摘要: 应用双层平板计数技术对厦门西海域海水沉积物中4环多环芳烃-芘降解菌数量调研结果表明，除靠近马銮湾养殖区站位Ⅵ 外，芘污染较严重站位Ⅳ 样品中芘降解菌数量为4．7万个/g (干物质量)，而芘污染相对较轻站位Ⅱ样品中芘降解菌数量为1．2万个/g (干物质量)，海水沉积物中芘含量与芘降解菌数量呈正相关。Abstract: Pyrene-contaminated sites of Xiamen western sea sediments are evaluated by using overlayer technique．The resuits show that the samples collected from the sediments with a high concentration of Pyrene contain 47 thousand Pyrene-degrading bacteria per gram while the samples collected from the sediments with a low concentration of Pyrene contain 12 thousand Pyrene degrading bacteria per gram．The number of Pyrene-degrading bacteria is positively related with the concentration of Pyrene．
