摘　　要：以Halobacterium salinarum NRC817为敏感指示菌,用双层平板法对武汉大学中国典型培养物保藏中心保藏的19株嗜盐古生菌产生嗜盐菌素的情况进行了筛查,其中15株对Hbt.salinarum NRC817表现出明显拮抗,证实了前人的观点:分泌嗜盐菌素是嗜盐古生菌的普遍特征。Halocin production by CCTCC＇s haloarchaeal strains were detected utilizing a double-layer technique,with Halobacterium salinarum NRC817 as indicator organism.Among 19 strains tested,15 strains exhibited inhibitory activity again Hbt.salinarum NRC817 due to the production of halocins.Our result confirmed the established view that halocin production should be considered as a practically general feature of haloarchaea.
