摘要 洋葱伯克霍尔德菌CF-66能够抑制立枯丝核菌等若干植物病原菌和其它一些真菌的生长。CF-66菌发酵液的粗提液通过Sephadex-75pg、Sephacryl S-100柱层析分离纯化,获得抗菌物质CF66I。此抗菌物质耐热性强,耐碱,但在强酸性条件下不稳定。低浓度有机溶剂的存在有利于抑菌活性的提高。对其结构的研究表明CF66I是以(CH2CH2O)n为主要单元结构并带有酰氨键的化合物。 Burkholderia cepacia CF-66 isolated from compost showed antifungal activity against plant pathogens such as Rhizoctomia solani and some other fungi. CF66I produced by Burkholderia cepacia CF-66 was separated by gel chromatography using Sephadex-75pg and Sephacryl S-100 column. CF66I has very high degree of stability of antifungal activity under higher temperature and alkaline conditions. Some organic solvents could improve its activity at low concentration. The research for the structure of CF66I find that it is a compound with amide bonds and its main structural units is （CH2CH2O）n.
