  • 摘要: 通过选择性富集、驯化培养、划线分离纯化,从三峡大学求索溪及宜昌某化工集团污水处理厂次生池、终生池和排污口4处活性污泥中分离得到菌株XF100,其中排污口的活性污泥中菌株XF100含量最大,其降解能力最强.经API鉴定,菌株XF100为水生棒状杆菌(Corynebacterium aquaticum).由单因子优化法实验得出菌株XF100降解草甘膦废水的最适条件:温度为30℃,pH为9.0,底物浓度为300ml·l-1.最适条件下草甘膦废水降解率可达79.46%,其矿化程度较高.
    Abstract: Glyphosate wastewater adding a certain concentration of CaCl2 for pretreatment,treated wastewater for biodegradation.Strain XF100 was isolated from the activated sludge of Qiusuo River in Three Gorges University,secondary pool,final pool and outfall of sewage treatment works in the Chemical Group through selective enrichment,domestication,crossed separation and purification.It have the largest content in outfall of sewage treatment works in the Chemical Group and the best degradation.It is preliminary identified as Corynebacterium aquaticum through API.The optimum conditions of strain XF100 degradation:temperature 30℃,pH9.0,wastewater concentration 300 ml·l-1 by the single factor experimental.In this condition,glyphosate wastewater degradation rate reaches up to 79.46%.The mineralization degree is the highest.
