Bioaugmentation with Vaults: Novel In Situ Remediation Strategy for Transformation of Perfluoroalkyl Compounds

Abstract

The objective of this research was to develop an innovative in situ bioremediation technology using vault nanoparticles that will facilitate the degradation of poly- and perfluoroalkyl compounds (PFCs), and potentially other water contaminants, without the need for repeated bioaugmentation with active cultures or stimulation with nutrients. We designed a single-step method for encapsulating lignin peroxidases (LiP), manganese peroxidases (MnP), and laccases into vaults. Vault packaged enzymes were stable across a broader range of temperatures and pH, and in PFC-contaminated groundwater. Since vaults occur in nature, their application is unlikely to cause any risk for public health as well as the environment.
