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.
对从印度北方邦东部十个不同受胁迫农业生态位分离出的20株细菌菌株针对细菌、酵母和霉菌的抗菌活性进行了评估。对11株显示出强抗菌活性的分离株进行了表征。通过紫外（UV）吸收光谱对8种抗真菌化合物进行了纯化和部分表征，并分为多烯类和非多烯类。对4株分离株产生的抗菌代谢产物进行了纯化和化学表征，其中一株分离株（AB）产生了一种新形式的橄榄酸，其他三株分离株（C5、Py和M4）产生了具有吩恶嗪核的抗菌化合物。
