Labris Portucalensis F11A Strain of Aerobic Bacterium From the Xanthobactereae Family, Can Break Down and Transform at ThreeS of-and PolyFluoroarkyl Substances (PFAS) C Byprodusts, According to New Research.
Labris Portucalensis F11 CAN BE POTENTIALLY USED FOR PFAS BIODEGRADADATION in CONTAMINATED ENVIRONMENTS. Image Credit: Wijayahena et alDOI: 10.1016/J.SCITOTOTENV.2024.178348.
“The Bond Between Carbon and Fluorine Atoms IS IS STRONG, SO MOST MICROBES CANNOT Use IT AN ENERGY SOURCE,” ER at the University at buffalo and suny.
“THE Labris Portucalensis F11 Bacterial Strain Developed The Ability to CHOP AWAY THE FLUORINE AND EAT THE CARBON.
Labris Portucalensis F11 Was Isolated from the SOIL OF ANDUSTRIAL SITE in PORTUGAL AND HAD Utical Contaminants. However, it Had Never BeeN Tested on Pfas.
In The New Study, Professor AGA and HER COLLEAGUES FOUND THAT Labris Portucalensis F11 METABOLIZED OVER 90% of OF Perfluorooctane Sulfonic Acid (PFOS) Following An Exposit of 100 Days.
PFOS Is ONE OF THE TYQUENTLY DETECTED TYPES OF PFAS AND WAS DESIGNATED HAZARDOUS BY THE US ENVIRONMENTAL PROTECTION AGENCYT Year.
Labris Portucalensis F11 ALSO BROKE down LOMER SULFONATE.
UNLIKE MANY PRIOR STUDIES ON PFAS-DEGRADING BACTERIA, The New Study Accounted for Shorter-Chain Breain Breakdown Products-or Metabolites.
In some case, Labris Portucalensis F11 EVEN REMOVED FLUORINE FROM The Metabolites or Broke Them Down to Minute, Undetector Levels.
“Many Previbility Studies Have Only Degradation of Pfas, But Not the Formation of Metabolites,“ SAID MINDULA WIJAYAHENA E University at Buffalo and Suny.
“WE Not ONLY ACCOUNTED FOR PFAS Byprodusts But Found some of Them Continued to Be Further Degradeded by The Bactteria.”
PFAS ARE A GROUP OF UBIQUITOUS CHEMICALS WIDELY USED SINCE THE THE 1950S in EVERYTHING from Nonstick Pans to Fire-Fighting Materials.
THEY'RE At the Can USE THEIR CARBON as an enERGY SOURCE.
“IF BACTERIA SURVIVE IN A HARSH, POLLUTED ENVIRONMENT, It's Probable Vecause THEY HAVE ADAPTED TO USE SURROUNDING CHEMICAL POLLUTANTS AS AS AS ASO RCE SO THEY DON'T Starve, “Professor AGA SAID.
“Through Evolution, SOME BACTERIA CAN DEVELOP EFFECTIVE MECHANISMS to USE Chemical Contaminants to Help Them Grow.”
THE Findings Were publiced in the journal Science of the total Environment.
