxazone nucleus.|
