| 摘 要： | 通过富集培养技术从长期受丁草胺污染的污泥中分离出一株丁草胺高效降解细菌,命名为P10,经形态特征、生理生化特征和16S rDNA序列同源性分析,将该菌株鉴定为克雷白氏杆菌属(klebsiella sp.)。P10在30℃,pH 7.0条件下7 d可降解89.6%的丁草胺;在28℃,16 h光照和8 h黑暗的条件下培养10 d,该菌株对药害植株修复效果明显。

| Abstract: | A strain of butachlor degrading bacterium was isolated from long-term butachlor contaminated soil by enrichment culture technology,which was named as P10.According to morphologic,physiological and biochemical characteristics as well as homology of 16S rDNA sequence,the P10 was identified as an klebsiella sp..The P10 can degrade 89.6% of butachlor when conditions were 30℃,pH value=7.0,7 d;when culture of contaminated plant with P10 at 28℃ for 10 d with 16 h of illumination and 8 h of darkness,the bioremediation effect was obvious. |
