用富集培养的方法从农药厂污水排放口的污泥中分离筛选到3株以氯氰菊酯为唯一碳源进行生长的真菌,分别命名为TS-203、TS-205和TS-306.经鉴定3株真菌分别属于土生曲霉组(Aspergillus terreus)、毛链孢属(Monilochaetes)和镰孢霉属(Fusarium).分别测定了不同碳源、pH、培养温度及氯氰菊酯浓度对真菌生长量和降解能力的影响.结果表明,以氯氰菊酯为唯一碳源且浓度为50~ 150 mg/L,pH 6.0~8.0,培养温度30~40℃时,真菌的生长量较大,降解效果较好.本研究对氯氰菊酯农药残留的生物修复研究和应用具有十分重要的意义,可为今后治理氯氰菊酯残留污染提供参考.
用富集培養的方法從農藥廠汙水排放口的汙泥中分離篩選到3株以氯氰菊酯為唯一碳源進行生長的真菌,分彆命名為TS-203、TS-205和TS-306.經鑒定3株真菌分彆屬于土生麯黴組(Aspergillus terreus)、毛鏈孢屬(Monilochaetes)和鐮孢黴屬(Fusarium).分彆測定瞭不同碳源、pH、培養溫度及氯氰菊酯濃度對真菌生長量和降解能力的影響.結果錶明,以氯氰菊酯為唯一碳源且濃度為50~ 150 mg/L,pH 6.0~8.0,培養溫度30~40℃時,真菌的生長量較大,降解效果較好.本研究對氯氰菊酯農藥殘留的生物脩複研究和應用具有十分重要的意義,可為今後治理氯氰菊酯殘留汙染提供參攷.

Using the method of enrichment culture, 3 cypermethrin-degrading fungi,with cypermethrin as sole carbon source,were isolated from sludge at sewage outlet of the pesticide factory and named TS-203, TS-205 and TS-306. The 3 fungal isolates were identified as Aspergillus terreus, Monilochaetes and Fusarium. The effects of different carbon sources, pH, temperature and cypermethrin concentration on fungal growth and biodegradation ability were determined. The results showed that the fungal growth and biodegradation rates were higher when cypermethrin was the sole carbon source with concentration of 50~ 150 mg/L, pH 6.0~8.0 and temperature 30 ~40 ℃. The study has the extremely vital significance for bioremediation of cypermethrin residue as well as its application, and has provided references for the residue pollution control of cypermethrin in the future.
