Tóm tắt
Organophosphate flame retardants (OPFRs), widely used in industrial applications, pose potential risks to human health due to environmental contamination. This study aimed to isolate and identify OPFR-degrading bacteria from wastewater samples collected from the To Lich River. Samples were enriched in a medium supplemented with OPFRs, resulting in the isolation of 10 bacterial strains. Based on 16S rRNA gene analysis, the isolates belonged to the genera Achromobacter, Pseudomonas, Bordetella, and Rhizobium. All strains showed OPFRdegrading capacity, but Achromobacter sp. BWTL6 and Rhizobium sp. BWTL7 exhibited the highest efficiency, degrading all five tested OPFRs. Notably, both strains degraded over 70 % of tris(1,3-dichloro-2-propyl) phosphate (TDCPP) at 10 mg/L within 7 days and utilized other OPFRs, including tris(2-chloroethyl) phosphate (TCEP), triethyl phosphate (TEP), tris(2- butoxyethyl) phosphate (TBEP), and trimethyl phosphate (TMP) , for growth, with removal rates ranging from 40 - 58 %. Additionally, Bordetella sp. BWTL3 degraded 61.5 % of TDCPP and 97.7 % of TBEP. These findings highlight the potential of Achromobacter and Rhizobium strains for bioremediation of OPFR-contaminated environments.
