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.
