PFAS biodegradation by Labrys portucalensis F11: evidence of chain shortening a...
Wijayahena, Mindula K.; Moreira, Irina S.; Castro, Paula M. L.; Dowd, Sarah; Marciesky, Melissa I.; Ng, Carla; Aga, Diana S.The biodegradation of three per- and polyfluoroalkyl substances (PFAS), namely perfluorooctane sulfonic acid (PFOS), 6:2-fluorotelomer sulfonic acid (6:2 FTS), and 5:3-fluorotelomer carboxylic acid (5:3 FTCA), were evaluated using Labrys portucalensis F11, an aerobic bacteria known to defluorinate fluorine-containing compounds. Cultures of L. portucalensis F11 were grown in minimal salts media and treated with ...
Bacterial degradation of perfluorooctane sulfonic acid (PFOS): detection of by-...
Wijayahena, Mindula K.; Moreira, Irina S.; Wallace, Joshua S.; Castro, Paula M. L.; Aga, Diana S.Introduction: Per- and poly-fluoroalkyl substances (PFAS) are highly fluorinated synthetic chemicals with a wide variety of uses1,2. The carbon- fluorine bonds exhibit very high bond dissociation energies: around 536 kJ/mol, making PFAS generally resistant to degradation by oxidation, thermal treatment, and biological mechanisms, which has led to their classification as “forever chemicals”3. Strategies to enhan...

The carbon- fluorine bonds exhibit very high bond dissociation energies: around 536 kJ/mol, making PFAS generally resistant to degradation, which has led to their classification as “forever chemicals”3. Strategies to enhance the biodegradation of these compounds are of great intere...
