| 中文摘要 |
| 从长期受农药污染的土壤中分离到1株高效杀螟硫磷降解菌株Burkholderia sp.FDS-1,它能以3-甲基-4-硝基苯酚(MNP)为唯一碳源和氮源进行生长.该菌能在9h内将0.6mmol.L-1MNP完全转化成邻甲基对苯二酚(MHQ),并能继续降解MHQ.该菌降解MNP的最适温度和pH分别为30℃和7.0,菌株降解MNP的速率和起始接种量呈正相关.降解MNP的酶为诱导酶. |
| 英文摘要 |
| Strain Burkholderia sp.FDS-1 was isolated from long time pesticide polluted soil,which was capable of utilizing 3-methyl-4-nitrophenol(MNP) as the sole carbon and nitrogen source to support its growth.It could transform 0.6mmol/L MNP into methylhydroquinone(MHQ) completely in 9h and continue to degrade MHQ.The optimal temperature and pH for the degradation were 30℃ and 7.0 respectively.The degradation speed correlated positively to the initial inoculation amount.The MNP degrading related enzyme in this bacterium was the inducible enzyme. |
