Treating and purifying waste polluted by tributyl phosphate, comprises incubation with photosynthetic purple bacteria species, optionally modified for over expression of cytochrome P450

摘要

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).
