| 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 results 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. |
