摘要
比较了不同方法对厦门海区潮间带游动放线菌的分离效果和分析游动放线菌在不同材料中的种群数量分布。结果表明，在孢囊脱水－复水方法的基础上，采用重铬酸钾－放每菌酮－热处理－延长样品风干时间的联合方法，对样品污染细菌和霉菌有很好的抑制效果；海洋漂浮植物材料是游动放线菌的良好分离来源、数量超过１０＾２ＣＦＵ／ｇ干重；海洋潮间带植物材料的游动放线菌种属多样，但以链孢囊菌属为主，８０％的分离菌株具有抗菌活性。
The isolation methods for the actinoplanetes are compared and the ecological distribution of the actinoplanetes in the intertidal zone of Xiamen sea area is studied. The method, in which the sample is dried in air for 30 days, then treated in water bath at 55℃ for 10 minutes, and inoculated in the medium containing 50×10-6 K2CrO7 and 50×10-6 cyclolieximide, can obviously inhibit the bacterial and fungal growth. In the intertidal zone of Xiamen sea area, the populations of actinoplanetes are more than 200 CFU/g of dry sample, and the dominant genera is Streptosporangium. Among the actinoplanetes isolated, 80% of the strains are of have antimicrobial activity.
