阿特拉津降解菌ZXY-2的培养基
摘要：
阿特拉津降解菌ZXY‑2的培养基，它涉及一种阿特拉津降解菌ZXY‑2培养基。本发明的目的是为了解决现有用于培养节杆菌Arthrobacter sp.ZXY‑2所用的组成成分种类多且成本高的技术问题，阿特拉津降解菌ZXY‑2的培养基由蔗糖和Na2HPO4·12H2O溶于蒸馏水制成。阿特拉津初始浓度为50mg/L。所述培养基培养条件为pH 9，温度34.04℃，接菌量10％(v/v)，摇床转速150r/min。本发明的培养基只有两种成分。应用本发明的培养基培养细菌ZXY‑2，4h内可完全降解初始浓度50mg/L的阿特拉津，细胞密度可达2×108CFU/ml，降解效率达12.73mg·L‑1·h‑1。
摘要（英）：

The invention relates a culture medium for atrazine degradation bacteria ZXY-2. By the aid of the culture medium, technical problems of large quantities of types of compositions for cultivating Arthrobacter sp. ZXY-2 and high cost can be solved. The culture medium for the atrazine degradation bacteria ZXY-2 is made of cane sugar and Na2HPO4 12H2O which are dissolved in distilled water. The initial concentration of atrazine is 50 mg/L. Culture conditions of the culture medium include the pH (potential of hydrogen) is 9, the temperatures are 34.04 DEG C, the inoculated pathogen quantities are 10% (v/v), and the rotational speeds of shakers are 150 r/min. The culture medium has the advantages that the culture medium only comprises two components; the culture medium can be applied to cultivating the atrazine degradation bacteria ZXY-2, accordingly, the atrazine with the initial concentration of 50 mg/L can be completely degraded within 4 h, the cell density can reach 2*100<8> CFU/ml, and the degradation efficiency can reach 12.73 mg L-1 h-1.
