摘　　要：[目的]研究烟台海岸潮间带泥样中放线菌分布规律及抑菌活性。[方法]采用常规分离培养和琼脂块拮抗性测定法。[结果]从烟台海岸潮间带泥样中共分离得到357株放线菌,拮抗细菌的放线菌菌株数比拮抗真菌的多,抗革兰氏阴性细菌的放线菌菌株数较抗革兰氏阳性细菌的多,拮抗青霉的放线菌菌株数多于抗白色假丝酵母的放线菌菌株数;从泥样分离筛选所得的拮抗性放线菌中,中等拮抗性放线菌占多数,而且随着参试靶标菌个数的增加,对靶标菌均有拮抗性的放线菌菌株数却在减少。[结论]为进一步开发利用烟台海岸的海洋放线菌资源奠定了基础。[Objective] The distribution and antimicrobial activity of marine actinomycetes from Coast Yantai was studied.[Method] The normal isolating and agar block methods were used to do the experiment.[Result] The results indicated that 357 strains of marine actinomycetes were isolated from various places along Coast Yantai,and there were more antimicrobial Actinomycetes against bacteria than fungi,more antimicrobial Actinomycetes against G-bacteria than G＋ bacteria,and more antimicrobial Actinomycetes against Penicillium sp.than Candida albicans.The antimicrobial action of most antimicrobial actinomycetes was midding,and the quantities of broad-spectrum antimicrobial actinomycetes were a few.[Conclusion] These study may provide the basis for further exploration of marine-derived actinomycetes from Coast Yantai.
