Bioremediation of perfuorochemicals: current state and the way forward

Penulis: Risky Ayu Kristanti,Kuok Ho Daniel Tang
Perfuorochemicals are widely found in the environment due to their versatile uses and persistent nature. Perfuorochemicals have also been detected in human and animals due to direct or indirect exposures, giving rise to health concerns. This review aims to examine the bioremediation of perfuorochemicals with plants, bacteria and fungi, including their efciency and limitations. It also aims to propose the future prospects of bioremediation of perfuorochemicals. This review retrieved peerreviewed journal articles published between 2010 and 2021 from journal databases consisting of Web of Science, Scopus and ScienceDirect. This review shows that multiple Pseudomonas species could degrade perfuorochemicals particularly perfuoroalkyl acids under aerobic condition. Acidimicrobium sp. degraded perfuoroalkyl acids anaerobically in the presence of electron donors. A mixed Pseudomonas culture was more efective than pure cultures. Multiple plants were found to bioconcentrate perfuorochemicals and many demonstrated the ability to hyperaccumulate perfuoroalkyl acids, particularly Festuca rubra, Salix nigra and Betula nigra. Fungal species, particularly Pseudeurotium sp. and Geomyces sp., have the potential to degrade perfuorooctanoic acid or perfuorooctane sulphonic acid. Perfuorochemicals bioremediation could be advanced with identifcation of more candidate species for bioremediation, optimization of bioremediation conditions, mixed culturing, experiments with environmental media and studies on the biochemical pathways of biotransformation. This review provides comprehensive insight into the efciency of diferent bacterial, plant and fungal species in perfuorochemicals bioremediation under diferent conditions, their limitations and improvement.
