    • The invention relates to: a method of treating liquid waste (liquid agricultural or industrial effluents or aquatic sites) which is loaded or polluted with tributyl phosphate (TBP), modified bacterial strains which can be used in the aforementioned treatment method, a method for monitoring changes in TBP pollution, and the device which is used to perform said treatment method. According to the invention, the liquid waste-treatment or -purification method essentially comprises: steps (1) consisting in bringing said liquid waste into contact with at least one non-sulphur purple photosynthetic bacterial strain which is resistant to TBP and which is selected from the group containing Rhodopseudomonas palustris (Rp. palustris), Rhodospirillum rubrum (Rs. rubrum), Rhodobacter capsulatus (Rb. capsulatus) or Rhodobacter sphaeroides (Rb. Sphaeroides) as well as the aforementioned modified bacterial strains in order to overexpress cytochrome P450 in conditions that enable the degradation of the TBP present in said waste, regardless of the initial TBP concentration; and (2) the recovery of the purified liquid effluents.
    • 本发明涉及一种处理用磷酸三丁酯(TBP)负载或污染的废液(液体农业或工业废水或水域)的方法,可用于上述处理方法的改良细菌菌株,监测方法 TBP污染的变化以及用于执行所述处理方法的装置。 根据本发明,液体废物处理或纯化方法基本上包括:步骤(1),其使所述废液与至少一种对TBP有抗性的非硫紫色光合细菌菌株接触,并且选自 该组包含红假单胞菌(Rop palustris),红紫苏(Rhodospirillum rubrum)(红霉素),红长棍菌(Rb.s capsulatus)或罗红假单胞菌(Rb.Sphaeroides))以及上述修饰的细菌菌株,以在条件中过表达细胞色素P450 使得能够降低存在于所述废物中的TBP,而不管初始TBP浓度如何; 和(2)净化液体流出物的回收。
