Abstract (en)
[origin: FR2854886A1] Method for treating or purifying liquid waste polluted by tributyl phosphate (TBP) by incubation with at least one purple, photosynthetic, non-sulfurous bacterium (A) resistant to TBP. (A) is Rhodopseudomonas palustris; Rhodospirillum rubrum; Rhodobacter capsulatus; or Rhodobacter sphaeroides, optionally modified to over express cytochrome P450, and able to degrade TBP when present at any concentration. Independent claims are also included for: (1) method for monitoring decomposition of TBP in waste by applying the new treatment then measuring residual TBP content in a test sample after at least 15 days; (2) kit for the new process that contains at least one (A); (3) strain of (A) in which the DNA includes at least one copy of a gene for P450; and (4) device for purifying liquid waste polluted by TBP comprising at least one decantation tank for treatment with (A).
